RS-232 is an industry standard. RS-422 is
used when greater cable lengths are required and/or where noise
interference is an issue.
Definition:
RS-422, if enabled, allows communication
through RS-422 I/O lines.
When RS-422 is enabled, RS-232 is
disabled.
When RS-422 is disabled, RS-232 is
enabled.
Serial Cmd:
<K102,status>
Default:
Disabled
Options:
0 = Disabled
1 = Enabled
Note: The default setting can only be changed in
readers with multiplexed RS-232 / RS-422 ports. It is forced to
1 (enabled) in
readers with "dedicated" RS-422 ports.
Note: The USB version of the MS-4 does not support
RS-422.
