communication
scenarios.
Definition:
These parameters only take effect for
Polling Mode
<K140,5>
on the main
RS-232 port and are completely independent of the
ACK/NAK Options
<K147>
.
The values of protocol characters can be changed, but the protocol events
cannot be disabled. The polling mode address is configured in the
<K140>
command (see
Poll Address
).
If RS-232 is enabled,
<K102,0>
,
Polling Mode
will operate as a
Point-to-
Point
polling protocol. This is because the RS-232 transmitter is always left
on when enabled.
