MINI INTERFACE CONVERTERS
2.1 Description
These interface converters enable connection
between DTE and DCE data-communications
equipment with different interfaces. They operate
in synchronous applications (except for the
IC952A and IC953A, which operate in
asynchronous applications) at data rates up to
2048 kbps with balanced interface at both ends,
or at data rates up to 200 kbps with V.24/RS-232
at one end.
Mini Interface Converters perform both the
physical and electrical conversion between the two
interfaces. The circuitry is designed to provide
short-range interface conversion.
Most models operate without AC power, using
ultra-low power from the DTE and DCE
equipment data and control signals.

2.2 Available Models
IC954A-M
For converting between V.24/RS-232 and
V.36/RS-422 interfaces. The IC954A-M is switchselectable and is used either for connecting a
V.24/RS-232 DTE to a V.36/RS-422 DCE, or for
connecting a V.24 DCE to a V.35 DTE.
Installing the Converter is simple, since it plugs
directly into the DCE and DTE. Connect the
Converter directly to the RS-232/V.24 device, and
the cable connector to the RS-449 device. The
Converter comes factory strapped for RS-232
DTE/RS-449 DCE. To alternate this configuration:
1) Separate the two halves of the plastic cover by
pressing the marked places on the sides,
starting at the cable end.
2) Remove the 40-pin DTE/DCE socket by gently
grasping both sides and slowly moving it from
side to side.
3) Replace the socket so that the DCE faces the
RS-232 connector and the DTE faces the RS-449
device. Make sure that the pins are aligned with
the socket.
