3.1. Set DIP Switches

The DIP Switches located on the CAS-81 back panel are used to set the Data Rate, Timeout Selection, Quiet Mode, Broadcast Mode, and other features. Note that a label on the underside of the CAS-81 unit also describes DIP Switch settings.

3.1.1.Data Rate (Baud) Selection (Switches 1 through 3)

Select the Baud Rate for the Control Port. The Baud Rate must match that of the control device. The CAS-81 is transparent to parity and will operate at 7 bits even or odd parity, and at 8 bits no parity.
