6 General Description
GENERAL DESCRIPTION
The Drake model EH24, encoder host used with the SDE24
encoder modules, is a MPEG2 and MPEG4/H.264 SD
encoder system. The SDE24 encoder modules provide
standard definition encoding. The SDE24 encoders accept
analog NTSC video input from either composite or S video
sources and provide commercial quality MPEG2 or H.264,
480i video outputs in both DVB-ASI and RF QAM.Typical
applications are to provide MPEG video in MDUs, medical
facilities, libraries, stadium video networks, and other QAM
applications. There are two multiplexers in the EH24, one
providing an ASI output stream and one providing a stream
to the built in QAM modulator/upconverter.
SDE24
Each SDE24 module contains two encoders and if MPEG2
encoding is desired for two programs, two MPEG2 transport
streams can be generated. If MPEG4, H.264 encoding is
desired, each SDE24 module can encode one program to an
H.264 output stream. Another option is to encode one
program in MPEG2 and another program in H.264.

EH24 AND SDE24 FEATURES
The EH24 encoder host platform is a 19” rack mountable
chassis that is 2 RU tall and can accept up to six dual
program real time encoders, the SDE24 modules. Each
commercial quality SDE24 video and audio encoder module
can encode two separate programs into MPEG2 transport
streams or it can encode two programs, one into a MPEG2
stream and one into a MPEG4/H.264 stream. Each SDE24
module provides two sets of input connectors for NTSC
composite or S-video with stereo audio. Audio is encoded
using Dolby AC-3 encoding. Any number of SDE24 modules,
from one to six, may be installed in the EH24.
When the EH24 is fully loaded with six SDE24 modules, it
can provide MPEG2 encoding of twelve NTSC programs OR
it can provide H.264 encoding of six NTSC programs. It can
also provide encoding of six programs in H.264 and up to six
programs of MPEG2 simultaneously.
The EH24 also contains transport stream multiplexers that
can multiplex any or all of the programs streams from the
SDE24 encoders. The user may select what programs from
the SDE24s to include in the QAM output channel and also
the user can select, independent of the QAM output, what
programs to output via the DVB-ASI port. The QAM RF
output can be specified for either off-air or CATV frequency
plans in the 54 to 1002 MHz spectrum. The EH24 and
installed SDE24 modules are powered by a built in power
supply.

INSTALLATION AND MOUNTING NOTES
This equipment is designed to be installed in a standard 19” rack. When the unit is mounted above or below other rack
mounted equipment, a 1U space (1.75”) should be left between the unit and the other equipment to allow ambient air flow
between the units. No space is needed between EH24 units themselves due to the ventilation provided by their built in fans.
Connect the AC line cord to an appropriate source of 120 volt, 50/60 Hz AC power. The EH24 is always on once the AC
power cord is connected to its power source.

supply will accept an input voltage range of 90 VAC minimum
to 132 VAC maximum with a power line frequency of from 47
to 63 Hz. The maximum power consumption is 70 watts.
Programming and viewing of the various setup and operating
parameters is accomplished using the front panel back lit,
two line, sixteen character wide LCD along with the two LEFT
and RIGHT ‘ENCODER SELECT’ buttons and the five LEFT,
RIGHT, UP, DOWN and ENTER buttons. The name of the
parameter is on the top line of the display and the setting
value is on the bottom line.
To observe a certain parameter setting without intending to
change its value, just use the LEFT and RIGHT ENCODER
SELECT buttons and the LEFT and RIGHT arrow buttons to
navigate through the menus shown in the software flow chart
below. The current setting for each parameter is shown on
the bottom line of the display. Note that depending upon
certain settings, some screens are not needed and will be
skipped.
To make a change in the displayed parameter and its setting
and if this is the initial setup, you will want to enter the
‘program’ mode. To do this, press the ENTER button that is
located in the center of the four arrow buttons and hold in for
several seconds until the bottom line of the display begins to
flash.
After you are in the program mode (bottom line of screen
flashing) use the LEFT and RIGHT arrows to navigate among
screens and use the UP and DOWN arrows to change the
parameter setting. When ENTER is pressed, the new
settings will be loaded and stored and the unit will exit the
‘program’ mode. You may wish to not press ENTER until you
have gone through all screens and settings and then press
ENTER to save and load all changes in one step, OR you
can store just one or several parameters at a time and
reenter program mode to set the next. Either method is
acceptable.

10 Setup and Programming (continued)
This section provides additional details regarding the selectable
items shown in the ‘program’ mode on the Software Flow Chart on
page 9.
SETUP: EH24
UNIT ID: Select the desired unit identification number when
connecting the 'RS232 IN' connector to a PC or modem for remote
control using 'Drake Remote Control Software'. Numbers 1 thru
63 may be used. If zero (0) is selected, the PC will ignore the unit.
RS232 BAUD RATE: This setting determines the baud rate at
which the EH24 communicates with the remote PC. Settings
available are 2400, 4800, 9600 and 19,200. All units 'daisy
chained' to the remote PC or modem must be set to the same
baud rate.
ENCODER 1 THRU 12: These menu items provide the means for
selecting the desired output mode of operation for each of the
installed encoders. The available settings are DISABLED, QAM +
ASI, ASI, and QAM.
QAM MGT/VCT: This menu item provides a means for the user to
select either CVCT or TVCT tables or DISABLED for QAM
operation. TVCT is the typical setting.
QAM MAJOR CHANNEL: The user may use this menu entry to
define the QAM major channel number. The choices are OUTPUT
CHANNEL or USER DEFINED using an external PC with Drake
Digital Headend Remote Control Software.
ASI MGT/VCT: This menu item provides a means for the user to
select either CVCT or TVCT tables or DISABLED for ASI opera-
tion.
ASI MAJOR CHANNEL: The user may use this menu entry to
define the ASI major channel number. The choices are OUTPUT
CHANNEL or USER DEFINED using an external PC with Drake
Digital Headend Remote Control Software.
QAM MODE: This menu allows the user to set the modulation
type for the output. Choices range from QAM-16A through QAM-
1024B. 'A' suffixes indicate DVB compliant FEC and the B
suffixes indicate DigiCipher II FEC encoding. Note that the output
QAM mode usually must be QAM-256. For CATV systems using
DigiCipher II, select the QAM-256B mode. For DISH Network
QAM distribution or other DVB systems using DVB set tops,
choose the QAM-256A mode.
GRAY ENCODING: This menu is only available when QAM
modes QAM-16A through QAM-1024A, are selected. The choices
are DVB and DAVIC. Gray Encoding is normally not used for video
data.
QAM SYMRATE: Preset or Manual: If PRESET is selected, the
symbol rate will be automatically set to the ‘normal’ rate based on
the QAM mode that is selected and assuming a 6 MHz wide QAM
channel. If MANUAL is selected, pressing the right or left arrow
buttons will allow selection of symrates from 1.000 thru 7.000
MSym/Sec.
QAM SYMRATE: This menu item only appears of ‘Manual’ is
selected in the previously described menu item. It allows selection
of the output QAM baudrate or symbol rate. Set as required by the
set top box.
INTERLEAVER: This menu item only appears if QAM-64B, QAM-
256B, or QAM-1024B is selected and provides the means to set
the QAM modulator interleaver. Choose among the available
selections based upon your system / set top box requirements. For
typical 256-QAM DigiCipher II CATV systems, I128, J1 is the most
commonly used interleave setting but many other choices are
available. This menu does not appear in the adjust mode if the
QAM mode is A (DVB) as there is only one choice in the DVB
standard.
OUTPUT FORMAT: For normal operation, select NORMAL. For
system level set up, choose CW to provide a CW carrier at the
center frequency of the output channel for use in leveling a system
when a QAM power meter is not available. To disable all RF
output, select STANDBY. In the CW mode, the CW carrier can be
measured on a spectrum analyzer without a need to apply a
bandwidth correction or it can be measured with an analog meter
tuned to channel center. The CW power measured will equal the
channel QAM power when the modulator is returned to NORMAL
output mode. Usually QAM signals are set 5 dB to 10 dB below
analog NTSC channels when balancing a system.
PRBS menu entries are used for testing purposes only and should
normally not be selected by the user.
OUTPUT CHANMAP, OUTPUT CHANNEL: Select the desired
EIA CATV channel output using these two menus.
RF LEVEL: Select the desired RF output signal level. The
available range is between +45 dBmV and +56 dBmV, selectable
in 0.5 dB steps. The output accuracy is ± 1 dB.
SETUP: ENCODER xx
ENCODER SELECT: The LEFT and RIGHT buttons allow the
user to scroll through the encoder numbers for each encoder
installed in the EH24 as well as the EH24 itself. Use the LEFT and
RIGHT buttons to select the encoder to be programmed.
VIDEO: This menu entry allows the user to select between S-
VIDEO and COMPOSITE video input for each selected encoder.
FORMAT: Either MPEG2 or MPEG4 H.264 may be selected as
the output format for the selected encoder using this menu item.
Encoder 2 on a given SDE24 has no option. It is forced to
MPEG2.
RESOLUTION: The resolution of the video output of each
encoder may be selected from this menu item. The choices range
from 720 x 480 thru 353 x 240 as shown on the software flow chart
on page 9.
BRIGHTNESS, CONTRAST, SATURATION and HUE: These
menu items allow the user to assign each of these parameters of
the output video values from 0 to 255.
MAX AUDIO IN: This menu entry allows the user to set the
maximum audio input which may be input to the selected encoder.
The choices are 1 Vrms or 2 V rms.
AUDIO GAIN: The audio output level can be chosen from this
menu item by selection of the appropriate gain. The values range
from + 15 dB to - 15 dB. Audio output can also be completely
eliminated using the ‘MUTE’ selection.
AUDIO ENCODER: The SDE24 includes audio encoders for
Dolby Digital Stereo commercial encoding (AC3) or MPEG1 Layer
2 audio encoding (MP2). In the USA, the majority of applications
will use AC3 but if your network is using Annex A (DVB) set top
boxes, they may require the MPEG audio selection. Some TVs
and set top boxes will decode either mode but be sure to set the
encoder to the mode used by other programming on your system
to insure complete compatibility. The AUDIO ENCODE(R) menu
allows you to select either AC3 or MP2. Use the up/dn arrow keys
to toggle between the two settings.
OPERATING INSTRUCTIONS – FROM THE FRONT PANEL
1) Connect video and audio inputs to desired encoder
modules. Note, as viewed from the rear, the number 1
program will be on the left, the one closest to the RF output
connector. The number 2 program will be the next input to
the right.
2) Connect the outputs as desired.
3) Plug the EH24 into AC power. Allow 30 to 90 seconds for
boot-up.
4) From the front panel, use the ENCODER SELECT buttons
to choose among EH24 settings and settings for each
encoder. Use the ENTER button to enter program mode and
to save settings in memory. Use left and right arrows to
select a parameter and then use the up or down arrows to
change its value. Parameters values can only be changed
when the unit is in the program mode as indicated by slow
flashing of the front panel display. To enter program mode,
press the ENTER key and hold for 2 to 3 seconds.

up or down arrows to select which output or both outputs that
this encoder is to output to. Then press the right arrow once
to advance to ENCODER 2. Choose output for this one.
Proceed in this manner until all encoders have been directed
to the desired outputs. ENCODERs 1 and 2 will be the first
module, 3 and 4 the second module, 11 and 12 the sixth
module, etc. If an encoder is installed but you don’t plan to
use it, be sure to choose the DISABLED choice for any such
encoders.
8) Press the right arrow again after setting the 12 th encoder.
This should produce the QAM MGT/VCT screen. Usually
select TVCT by using up or down arrows.
9) Press right arrow again and observe the QAM MODE

RS232 remote control, choose 0.
17) Press the right arrow and observe RS232 BAUDRATE.
Set to 4800 unless otherwise directed.
18) Press the right arrow and observe that you are back to
the ENCODER 1 screen.
At this point, you can press ENTER to store all of the above
choices. Actually, you could store after setting just one item
or after two items, etc. But once you store a parameter(s),
you must renter the program mode to make any additional
adjustments.
All of the above settings can be set using a PC connected via
the RS232 port or through an Ethernet connection via the
DRAKE model SCTeci unit.
Having completed EH24 settings, above, you are now ready
to setup each individual encoder.
19) Press ENTER for 3 seconds to enter program mode.

Additional Information 13
ADDITIONAL INFORMATION
STANDBY MODE
The EH24 has a standby output mode which turns off the RF
output. This can be used when it is desirable to temporarily
disable the output without unplugging the AC line cord.
Select DISABLED in the ‘QAM MGT/VCT’ menu. Individual
encoders can be disabled or enabled when in the QAM mode
from the ‘ENCODER xx’ menu.
OVER TEMPERATURE SENSOR
Temperature monitoring is built into this product. If inad-
equate ventilation is provided, overheating may occur. If this
condition is detected, the default LCD message will change
to OVER TEMP. If this occurs, the problem should be
corrected as soon as possible. The unit will remain opera-
tional but the ventilation must be restored to prevent prema-
ture part failures due to overheating.
STATUS DISPLAYS
When the units are not in the program mode, status displays
are shown. The default display shows the QAM OUTPUT
Mbits/S. When the UP button is pressed, the version number
of the EH24 firmware is displayed. The DOWN button
toggles the display between QAM OUTPUT Mbits/S and ASI
OUTPUT Mbits/S.
REMOTE CONTROL AND MONITORING
The EH24 may be used with the Drake SCTeci or with the
'Drake Digital Headend Remote Control Software' program to
allow remote monitoring or control. Only version 3 or newer
of the software is compatible with the EH24.
Connect the RS232 cable coming from the SCTeci, PC, or
modem to the RS232 IN DB9 rear panel connector.
Assign a UNIT ID (1 to 63) to use the remote program.
Leave at, or set to, 0 if no remote access is desired.
Set the RS232 BAUD RATE to match the PC setting.
If you are familiar with the SCTeci or the Drake Software
Program, operation will be clear. If not familiar with them, see
further instructions in the insert provided with the CDROM or
stored on the CDROM, or the SCTeci instructions.

SERVICE INFORMATION
You may contact the R.L. DRAKE Service Department for
additional information or assistance by calling
+1 (937) 746-6990, Monday through Friday, between
8:00 A.M. and 4:00 P.M. Eastern Time, except on holidays.
You may also contact the R.L. DRAKE Service Department by
E-mail at the following address:
or by Telefax:
+1 (937) 806-1576.
Should you want to return your unit for service, package
the unit carefully using the original carton or other suitable
container.
Write your return address clearly on the shipping carton
and on an enclosed cover letter describing the service
required, symptoms or problems. Also include your
daytime telephone number and a copy of your proof of
purchase.
The unit will be serviced under the terms of the
R.L. DRAKE LLC Limited Warranty and returned
to you.
Red is an overnight service. Send the unit in a way that it
can be traced if we can’t verify receipt of shipment. We
suggest UPS or insured postal shipment.
If the unit is still under the original owner’s warranty,
R.L. DRAKE will pay the cost of the return shipment to
you. Our return shipping policy is that we will return it UPS
Brown if received Brown or by US Mail, it will be returned
Blue if received Blue or Red—or it will be returned
however you prefer if you furnish the return cost for the
method you select.
If the unit is out of warranty, use one of the following
methods for return shipment:
1) You designate billing to American Express, VISA,
MasterCard or Discover card;
2) You prepay the service charges with a personal check,
or
3) You specify some other method of return and payment.
When calling, the technician can estimate the repair
charges for you over the phone. This is another good
reason to call before sending a unit in for repair.
Typically, equipment is repaired in five to ten working days
after it arrives at R.L. DRAKE if we have all the facts. If we
must call you, it may take longer. R.L. DRAKE is not
responsible for damage caused by lightning, nonprofes-
sional alterations, “acts of God”, shipping damage, poor
storage/handling, etc. R.L. DRAKE will make note of any
shipping damage upon receipt.
You will need to send proof of purchase to receive
warranty service. Typically, a copy of the invoice from an
R.L. DRAKE dealer will suffice. The warranty is for the
original owner only and is not transferable.
IF YOU NEED TO CALL FOR HELP
Call our Customer Service/Technical Support line at
+1 (937) 746-6990 between 8:00 A.M. and 4:00 P.M.
Eastern Time, weekdays. Please have the unit’s serial
number available. We will also need to know the specifics
of any other equipment connected to the unit.
When calling, please have the unit up and running, near
the phone if possible. Our technician(s) will likely ask
certain questions to aid in diagnosis of the problem. Also,
have a voltmeter handy, if possible.
R.L. DRAKE also provides technical assistance by
e-mail: T[email protected]
or by Telefax: +1 (937) 806-1576.
Many of the products that are sent to us for repair are in
perfect working order when we receive them. For these
units, there is a standard checkout fee that you will be
charged. Please perform whatever steps are applicable
from the installation sections of the Owner's Manual
before calling or writing—this could save unnecessary
phone charges. Please do not return the unit without
contacting R.L. DRAKE first: it is preferred to help
troubleshoot the problem over the phone (or by mail) first,
saving you both time and money.
Inside the carton, enclose a note with your name, ad-
dress, daytime phone number, and a description of the
unit’s problem.
The unit must be sent to the following address:
Service Department
R.L. DRAKE LLC
230 Industrial Drive
Franklin, Ohio 45005 U.S.A.
Be sure to include your street address which will be
needed for UPS return. UPS Surface (Brown Label) takes
7-10 days to reach us depending on your location, Blue
takes 2-3 days.

Three Year Limited Warranty
R.L. DRAKE LLC warrants to the original purchaser this product shall be free from defects in material or workmanship
for three (3) years from the date of original purchase.
During the warranty period the R.L. DRAKE LLC or an authorized Drake service facility will provide, free of charge,
both parts and labor necessary to correct defects in material and workmanship. At its option,
R.L. DRAKE LLC may replace a defective unit.
To obtain such a warranty service, the original purchaser must:
(1) Retain invoice or original proof of purchase to establish the start of the warranty period.
(2) Notify the R.L. DRAKE LLC or the nearest authorized service facility, as soon as possible after discovery of a
possible defect, of:
(a) the model and serial number,
(b) the identity of the seller and the approximate date of purchase; and
(c) A detailed description of the problem, including details on the electrical connection to associated equipment and
the list of such equipment.
(3) Deliver the product to the R.L. DRAKE LLC or the nearest authorized service facility, or ship the same in its original
container or equivalent, fully insured and shipping charges prepaid.
Correct maintenance, repair, and use are important to obtain proper performance from this product. Therefore
carefully read the Instruction Manual. This warranty does not apply to any defect that R.L. DRAKE LLC determines
is due to:
(1) Improper maintenance or repair, including the installation of parts or accessories that do not conform to the quality
and specifications of the original parts.
(2) Misuse, abuse, neglect or improper installation.
(3) Accidental or intentional damage.
All implied warranties, if any, including warranties of merchantability and fitness for a particular purpose, terminate
three (3) years from the date of the original purchase.
The foregoing constitutes R.L. DRAKE LLC’S entire obligation with respect to this product, and the original purchaser
shall have no other remedy and no claim for incidental or consequential damages, losses or expenses. Some states
do not allow limitations on how long an implied warranty lasts or do not allow the exclusions or limitation of incidental
or consequential damages, so the above limitation and exclusion may not apply to you.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
This warranty shall be construed under the laws of Ohio.
