The RS232 port can be configured as follows:
TCP/IP to IR bridge
In this mode the IR Commander Matrix will send any data received on the RS232 port out via TCP on port 9761. The port can be changed via the web page.
Select RS232 to TCP bridge baud rate. As it says, if you wish to use the RS232 interface you can choose the required baud rate - default is 9600.
It can operate in 2 modes client and server.
When the unit is a server it does not need to know the IP address of the client. The client initiates the transaction and from then on data is sent to the IP address of the client.
When the unit is a Client it must have an IP address to send to as it is the one that initiates the service.
The IP of the Server can be entered into the IP address box, or if there is another MATRIX module on the network and that is a server, check the find server box and the two will find each other. The IP address box and MAC address will be filled in once they have found each other. (About 1 minute) You will need to refresh the page to see them.
The Bridge will operate at all of the baud rates. If you are not using the on board IR receiver make sure it is switched off (via the main options page). If unwanted IR noise is detected it can generate interrupts that might cause dropped characters.
RS232 accesses stored IR codes
This simply allows access to the 128 stored IR codes via RS232. Useful for legacy Crestron systems etc. Send KRS followed by a 3 digit decimal number representing the location you want to address. The string should be terminated by a Carriage return and line feed Cr Lf (chars 13 and 10)
For example: KRS002CrLf
This will cause the contents of memory location 002 to be blasted via the IR emitters.
Note - the CrLf is just 2 characters char(10) and char(13)
Note - this mode will not operate a CTX35 as the connection is in use. Any location containing CTX35 codes will do nothing.

RS232 is disabled
Note - if RS232 is not being used it should be switched off as it also uses interrupts and can use up processor time
