Port:
The TCP port that GTOR will listen to.
Request Type:
The type of MODBUS queries that are sent to the GTOR over the GPRS network is
determined by this field.
“MODBUS TCP”, “MODBUS RTU over TCP” and “MODBUS ASCII over TCP” protocols are
selected.
Response Type:
The type of MODBUS responses to the GTOR via the serial link is determined by this
field. One of the “MODBUS RTU” and “MODBUS ASCII” protocols is selected.
Request Timeout:
In server mode, if a new query does not arrive in GTOR until the query “timeout”
expires, the GTOR will close the TCP connection with the sending machine and
allocate resources for new TCP connections.
If the time between two queries is greater than the timeout expired on the query
side, a new TCP connection must be opened before the query is sent.
