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.

– Voltage input for Isolated Pulse Outputs (5 to 28V DC). The voltage
supplied will be the voltage level of the pulse outputs supplied by the LS8000-3.
If a Voltage is not supplied, the pulse outputs will be approximately 4.5V.
