15.3 RAW TCP gateway
15.3.1 Raw client gateway
The RAW client gateway can be used if a serial “master” device has to send requests to one slave device
(also called server) located on the IP network.
The server can be either an ETIC gateway or a PC including a software TCP server.
 Select the “transparent” and then the “raw client COM1” or the “raw client COM2” menu .

Enable the raw client 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 packet”
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 the time the gateway will wait before disconnecting the TCP link if no characters are detected.
“TCP port number”
parameter :
Set the port number the gateway has to use.
If the Raw TCP client gateway is assigned to both serial COM ports, the TCP port numbers must be different
on each port.
“Raw server IP address” parameter :
The raw client gateway is able to communicate with a raw server gateway.
Assign an IP address to define the destination gateway.
