RS-232
DIFFERENCE:
MMX4x2-HDMI-USB20-L model is assembled with two local RS-232 ports. TPS port can be
found on MMX4x2-HT200 model only.
RS-232 tab in Control menu
The following settings and functions are available (both on local and TPS serial ports):
▪
Operation mode: Control, Command Injection, or Disconnected (for more details about serial interface
modes see the
section);
▪
Baud rate: 4800, 7200, 9600, 14400, 19200, 38400, 57600, 115200;
▪
Data bits: 8 or 9;
▪
Parity: None, Odd, or Even;
▪
Stop bits: 1, 1.5, or 2;
▪
Command injection: enable or disable; port number;
#commandinjection
▪
Control protocol: LW2 or LW3;
#protocol
#rs232 #rs-232 #serial
▪
Message sending via serial port;
#message
▪
Reloading factory defaults (see factory default settings in the
section).
ATTENTION!
If the matrix is connected to a TPS2 output board of a matrix frame, the RS-232 configuration
settings (baud rate, data bits, etc..) will not be changeable on the matrix side.
RS-232 Message Sending
The message in the field can be sent out via the
current RS-232 port. Response cannot be seen in
the surface.
ATTENTION!
The escaping is done automatically when sending a message via this surface. When the
message is an LW3 command, it has to be closed by Carriage return and Line feed, e.g.: CALL /MEDIA/
VIDEO/XP:switch(I1:O1)\x0d\x0a.
RS-232 Message Recognizer
DIFFERENCE:
This feature is available from firmware
v1.3.1.
This tool can be used to recognize messages coming
from the RS-232 port. The message can be used as a
Condition in Event manager and an Action can be defined
for it.
Definitions
Delimiter sequence (hex):
Each message is closed by this
separator (if defined).
Accept timeout (ms):
When the set time has passed after the
last received message and delimiter was not detected,
the device saves the data into the Text, Hex, and Hash
properties. The timeout setting is useful if there is no
special or easily defined delimiter in the incoming data,
but there is a time gap between the messages.
Text:
The recognized message in ASCII-format.
Hex:
The recognized message in hex format.
Hash:
Binary data that is mapped from the original
message. The length of the hash is shorter, and the same
message results in the same hash.
Working Method
A message gets recognized from the incoming data if one of the following occurs:
▪
The set DelimiterHex is detected in the message, or
▪
The set TimeOut has passed since receiving the last data bit.
