Appendix F: Serial Commands

The AP800 accepts serial commands via the serial port; the commands are then channeled along the G-Link network to all interconnected AP products. The commands provide the same control as the LCD menu structure, plus several others. The following commands pertain only to the AP800.

RS-232 Serial Port Protocol 9,600 (default), 19,200 or 38,400 baud, 8 bits, 1 stop bit, no parity

The AP800 will accept the commands outlined in the AP800 Serial Commands table (see page 40). The structure of serial commands is as follows: “#” (which signifies the start of a command line), device ID, command, then any additional options in the order that they appear in the command descriptions on the following pages.

For example, a command to disable Automatic Gain Control for Mic 2 on AP800 device “0” would have the command line: #10 AGC 2 0. In this command line, 1=AP800, 0=unit 0, AGC=command, 2=mic channel, 0=off state). If a command calls for a “null” value, leave a blank in the command line (i.e. “#10 AGC 2” would return the current AGC state of Mic 2 on device 10).

Commands can be either uppercase or lowercase. Return values are always in uppercase. For a command to be recognized by the serial port, the command must be terminated by a carriage return.

Command syntax

The command line uses the following typographic conventions:

<X>

Parameters enclosed in “< >” indicate a mandatory

 

parameter

[X]

Parameters enclosed in “[ ]” indicate an optional parameter

1-8

Parameters separated by a “-” indicate a range between the

 

values

4,7,9

Parameters separated by a “,” indicate a list of available

 

values

MREF

Words in ALL CAPS bold indicate command text

[DEVICE]

Device type and ID on G-Link network. Valid combinations

 

depend on connected devices. For an AP800, device type is 1,

 

and device ID will always be 0–7. If omitted, the product that

 

first receives the command processes it.

*

Can be used to set a parameter on all microphone channels,

 

but it can’t be used to query all mic channels.
