APPENDIX E • SERIAL COMMANDS

General Text Command Form Description

The RS-232 serial port protocol is 9,600, 19,200, 38,400 (default),

or 57,600 baud; 8 bits, 1 stop bit, no parity.

The Type ID and Device ID have the following definitions:

Type ID Unit type Device ID

Range

Ox5 XAP 800 0x0 - 0x7, 0xff

0x4 PSR1212 0x0 - 0x7, 0xff

0x6 XAP TH2 0x0 - 0x7, 0xff

The XAP 800 accepts the commands outlined in the Serial

Commands table. The structure of serial commands is as follows:

# (indicates the start of a command line), Unit ID, Device ID,

Command, then any additional options in the order that they

appear in the command descriptions on the following pages.

Commands can be either UPPER CASE or lower case. Return

values are always in upper case. For a command to be

recognized by the serial port, the command must be terminated

by a carriage return.

For example, a command to disable mute for Mic 2 (input

channel 2) on XAP 800 device "0" would have the command line:

#50 MUTE 2 I 0. In this command line, 5=XAP 800, 0=unit 0,

MUTE=command, 2=channel 2, I=input channel, 0=off state.

If a command calls for a "null" value, leave a blank in the

command line (for example "#50 MUTE 2 I" would return the

current mute state of Mic 2 on device 50).

Designations

The following tables define the relationship between alpha and

numeric representations. Text commands use the alpha

designation and binary commands use the numeric. In addition,

different groups have different allowable channel ranges.
