may need to delay sending a message after activating an
RTS (request to send) signal. Valid range is 0-65535.
Pre-send Time Delay
(x 1 ms)
If the Control Line is set to No Handshaking or Full Duplex,
this parameter is the amount of time the Master delays its
transmission after having received the last character from a
slave.
If the Control Line is set to Half-Duplex Without Constant
Carrier, then this parameter the amount of time between the
Master receiving the last character from a slave and
asserting RTS prior to transmitting.
Normal Polling Range Enter the low and high addresses to set the range for
normal polling when the Polling Mode is set to Standard.
Valid addresses are from 0 to 254. If you set the Low
parameter greater than the High parameter, that polling
range is disabled.
Normal Poll Group Size Enter the number of nodes in the normal polling group. This
