1.2 CONNECTORS DESCRIPTION
The pinout for all the electrical access is described in the sections hereafter.
1.2.1 General Purpose IN
For forward product compatibility the GP IN section is split on two kind of connectors.
The input 1 and 2 are shared with each Serial signal transmission RJ 45 terminal, labeled "RS GPIO".
These inputs are protected by opto-coupler but are not floating, a grounding on the input pin triggers the GP-
IN.

The input 3 to 8 are on one D-SUB 15 terminal female socket. Inputs are independent and electrically
isolated by opto-couplers. Each input is none polarized and feature an automatic 5mA current limitation
working with an input voltage of 5 to 24 Volts. User do not have to care of your wiring polarity for these ones.
Ground and power pins are available on the connector to ease interfacing with others machines especially if
the information is supplied by a dry contact, open connector, ground closure.
The 12 volts output of the stage racer is protected against external short circuit by a internal 100mA
resettable fuse (polyswitch) common to GPIN and GPOUT socket.
