LaserSpeed 8000-3 Instruction Handbook

Interfacing with the LS8000-3

DB25 Connector

The 25-pin interface port contains pins which deliver the quadrature pulse outputs, RS-232 serial communications, safety interlock signals, and the 24 V supply required to power the gauge. Several inputs are available for operation of the instrument. The connector is a standard 25-Pin male D-Sub connector. The connector is shown below looking at the gauge's rear panel with the gauge base plate down.
