Appendix E. Remote Command API
Introduction
This document describes the serial and network control commands for the Datasat RS20i Audio
Processor. The RS20i 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 RS20i
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 RS20i. To configure the serial port on the RS20i, go to the menu System ->
Automation ->Serial. Select the desired baud rate, and data bits should be 8. Also set Serial
Command Mode to RS20i.
For test purposes you may connect to the RS20i using PuTTY or any similar serial
communications program. Connection from a standard PC to the RS20i 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 RS20i
The RJ45 connector labeled Ethernet on the back of the RS20i can be connected to a network
switch or router. Once the network parameters are properly set the IP address for the RS20i can
be found in the Network screen in the IP Address box.
The RS20i could 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 RS20i IP address at TCP port 14500.
Once connected the client may send commands as described in this document to set or read
the RS20i configuration. The configuration changes happen as soon as they are received. For
example, you should see the volume change immediately after receiving a command to set the
volume.
For test purposes you may use PuTTY or any similar communications program to make a
TCP/IP connection to the RS20i.
Using PuTTY
Open PuTTY in the configuration Session and set the following:
Host Name: (enter the RS20i 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.
