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
LaserSpeed 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, Data Bits, Parity, not
Baud Rate, Data Bits, Stop Bits, Parity.
