Note: See
Polling Mode Data Flow Examples
in Appendix D for sample Polling Mode com-
munications scenarios.
Note: See
USB HID Interface
for protocol information relating to USB.
Definition:
These parameters only take effect for Polling Mode
<K140,5>
on the main
RS-232 or RS-422 ports (not on the Auxiliary 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
).
To enable multidrop protocol, the RS422 port must be enabled,
<K102,1>
,
in order to turn the transmitter on and off. If RS-232 is enabled instead of
RS422,
<K102,0>
, then Polling Mode will operate as a Point-to-Point poll-
ing protocol. This is because the RS-232 transmitter is always left on when
enabled.
