Section 7. REMOTE CONFIGURATION
7.1 INTRODUCTION
An IMUX 2000 multiplexer can be set up and monitored from a controller connected to its RS-232
remote port. The controller, which may be a simple video display terminal, a personal computer (PC),
or another type of computer system, can be connected locally using a cable or remotely using dial-up
modems over a data network. The terminal or computer used for this purpose must contain a basic
communications program which provides call setup and terminal emulation functions.
IMUX 2000 multiplexers operate strictly in the command-response mode. That is, a multiplexer
generates a message only in response to a received command.
The Simple Command Language (SCL) provides the basis for communication between the user and
the multiplexer. The operator types SCL commands at the keyboard and views the responses on the
terminal screen. The design of the SCL command structure also allows IMUX 2000 multiplexers to be
integrated into a multi-node, multi-vendor network controlled by an automated Network Management
System (NMS).
7.2 HARDWARE AND PROTOCOL ISSUES
7.2.1 REMOTE PORT
Each CM4 Common Module has one remote port. A terminal multiplexer therefore has one remote
port while a drop/insert multiplexer has two remote ports. IMUX 2000 remote ports are RS-232C
compatible, asynchronous, serial interfaces which can operate at baud rates from 110 bps to 57.6 Kbps.
The remote port on each CM4 module is equipped with a 9-pin male (DB-9) connector, which is
located on the MA-270R Module Adapter or Optical Interface Adapter (OIA) associated with that
module. Instructions on setting remote port baud rate and parity appear in Paragraph 5.13 of this
manual. The pin assignments for the remote connector appear in Section 2 of this manual.
