Laser LS8000-3 manual Baud Rate Indication on Power Up, Number of Comm Baud Rate LED Blinks

LaserSpeed 8000-3 Instruction Handbook

RS-232/RS-422 Communication

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.
