NCR 2154/2155 Installation
1. Power-down the NCR 2154/2155 POS terminal.
2. Remove the keyboard by grasping the keyboard cover at its corners and
lifting upward.
3. Remove the cable connecting the keyboard to the terminal’s main PC
board.
4. Install the LL 500 cable in place of the keyboard cable just removed. The
modular connector should be connected to J1 on the keyboard, and the 6-
pin square connector should be connected to J4 on the terminal’s main PC
board.
5. Reinstall the keyboard by first placing the tabs, located on the back left and
back right of the keyboard cover, behind the tabs located in a similar
position on the terminal. The keyboard cable should be made to pass
through the notch located at the rear left side of the keyboard cover.
6. Finally, making sure that the remaining tabs on the keyboard cover are
positioned inside the terminal housing, press down on the keyboard cover
until it snaps into place.
You can now attach your scanner and peripheral devices.
