Appendix H: AP25 Remote Command API
Introduction
This document describes the serial and network control commands for the Datasat AP25 Audio Processors.
The AP25 supports a command set for remote control and automation. These commands can be transmitted via
either the Ethernet or the serial interface.
This document is intended to be used by any system integrator who needs to control the AP25 remotely.
Example of an application where these commands could be used may be an automation unit, a remote control
unit, or a remote software interface.
It assumes that the reader is familiar with standard serial and network TCP/IP concepts.
Serial Control
The remote serial control device must be connected to the RS232 ”Control” connector on the back of the
AP25. To configure the serial port, go to the menu System -> Automation ->Serial. Select the desired baud
rate. Also set Serial Command Mode to AP20.
For test purposes you may connect to the AP25 using PuTTY or any similar serial communications program.
Connection from a standard PC to the AP25 is a straight-through cable.
Once the serial connection is made and setup the user can execute any of the commands listed within this
document.
Ethernet connection to AP25
The RJ45 connector labeled Ethernet on the back of the AP25 can be connected to a network switch or router.
Once the network parameters are properly set the IP addresses for the AP25 can be found in the Network
screen in the IP Address box.
The AP25 may also be connected directly to another network device using crossover cable, or a straight cable
if the device supports auto-MDIX.
The client initiates the communication session with the AP25 IP address at port 14500. Once connected the
client may send commands as described in this document to set or read the AP25 configuration. The
configuration changes happen as soon as they are received. For example, you should see the Fader volume
change immediately after receiving a command to set the fader.
For test purposes you may use PuTTY or any similar communications program to make a TCP/IP connection
to the AP25.
Using PuTTY
Open PuTTY in the configuration Session and set the following: Host Name: (enter the AP25 IP address)
Port: 14500 Configuration type: Raw. Select the Open button. Once the network connection is made the user
may type in commands listed within this document and read the response.
Using HyperTerminal
In HyperTerminal, select “Connect Using: TCP/IP (WinSock). Then enter the AP25 IP address under “Host
address:”, and 14500 for “Port number: ”.
Using Telnet
To use Telnet, enter the IP address and port number in the command line, for example:
# telnet 10.1.1.78 14500
