APPENDIX F: SERIAL PORT COMMANDS
55
Command Syntax
All command lines in this manual are set off by the flag symbol "
O
". The serial command line that follows the "
O
"
uses the following typographic conventions:
<X>
Parameters enclosed in "< >" indicate a mandatory parameter
[X]
Parameters enclosed in "[ ]" indicate an optional parameter.
1-8
Parmeters 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 number on G-Link network (valid combinations depend on connected devices: for
an AP400, device type is 3, device ID number 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. Note: Using the all-mic toggle may not produce the desired result, depending on the
state they are in. For example, if one mic is muted and all other mics are not, an all-mic toggle
would mute all others, but unmute that one mic.

sary) an example.
