GPI Connector Pinout

GPI Connections

GPI DE-9 Connector Pinout

The GPI inputs and outputs are electrically isolated from the power and ground on

the FS1 frame. There are two inputs and two outputs. Electrical isolation is

provided for up to two pieces of external equipment. The following guidelines apply

to the two GPI inputs and outputs:

• Input 1 and Output 1 share a common isolated ground on pins 6 & 8 (I/O

Ground 1),

• Input 2 and Output 2 share a common isolated ground on pins 7 & 9 (I/O

Ground 2).

• Pin 5, local chassis ground, may only be used as a reference when isolation is

not required.

• Both GPI inputs are internally pulled high through a 10K ohm resistor to an

isolated 5V supply, so that a relay contact closure or any device sinking at least

0.4 mA to ground will register a logic low.

Both GPI outputs are 5V TTL compatible, sourcing up to 6mA and sinking up to

4mA each.
