The recommended settings will enable binary communication mode between the
gauge and the I/O module and allow for the fastest possible data throughput. If
you are using a different baud rate/framing configuration, you can change the
LaserSpe
ed gauge’s baud rate/framing to the recommended settings by sending
the command
@11<CR>
to the gauge. To set the I/O module to the same baud
rate/framing, sending the following command to the I/O Module:
~B230400,1,8,None<CR>
.
Note:
When synchronizing multiple gauges, the SyncMode setting should be set
to 1, and all gauges’ $H settings set to 9. This will allow the I/O Module to rely on
the gauge’s synchronization output timing for increased performance. This is
required when operating synchronized gauges with fast update rates.
Note:
The gauge’s RS422 baud rate should be changed before changing this
setting (using the
@
command), as changing the I/O Module’s baud rate will make
the I/O Module unable to communicate with the gauge if the two devices’ baud
rates no longer match.
Note:
Communication between the I/O Module and the gauge can be check by
viewing the lights on the I/O Module’s front panel. If the lights are functioning
properly the gauge and the I/O module are communicating properly.
Note:
The order for the baud rate/framing for the I/O module is:
Baud Rate,
Stop
Bits,

Bits, Parity, not
