Connector: Berg 50-way IDC.
Seen: Looking into PCB-mounted header.

GND: Ground reference voltage

+5V: Powers most logic.

+12V: -12V: Primarily useful for RS232 buffer power.
When designing signal conditioner boards using these rails,
take care to avoid noise from here affecting sensitive
analogue circuitry.

DAC: D to A outputs

Ch: Channels (input or output)
