3. General

The V.24/X.21 Interface Converter Model IC933A

connects and converts from V.24 DTE to X.21

DCE. Model IC944A connects and converts from

X.21 DTE to V.24 DCE. Users can take advantage

of high-speed trunk lines with X.21 interfaces and

still use existing V.24 multiplexers, modems, and

terminals. The compact, lightweight conversion

unit provides complete electrical and mechanical

conversion. It operates without mains power supply

by using ultra low power from the standard

RS-232C/V.24 data and control signal voltages.

4. Applications

Model IC933A installs between a V.24 terminal

or multiplexor and an X.21 modem and Model

IC944A installs between an X.21 terminal or

multiplexor and a V.24 modem. Figures 4-1

and 4-2 illustrate these applications.

5. Installation

5.1 Installing the V.24 DTE/X.21 DCE (IC933A) Model

To install the unit, simply plug its DB25 (male)

connector directly into the DB25 (female)

connector on the RS-232/V.24 device (DTE).

Attach the unit’s DB15 (male) connector to the

DB15 (female) connector on the X.21 device

(DCE).*

5.2 Installing the X.21 DTE/V.24 DCE (IC944A) Model

To install the unit, simply plug its DB15 (female)

connector into the DB15 (male) connector on the

X.21 device (DTE). Attach the unit’s DB25 (male)

connector to the DB25 (female) connector on the

V.24 device (DCE).*

*NOTE

If you need to change the gender of the unit’s connectors,

use gender changers or short cables. Do not use extreme

lengths of cable. Since the unit operates at low power,

using cables that are too long will affect the unit’s operation.
