Introduction
This manual describes the setup and installation procedures for the Intraplex Products DA-191B
Four-Port Asynchronous Data Module, Rev. A and above. Experienced users may refer directly
to the tables in Section 2 for configuration data.
Additional information about this system is contained in your Intraplex multiplexer operation
manual.
The DA-191B is a four-port data module, designed for use in the Intraplex Terminal and
Drop/Insert Multiplexers. The module provides transmission of one to four asynchronous data
channels over T1, E1 and other digital communications facilities, with either an RS-232C or an
RS-449 data interface.
The maximum data rate is 38.4 kbps for one-, two-, or four-channel operation. The module uses
one to eight time slots depending on the number of channels used and the data rates of the
channels being transmitted.
User-adjustable switches allow configuration of several parameters:
Maximum data rate
Time slot use
Transmit/receive direction for drop and insert operation
T1 or E1 (2 Mbps) system compatibility
Starting time slot selection
Data loopback for testing
Local or remote control access
Remote control access address
