The ModBus TCP to RTU Server may be configured to operate on either the RS-232 or RS-485
port. It does not support operation on both ports at the same time.
Enable RS-232 ModBus
TCP to RTU Gateway
Check this box to enable the ModBus TCP to RTU Server on the RS-
232 port. Only a single serial port is allowed at a time.
Enable RS-485 ModBus
TCP to RTU Gateway
Check this box to enable the ModBus TCP to RTU Server on the RS-
485 port. Only a single serial port is allowed at a time.
Data Rate The serial data rate desired. Serial data rates available range from
110bps to a maximum of 38,400 bps.
Data Bits Parity Stop Bits The data format desired. Data formats of 8N1, 7E1, 7O1, 7E2, 7O2 are
supported.
Pause Between Requests Enter the delay between serial request retries in milliseconds.
Response Timeout Enter the serial response timeout in milliseconds – a serial retry will be
sent if a response is not received within this timeout.
Connection Timeout Enter the TCP connection timeout in seconds – if no ModBus/TCP data
