RS-232 data transmission runs three different interface: #rs-232#rs232#commandinjection
▪ P1, P1 channels are for bidirectional RS-232 communication. Disconnected, Control and Command
Injection operation modes are available.
▪ P2, P3
This port is able to transmit a unidirectional data flow, for example forwarding the serial messages or
Infra messages, which come from the Control Ethernet port (in this case the operation mode is always
Command Injection). Sending serial or infra message is also possible.
▪ TPS channels* are able to send and receive serial data, so P4-P10 ports can operate in Disconnected,
Control and Command Injection mode.
*In MMX8x4-HT400MC and MMX8x4-HT420M models.
The following settings and functions are also available:
▪ 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 port number;
▪ #protocol
▪ Message sending #message
▪ Reloading factory defaults (see the Factory Default Settings section).
RS-232 Message Sending
current RS-232 port. Response cannot be seen in
the surface.
ATTENTION!
RS-232 Message Recognizer
from the RS-232 port. The message can be used as a
Delimiter sequence (hex): Each message is closed by this
Accept timeout (ms):
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
but there is a time gap between the messages.
Text:
Hex:
Hash: Binary data that is mapped from the original
message. The length of the hash is shorter, and the same
message results the same hash.
Working Method
of the following occurs:
▪ The set DelimiterHex is detected in the message, or
▪ The set TimeOut has been elapsed since receiving the last data bit.
