Power Connector
The power connector
(Amp CPC series) that mates with a supplied 9-pin socket connector
(P/N 98-200002-01). The pin assignments are listed in table 1-5.
Note: Trigger and host connectors can also supply power.
Pins 1, 3, 6, 7, 8, and 9 are identical to those of the trigger connector.
Pins 2 and 4 provide access to the scanner for the auxiliary RS-232 port
and are similar to pins 18 and 19 of the host 28-pin connector.
Pin 5 is internally connected to pin 1 of the host connector and to the exter-
nal case to provide a path for electrostatic discharge or AC faults to pass
directly to ground. It is intended to be connected to a "safety ground" (also
known as "green-wire" or "third wire" ground). It is particularly useful in
installations where the case is not grounded through its mounting plate or
when this connection must be guaranteed even when the unit is
unmounted. This connection allows hazardous currents, such as electro-
static discharge or AC faults, to pass safely to ground instead of traveling
through the unit's circuits or signal cabling.

cable shield, is not effective for this purpose.
