About Address Terminology
A “row” or row letter refers to a six-output array, either the internal Cat 5 outputs on the AVX-562 or an 1176
expander. The AVX-562 row is always addressed “A” and other 1176 expanders should be addressed in order
as shown above. “Column” refers to the zone number as labeled on the AVAtrix or 1176 expander.
General Commands (Abbreviated)
These commands can be used at any time during
operation of the AVAtrix to change the state of selected
settings. NOTE: Alpha characters are not case-sensi-
tive. ASCII codes not specified are ignored (i.e. control
codes, unused alphanumeric characters, etc.).
Source Selection Commands (Abbreviated)
Assign or change input sources to the AVAtrix main (local) output, any individual Cat 5 zone output, zone
groups, or all zones. In the “Command” column below, actual commands are shown in upper case, and vari-
ables are represented by lower case bold characters (commands are not case-sensitive).

Appendix D: RS-232 Serial Protocols
Model AVX-562, and 1176 expanders can be controlled via RS-232 from a PC or dedicated controller. Two dif-
ferent RS-232 serial protocols are available; the Abbreviated Command Set is simple, and one-way, and the
Extended Command Set has more commands and reports all system changes through the serial port, regard-
less of the origin of the command. Use commands from either or both protocols.
Specifications
The RS-232 control port on the AVAtrix is fixed at 9600 baud. There
is no provision for flow control (XON/XOFF, DTR, etc.). On power
up, the AVAtrix echoes any received character, but that echo function
may be turned off as described at the end of this section to prevent
corruption of replies.
