Using a Custom Serial Cable Design
!
When creating a custom serial cable connection (refer to "Establishing the
Data Connection"), you can provide power to the controller through the
mating Molex connector:
1.
Obtain a 7-pin Molex connector 51004-0700.
2.
Attach power and ground to the connector, (Pin 6: +5V, Pin 7: Ground).
Using an External Wall-Mount Power Supply
If you are using a standard MicroTouch RS-232 serial cable (P/N 7310101),
you can use either a 120 volt wall-mount power supply (P/N 19-408) or a
220 volt wall-mount power supply (P/N 19-409).
!
To connect an external wall-mount power supply:
1.
Remove the plastic plug covering the power jack of the 9-pin D
connector on the serial cable.
2. Connect a DC power plug to the power jack built into the 9-pin D
connector.
3. Plug the power supply into a grounded outlet. The power plug supplies
both +5V and ground.
Using a Keyboard Power Tap Cable
If you are using a standard MicroTouch RS-232 serial cable, you can use
either a 5-pin IBM AT compatible keyboard power tap cable (MicroTouch
P/N 19-356) or a 6-pin IBM PS/2 compatible keyboard power tap cable
(P/N 19-357).
!

2.
Plug the keyboard cable into the power tap cable.
