7-5
Pin 6: NO contact 4
Pin 7: +5 VDC
Pin 8: Ground
Pin 9: +5 VDC
Notes
The relay 1 and 2 contacts are electrically separate, but operate in unison. The relay 3 and 4
contacts are electrically separate, but operate in unison. The +5 VDC pins are connected
internally through 1K resistors to +5 VDC and can source 5 mA. This voltage can be used with
the relay contacts to create an active high output for some devices that require a +5 VDC signal to
activate. For example, connecting pin 7 to pin 3 of the Relay 1&2 connector will result in +5
VDC on pin 2 when the relay is activated.
Opto 1-4 In (Opto-isolated control inputs)
Type: 9-pin male D-Sub
Pin-out: Pin 1: Input 1 Gnd
Pin 2: Input 2 Gnd
Pin 3: Input 3 Gnd
Pin 4: Input 4 Gnd
Pin 5: Gnd
Pin 6: Switch contact input 1
Pin 7: Switch contact input 2
Pin 8: Switch contact input 3
Pin 9: Switch contact input 4
Note
A contact closure between any switch input and ground will activate that input. The switch
contact inputs are also connected internally through 1K resistors to internal +5 VDC and can
source 5 mA for use with an external transistor switch circuit.
OC 1 & 2 Out (J2)
Type: 9-pin male D-Sub
Pin-out: Pin 1: Gnd OC1
Pin 2: Emitter OC1
Pin 3: Collector OC1
Pin 4: Gnd OC2
Pin 5: Emitter OC2
Pin 6: Collector OC2
Pin 7: 5 VDC
Pin 8: No connection
Pin 9: 5 VDC
Headset (External headset connector)
Type: 9-pin male D-Sub
