Gemini GT6 Hardware Installation Guide
Digital Inputs (optional)
The Gemini drive has eight digital inputs. All connections are shown in the next
drawing. Defaults are shown in parentheses, but you can use the INFNC command
to redefine the function of any of the inputs. See the Gemini Programmer's
Reference for more information.
By default, these are +24VDC sourcing inputs. You can use VINref (pin 26) to
change the switching voltage level. You can also use CNTRL-P (pins 27 and 33)
to change the inputs from sourcing to sinking inputs.

Inputs
You can use the INLVL and INDEB commands to configure the inputs as active
high or active low, and to set the debounce time, respectively.
CNTRL-P – Reference for Digital Inputs (optional)
Use CNTRL-P (pins 27 and 33) to change the digital inputs from sourcing inputs
to sinking inputs.
It is not necessary for you to make any connections to CNTRL-P. If you connect
nothing, then the inputs are internally pulled up to VINref. If sourcing inputs are
appropriate for your application, then make no connections to CNTRL-P.
If you connect CNTRL-P to digital ground, then the inputs will become sinking
inputs, and will sink current.
Inputs internally pulled up to
+24V, unless you connect an
external 5 – 24VDC supply to
the VINref terminal.
