LaserSpeed 8000-3 Instruction Handbook
RS-232/RS-422 Communication
Part No. 93463 / Drawing No. 0921-01561 Page 123 of 221 Revision A (Sep 2007)
recommends that the RS-422 port be used for high speed, long distance
communications.
Note: High-baud rates are only required when acquiring length and speed
data over the serial port. If you are using the pulse outputs, and are
only using the serial port for configuration and/or diagnostics, you do
not need a high baud rate. The maximum baud rate that will work for
a particular application is dependent on the length of the cable and
the amount of electrical noise in the environment. If you are using a
high baud rate and are having problems communicating, try using
LaserTrak to switch to a slower rate.
Baud Rate Indication on Power Up
The LS8000-3 indicates the selected baud rate setting for both the RS-232
and RS-422 ports at power-on, whenever a baud rate setting is changed, and
when the auto-baud feature causes a baud rate change on one of the ports.
The COMM LED flashes a number of times, indicating the selected baud rate.
While the COMM LED is blinking, the Valid LED indicates the selected framing
(OFF for 7N2 and ON for 8N1.)

The COMM LED indicates the baud rate for each port 4 times. Each series of
blinks is separated by a pause of a few seconds. The RS-232 baud rate is
indicated by blinking Orange, and the RS-422 baud rate is indicated by
blinking Blue.
