Description
Data Bits:
5 to 8
This parameter sets the number of data bits for each
word used by the protocol.
Stop Bits:
1 or 2
This parameter sets the number of stop bits for each
data value sent.
RTS On:
0 to 65535 This parameter sets the number of milliseconds to
delay after RTS is asserted before the data is
transmitted.
RTS Off:
0 to 65535 This parameter sets the number of milliseconds to
delay after the last byte of data is sent before the RTS
modem signal will be set low.
Use CTS Line:
Y or N
This parameter specifies if the CTS modem control line
is to be used. If the parameter is set to N, the CTS line
will not be monitored. If the parameter is set to Y, the
CTS line is monitored and must be high before the
module sends data. Normally, this parameter is
required when half-duplex modems are used for
communication (2-wire).
Retry Count:
0 to 10
This parameter specifies the number of attempts for
each response message. If a message fails, it is retried
up to the count specified.
Request Timeout:
0 to 65535 This parameter specifies the number of milliseconds to
wait for a complete request message. The timer is
started after the DLE-STX character sequence is
received for the full-duplex protocol or the DLE-SOH
sequence for the half-duplex protocol. If the timer
expires, the current request message is aborted.
Busy Timeout:
0 to 65535 This parameter specifies the number of milliseconds to
wait for the pass-through port to become available.
ACK Timeout:
0 to 65535 This parameter specifies the number of milliseconds to
wait for a DLE-ACK character sequence after a
response is issued.

Command Delay:
0 to 65535 This parameter specifies the number of milliseconds to
wait between the initial issuance of a command. This
parameter can be used to delay all commands sent to
slaves to avoid "flooding" commands on the network.
This parameter does not affect retries of a command as
they will be issued when failure is recognized.
Response
Timeout:
0 to 65535 This parameter represents the message response
timeout period in 1-ms increments. This is the time that
a client waits 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.
Retry Count:
0 to 10
This parameter specifies the number of times a
command is retried if it fails.
