5.2.7 End-of-Life Commands/Queries
Certain commands/queries are marked by Comtech EF Data as End-of-Life (EOL). Noted with an asterisk (*) in the Parameter Type
column (full details are available in Section 5.4), these commands are fully supported in this product, although Comtech
EF Data strongly recommends that you use the equivalent new commands for new implementations:
EOL-designated Command/Query (Page #)
CAA (5-12)
CUS (5-15)
DAT (5-15)
LNA (5-19)
RET (5-24)
RSN (5-29)
SFS (5-30)
TNA (5-32)
5.3 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.
5.3.1 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.
