PUBLICATION NOTICE
This manual has been compiled and checked for accuracy. The information in this manual
does not constitute a warranty of performance. Patton reserves the right to revise this
publication and make changes from time to time in the content thereof. Patton assumes
no liability for losses incurred as a result of out-of-date or incorrect information contained
in this manual.
RADIO AND TV INTERFERENCE
The Patton devices generate and use radio frequency energy, and if not installed and
used properly—that is, in strict accordance with the manufacturer’s instructions—may
cause interference to radio and television reception. The Patton devices have been
tested and found to comply with the limits for Class A computing devices in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are designed to
provide reasonable protection from such interference in a commercial installation.
However, there is no guarantee that interference will not occur in a particular installation.
If the Patton devices do cause interference to radio or television reception, which can be
determined by disconnecting the cables, the user is encouraged to try to correct the
interference by one or more of the following measures: moving the computing equipment
away from the receiver, re-orienting the receiving antenna, and/or plugging the receiving
equipment into a different AC outlet (such that the computing equipment and receiver are
on different branches).
Canadian EMISSIONS
This digital apparatus does not exceed the Class A limits for noise emissions from a
digital apparatus set out in the Radio Interference Regulations of the Canadian Department
of Communications.
Le present appareil numerique n’emet pas de bruits redioelectriques depassant les limites
applicables aux appareils numeriques de la Class A prescites dans le Reglement sur le
brouillage redioelectrique edicte par le ministere des Communications du Canada.

CHAPTER 1 - Operation
The Patton 2021P (CTS TCB-V.24/X.21) is an EIA RS-232 to CCITT X.21
interface converter with a built in tail circuit buffer, allowing modem to
modem interconnection. The interface converter operates bi-directionally.
DCE / DTE selection of each port permits interfacing an RS-232 terminal or
modem to an X.21 terminal or modem. This interface converter can satisfy
all interface conversion requirements. This adapter is ideal for High Speed
Modems since it can operate at up to 128Kbps. Connection of two terminal
devices is not supported because internal clocking is not provided by this
device.
Devices can be separated up to 4000 feet away from the interface con-
verter on the balanced interface side and RS-232 devices can be separated
up to 50 feet away from the interface converter. The unit is supplied with a
female DB-25 for the RS-232 port and a female DB-15 for the CCITT X.21
port.
The interface converter is housed in a sturdy aluminum enclosure and has
an internal 110/220VAC switch selectable power supply. Sixteen of the
interface converters will also fit into the MCS-16 card rack for convenient
data center applications.
The unit can operate on standard power found in most countries.

CHAPTER 2 - SETUP AND INSTALLATION
Installation
Set the switches to match the required configurations based on the
diagrams below. The cabling between each device and the interface
converter must be terminated with male connectors. J1 is the RS-232 /
V.24 interface and J2 is the X.21 interface. The IEC connector is provided
to interface to the power plug required in the country of use. Insure the
110/220VAC switch is set correctly for the line voltage in use prior to
applying power to the interface converter.
Selection of DTE/DCE
To connect an RS-232 terminal type device (DTE) to an X.21 Modem type
device (DCE), connect the terminal to J1 and the Modem to J2. Move
SW1 and SW2 to the DCE position, and SW3, SW4 and SW5 to the DTE
position, as shown in Fig. 1.

Equipment Grounding
JP4 provides grounding interconnection in those systems requiring a
connection between Frame Ground and Signal Ground. If signal ground
and chassis ground interconnection is desired, install the jumper on JP4.
LED Indicators
The Following LED indicators are provided for diagnostics: Power, Transmit
Data (T), Receive Data (R), Control (C), Indicate (I) and Signal Timing (S).
Factory Test Straps
The Factory Test Straps JP1, JP2 and JP3 must be installed for proper
operation of the interface converter.
Signal Crossover
JP5 controls selection of DTR or RTS as the active V.24 control signal.
JP6 controls selection of the DCD or CTS as the active V.24 control signal.
The selection of DTE or DCE on the two interfaces will determine which
X.21 signal is connected to which V.24 control signal.
