NCR 2152 Installation
1. Switch off the NCR 2152. Remove the two large, pan head screws from the
front of the terminal to allow the top section to open up. Use the two hood
support rods located to the sides of the housing to support the top section.
2. Locate the large steel plate covering the printed circuit board assembly.
Remove the two screws on the right-hand side of the plate. Loosen, but do
not remove, the two screws holding down the left side of the plate. Slide
the plate to the left, lift up and remove to expose the component side of the
processor board.
3. Locate the Keyboard Interface connector at the back left of the processor
board. This connector will be designated either J12 or J8, depending on the
processor board used. Mark the top of the connector with tape or a felt
marker.
4. Feed the base station cable up through the opening at the back of the
terminal. The opening is on the same side as the Keyboard Interface
connector.
5. Connect J1 of the base station cable to the mating connector, P1, on the cable
T-Connector provided (P1 is the middle connector).
Note: Position 16 for the connector pair is keyed.
6. Unplug the Keyboard Interface connector. Connect the Keyboard Interface
ribbon cable (marked side up) to P2 of the T-Connector. P2 is the top
connector on the T-Connector; position 2 of the connector pair is keyed.
7. Connect J1 of the T-Connector to J12/J8 on the terminal processor board.
The T-Connector can mate with J12/J8 in one direction only.
8. Locate and remove the pan head cable mounting screw on a flat steel panel
in the terminal housing. It is about 4 in. to one side of the T-Connector. Use
the tie provided to secure the cable to the terminal housing; replace the pan
head screw. The cable must be secured so that the T-Connector is seated
vertically (i.e., at 90°) to the processor board.
9. Replace the metal plate that covers the processor board.
10. Remove the hood supports and lower the top of the terminal into position.
Replace the two pan head screws to secure the top housing.
You can now attach your scanner and peripheral devices.
