2.3 ELECTRICAL CONNECTIONS
Several DS2100 models are equipped with a cable terminated by a 25-pin female D-
sub 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.
