The following is an overview of the parameters contained in the Settings– Port1 Settings section:
Item
Description
Default
Interface Settings
Interface
This parameter is used to set the interface mode (Loopback, RS-232,
RS-422 or RS-485) of serial port for the tGW-718i-D only.
Loopback: the internal loopback is used to self-testing.
RS-232
Pull-High/Low Resister
This parameter is used to enable or disable pull-high/low resister
for RS-485 or RS-422 of the tGW-718i-D only (1K Ohm).
Disable
Terminal Resister
This parameter is used to enable or disable terminal resister for
RS-485 or RS-422 of t the tGW-718i-D only (120 Ohm).
Disable
Port Settings
Baud Rate (bps)
This parameter is used to set the Baud Rate for the COM ports.
115200
Data Size (bits)
This parameter is used to set the Data Size for the COM ports.
8
Parity
This parameter is used to set the Parity for the COM ports.
None
Stop Bits (bits)
This parameter is used to set the Stop Bits for the COM ports.
1
Flow Control
This parameter is used to enable or disable hardware flow control
(CTS/RTS) function for the tGW-712, tGW-722, tGW-724,
GW-2212i, GW-2222i and GW-2232i only.
None
Remove Errors
Clear the Rx FIFO when the Parity、Framing、Break Error occurs.

Modbus Settings
Slave Timeout (ms)
This parameter is used to set the waiting time that should elapse after
last character of the request sent to the device before the timeout is
activated. The tGW-700/GW-2200 will report a 0x0B exception code if
there is no response from the slave device before the timeout period
expires, or will report a 0x4B exception code if the slave device is still
sending data when the timeout is activated.
The Slave T imeout value must be set to less than the response
timeout configured in the client software.
