MX-FR Series Modular Matrix Frames – User's Manual 143
RS-232 over TPS Commands
INFO:
ATTENTION! If the endpoint (the controlled device) sends more than 54 bytes at once without at least
100ms break between the data packets then the sent data could be lost.
Important Notices
▪ Maximum 128 bytes of data can be sent and 64 bytes of data can be received at once.
▪ There are two methods for sending data: ASCII and binary modes.
▪ The data rate can be 9600, 14400, 19200, 38400, 57600 baud. The number of the stop bit(s) and the
parity can be set up as well.
▪ If the TPS link operation is HDBaseT (and not long reach) mode and if there is no video signal
transmission, then the link can only operate on 9600 baud data rate.
▪ The communication parameters are not detected automatically, so the right values must be set for
both the input and the output boards.
Sending Data in Text Format
Command and Response
ȩ {:S#@<S><ascii_text>}
Ȩ No response from the matrix
Example
ȩ {:s#9@so=Blind text\r\n}
Ȩ No response from the matrix
CrLf is sent out on the 9th output. The matrix does not respond. If the remote controlled
device responds, the matrix is able to receive and show it.
Parameters
Parameter Description Parameter Values
<in2out2> Input or output port number Output number in 1- or 2-digit ASCII format (01, 3, 04 etc.)
<> Input or output port type I = input, O = output
<ascii_text> ASCII text Text to be sent
Important Notices about the Escape Characters
The text may contain any characters except '{' and '}', which are used for command framing. The following
escape sequences are supported: \r (carriage return); \n (new line); \t (bs); \x [hex code].
Example
Send the {power on}\r\n string to the second output:
ȩ {:S#2@SO=\x7Bpower on\x7D\r\n}
It is possible to send the real characters (new line-carriage return) instead of \r\n, but curly brackets must
be escaped. Other characters can also be escaped if it is preferred:
ȩ {:S#1@SO=\x7Bpower\x20on\x7D\r\n}
Sending Data in Binary Format
Command and Response
ȩ {:B#<in2out2>@<S><hex_string>}
Ȩ No response by the matrix
Example
ȩ {:b#9@so=0d0aad}
Ȩ No response by the matrix
‘0D 0A AD is sent out on the 9th output. The matrix does not respond. If the remote controlled device
responds, the matrix is able to receive and show it.
Parameters
Parameter Description Parameter Values
<in2out2> Input or output port number Output number in 1- or 2-digit ASCII format (01, 3, 04 etc.)
<> Input or output port type I = input, O = output
<hex_string> HEX string String to be sent
Every 2 characters represent a hexadecimal code. The maximum length of the data is 64 characters, so the
Receiving Data from the Far Endpoint
Every port can operate either in ASCII or Binary mode. The mode can be set up with the :SERIAL command,
see the next section. Depending on the selected mode, different messages are sent by the router when it
receives data from the far endpoint. These messages arrive from the router asynchronously without any
query command. (The router sends out the message immediately when the data is received). Thus, it may
happen that the message is inserted between another command from the controller and the response from
the router. The controller must be able to handle this case. For example, a simple switch:
▪ Controller:
▪ Router
▪ Router:
