In general, the point-to-point protocols
will work well in most applications. They require no address and
use RS-232 or RS-422 communications standards.
Definition:
Protocols define the sequence and format in
which information is transferred between the reader and the host,
or in the case of Multidrop, between the readers and a
concentrator.
Serial Cmd:
<K140,protocol,address>
Default:
Point-to-Point
Options:
0 = Point-to-Point
1 = Point-to-Point with RTS/CTS
2 = Point-to-Point with XON/XOFF
3 = Point-to-Point with RTS/CTS and
XON/XOFF
4 = ACK/NAK
5 = Polling Mode
Note: In all protocol modes, the preamble <K141> and postamble <K142> character strings can be used to frame the
decode data, and both are included in calculating the LRC Status (Longitudinal Redundancy Check).
