4.0 GENERAL

The standard Up/Dn Converter is controlled via a rear panel serial link (RS-422/485)(Reconfigurable to RS-232). With the front panel control, a user can operate the L-Band Up/Dn Converter from its front panel as well as from the serial link. This section describes the format for the ASCII serial control as well as front panel operation.

Note: Some commands and status strings have been changed as of Software Release v7.70 (main board) and v5.20 (front panel). Units marked with “Rev A” on the rear panel support the new protocol.

4.1 LT-3600 SERIAL INTERFACE

The serial interface format to the Up/Dn Converter for RS-422 is identical to the RS-485 format except that under RS-485, the format includes an address field (aa in the format below).

4.2 COMMUNICATION PROTOCOL

Baud Rate: 9600

Parity: None

Data Bits: Eight

Start Bits: One

Stop Bits: One

4.2.1General Data Format

{aaCND…}

Where:

{= Start byte

aa= 2 character address (00 to 50, remote interface only)

C = 1 character, either C (Command) or S (Status)

N = 1 number 0 to 9, A,B,C Command or Status Number

D = 1 or more Data characters (depending on command)

} = Stop byte

Note: The address is only used in the RS-485 mode when having several addressable units communicating with one station.
