Digital Output Signals
The PreciseFlex robot provides 4 general-purpose optically isolated digital output signals at the G1400B
controller.
These output signals can be configured as "sinking" or "sourcing". As shipped from the factory, the
output signals are configured as "sinking", i.e. the external equipment must provide a 5VDC to
24VDC pull up voltage on an output pin and the controller pulls this pin to ground when the signal is
asserted as true.
Alternately, the output signals can be configured as "sourcing", i.e. the external equipment must pull down
an output pin to ground and the controller pulls this pin to 24VDC when the signal is asserted as true.
Outputs can be individually configured as sinking or sourcing signals. For more information on
configuring the jumpers, please see the Guidance Controller, Hardware Introduction and Reference
Manual.
The pin out for the G1400B Digital Input and Output Connector and the corresponding GPL signal
numbers are described in the following table.
