2.3.2 General Purpose OUT
For forward product compatibility the GP OUT section is split on two kind of connectors.
Outputs 1 and 2
are shared with each Serial signal transmission RJ 45 terminal, labeled " Serial/Gpio ".
These outputs are on floating dry contact relays with 50 Volts AC/DC and 0.25A switching capacity.
The relay is open if the corresponding remote input is not triggered.

Outputs 3 to 8
are on one D-SUB 15 terminal female socket. These outputs are also on floating dry contact
relays with 50 Volts AC/DC and 0.25A switching capacity. The relay is also open if the corresponding
remote input is not triggered.
Ground and power pins are available on the connector to ease interfacing with others machines especially if
the driven machine need a voltage information rather than a contact closure.
The 12 volts output of the Stage Racer 2 is protected against external short circuit by an internal 100mA
resettable fuse (polyswitch) common to GPI and GPO sockets.

Each GPI can be affected to one or Multiple GPO by using the GPIO routing grid of the Stage racer 2.
