5.2.3 [IEC-870-5-101 Master Port x]
Baud Rate
This parameter specifies the baud rate to be used on the communication channel
(port). Values from 110 to 38.4K are permitted.
Parity
None, Odd, Even
This parameter specifies the parity for this port using the following code
definitions: N=none, O=odd, E=even.
RTS On
0 to 65535
The parameter sets the RTS pre-send delay. The value entered represents the
number of milliseconds the module will wait after setting the RTS modem line
before sending the data.
RTS Off
1 to 65535
This parameter sets the RTS off delay. The value entered represents the number
of milliseconds the module will wait after the data packet is sent before dropping
the RTS modem line.
Minimum Delay
1 to 65535
This parameter specifies the minimum number of milliseconds to delay before
sending the message (setting RTS high). This can be used when the serial
network requires time for units to turn off their transmitters.
Receive Timeout
1 to 65535
This value represents the number of milliseconds to wait on a port from the time
the first character is received until the last character in the longest message
received on the port. This parameter should be set dependent on the baud rate.
A value of 2000 should work with most applications.
Single Char ACK F0, 1 or 3
Yes or No
If set to Y, a single character ACK (0xE5) will be sent instead of a fixed length
ACK (secondary function code 0) in response to a primary link function code 0, 1
or 3 if there is no access demand for class 1 data (ACD=1). If set to N, the fixed
length ACK will be sent.
