Commands
Table 13. AP10 Serial Commands
Command Function Command Function
AA Auto-answer RING Ring acknowledgement
DIAL Dial touch-tones TE Control/report the connect state of the unit
HOOK Send hook-flash to the line TERL Return telephone ERL
LVL Return transmit/receive level TERLE Return telephone ERLE
MUTE Control/report mute status* UID Return unit identification number
NULL Renulls AP10 to telephone line VER Return current version of software
* Applied to a specific channel
The AP products accept serial commands via the AP800’s serial port; the commands
are then channeled along the G-Link network to all interconnected AP products. In
the case of the AP10, the commands provide the same control as the front-panel
controls, plus several others. The following commands pertain only to the AP10.
AP800 RS232 Serial Port Default Protocol (9,600 (default), 19,200 or 38,400 baud, 8 bits, 1 stop bit, no parity)
The AP10, via custom controller, will issue DTMF tones in the form of telephone-keypad digits (0–9), the * and # keys
(for dialing and accessing voice-mail/pager). Also via custom controller, the AP10 will accept serial commands outlined
in Table 13 (below).
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 enable auto-answer on AP10 device “0” would have the command line: #20 AA 1. In this
command line, 2=AP10, 0=unit 0, AA=command, 1=on state). If a command calls for a “null” value, leave a blank in
the command line (i.e. “#20 AA” would return the current state of auto-answer on device 20). Commands can be either
UPPER CASE or lower case. Return values are always in upper case. In order for a command to be recognized by the
serial port, the command must be terminated by a carriage return.
Command Syntax
All command lines will be 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 Parameters separated by a “-” indicate a range between the values
4,7,9 Parameters separated by a “,” indicate a list of available values
AA Words in ALL CAPS bold indicate command text
<DEVICE> Device type/number on G-Link network (valid combinations depend on connected devices:
for an AP10, device type is 2, device number will always be 0–9, A–F, where A=10 and
F=15). See Table 1, Device ID Dip Switch Settings (Page 6).
The command string will then be explained (where necessary), followed by the returned values and (where necessary)
an example.
