All DS1500 models are equipped with a cable terminated by a 15-pin male D-sub
high-density connector for connection to the power supply and input/output signals.
The details of the connector pins are indicated in the following table.
CAUTION
Do not connect GND and SGND to different (external) ground
references. GND and SGND are internally connected through
filtering circuitry which can be permanently damaged if subjected to
voltage drops over 0.8 Vdc.
