Chapter 10. SERIAL REMOTE CONTROL

10.1 Overview

Serial-based remote management of Comtech EF Data's SLM-5650A Satellite Modem is available using the rear panel 9-pin 'J10
REMOTE' port. This chapter summarizes key parameters and procedures and their associated remote commands and queries, and
provides detailed instructions for use of the serial remote interface.
Make sure to operate the SLM-5650A with its latest available firmware.

10.2 Remote Control Protocol and Structure

The electrical interface is either an EIA-232 connection (for the control of a single device) or an EIA-485 multi-drop bus (for the control of many
devices). Data is transmitted in asynchronous serial form using ASCII characters. Control and status information is transmitted in packets of
variable length in accordance with the structure and protocol defined in this chapter.
10.2.1 EIA-232
This is a simple configuration in which the Controller device is connected directly to the Target via a two-wire-plus-ground connection.
Controller-to-Target data is carried, via EIA-232 electrical levels, on one conductor, and Target-to-Controller data is carried in the other
direction on the other conductor.
