21.2.2 Raw server gateway
That gateway can be used if a serial slave device has to answer requests coming from devices
located on the IP network and acting like a master (also called TCP client).
• Select the “transparent” and then the “raw server COM1” or the “raw server COM2” menu.
• Enable the raw server gateway and set up the parameters as follows :
“RS232/485 input buffer size” parameter :
Set up the maximum length of an asynchronous string the gateway will store before transmitting it to
the IP network.
“Timeout of RS232/485 end of frame” parameter :
Set up the delay the gateway will wait before declaring complete a string received from the
asynchronous device.
Once declared complete, the gateway will transmit the string to the IP network.
“TCP inactivity Timeout” parameter :
Set up the time the gateway will wait before disconnecting the TCP link if no characters are detected.
“TCP port number” parameters :
Set up the port number the gateway has to use.
If the Raw TCP server gateway is assigned to both serial COM ports, the TCP port numbers must be
different on each port.
