[SECTION]/Item Range Description
Use CTS Line: Yes or No This parameter specifies if the CTS modem control line is to
be used. If the parameter is set to No, the CTS line will not
be monitored. If the parameter is set to Yes, the CTS line will
be monitored and must be high before the module will send
data. Normally, this parameter is required when half-duplex
modems are used for communication (2-wire).
Response Timeout: 0 to
65535
This parameter represents the message response timeout
period in 1-ms increments. This is the time that a port
configured as a master will wait before re-transmitting a
command if no response is received from the addressed
slave. The value is set depending upon the communication
network used and the expected response time of the slowest
device on the network.
ACK Timeout 0 to
65535
DLE-ACK timeout in milliseconds.
Retry Count: 0 to 10 This parameter specifies the number of times a command
will be retried if it fails.
[DF1 Slave Port 0]
[DF1 Slave Port 1]
[DF1 Slave Port 2]
Enabled: Yes or No This flag specifies if the port on the module will be utilized. If
the parameter is set to No, the port will not be used. If the
parameter is set to Yes, the port will be used supporting the
DF1 protocol.
RS Interface 0, 1, or 2 0=RS-232, 1=RS-485, 2=RS-422
Protocol: Full or
Half
This parameter specifies the DF1 protocol to be used on the
port. Full Duplex or Half-Duplex
