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no liability for losses incurred as a result of out-of-date or incorrect information contained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.
