TELNET
[IP address]
[Listen Port]
eg. TELNET 192.168.0.155 23 where the
IP address
is 192.168.0.155 and
Listen Port
is 23.
Enable RS-232 PPP Server
Check this box to enable the PPP network serv-
er on the RS-232 port.
Enable RS-485 Serial Gateway
Check this box to enable the Serial Gateway
Server on the RS-485 port.
Data Rate
The serial data rate desired. Serial data rates
available range from 110bps to a maximum of
38,400 b/s.
Data Bits Parity Stop Bits
The data format desired. Data formats of 8N1,
7E1, 7O1, 7E2, 7O2 are supported.
Character Timeout
Enter the maximum delay (in msec) between
received serial characters before packet is sent
via network.
Server
When configured as Server, the module will wait
for a connection to be initiated by a remote cli-
ent
Listen Port
Server Only. Enter the TCP port number on
which the server must listen for incoming con-
nections. The standard TELNET port is 23.
Client
When configured as Client, the module will
automatically attempt to connect to the specified
remote server
Remote Device Port
Client only. Enter the TCP port number of the
remote server (i.e. the remote port to automati-
cally connect to).
Remote Device IP Address
Client only. Enter the IP Address of the remote
server (i.e. the remote IP Address to automati-
cally connect to).
3.12.3 Modbus TCP to RTU Server
The Modbus TCP to RTU Server allows an Ethernet Modbus/TCP Client (Master) to
communicate with a serial Modbus RTU Slave. The RM-90 makes this possible by internal-
ly performing the necessary protocol conversion. The conversion is always performed by
the RM-90 which is directly connected to the Modbus serial device (i.e. only this module
needs to have Modbus TCP to RTU Server enabled).
