NCR 280 Installation
1. Ensure that the NCR 280 is powered down and unplugged. Open the door
on the top, left-hand side and remove the two screws which fasten the steel
plate to the terminal cover. Slide the steel plate to the left to remove.
2. Remove the two round head screws from the back of the terminal. Be sure
the doors on the left and right side of the terminal are open and that there
are no keys inserted in the locks on the front. Lift off the terminal cover.
3. Locate the card edge connector to the left of the keyboard. Mark the top
side of the connector before removing it from the keyboard.
4. Remove the four “C” clips that hold the keyboard in place. Remove the
keyboard.
5. Feed the end of the RL 470 base station cable with the 2x8 header connector
under the large capacitor mounted horizontally in the terminal power
supply. Next feed the cable between the two large vertically-mounted
capacitors then through the hole in the plate adjacent to these two
capacitors. Feed through enough cable so that the cable reaches the
terminal keyboard.
6. Mate the 2x8 header connector to the connector on the interface board.
Note that pin 10 is keyed.
7. With the component side up on the interface board, connect the card edge
connector on the interface board to the card edge on the keyboard. The
interface board will be mounted under the keyboard PC board.
8. Connect the card edge connector, removed earlier from the keyboard, to the
interface board, with the marked side facing down.
9. Replace the keyboard with the interface board attached. Be sure the
interface board is installed so that it doesn't interfere with any cable
assemblies. Replace the “C” clips.
10. Remove any slack in the RL 470 base station cable by gently pulling it back
through the terminal power supply.
11. Using the cable tie provided, secure the base station cable to the cable
bundle near the capacitor, which is mounted horizontally approximately 6
1/2 in. from the rear of the terminal.
