8-33 Parity / Stop Bits
Option: Function:
[1] Odd Parity, 1 Stop Bit
[2] No Parity, 1 Stop Bit
[3] No Parity, 2 Stop Bits
8-35 Minimum Response Delay
Range: Function:
0.01 s
*
[0.0010 - 0.5 s] Specify the minimum delay time
between receiving a request and
transmitting a response. This is used for
overcoming modem turnaround delays.
8-36 Maximum Response Delay
Range: Function:
Size related
*
[0.1 - 10.0
s] Specify the maximum permissible
delay time between receiving a
request and transmitting the response.
If this time is exceeded, no response
will be returned.
8-37 Maximum Inter-char delay
Range: Function:
0.025 s
*
[0.025 - 0.025
s] Specify the maximum delay time
between 2 characters in a message.
Exceeding this delay time will cause the
message to be discarded.
