NCR 7169 Multifunction Printer 1-9
Connecting the Cables
There are three different types of cables that connect to the printer:
• Power supply cable supplying power from the host POS terminal or from an
external power supply
• Communication cable (RS-232, USB, or LAN) connecting the printer to the host
computer
• Cash drawer cable connecting the printer to one or two cash drawers
Warning: Do not use a cash drawer with an impedance of less than 24 ohms.
Caution: Disconnect the power before connecting the cables. Always connect the
communication cable and cash drawer cables before connecting power to the power
supply. Always disconnect power to the power supply before disconnecting the
communication and cash drawer cables.
To connect the cables, follow these steps:
Note: Refer to the images in the next sections for more information.
1. Disconnect the power supply from its power source.
2. Connect the communication cable to the printer and to the host computer connector.
Warning: To avoid shorting cash drawer connector pins, be careful not to insert
the USB connector into the cash drawer port. Do not connect the USB cable to
the Cash Drawer connector.
3. Connect the cash drawer cable to the printer and to the cash drawer.
Note: The connector is a standard phone jack located at the rear of the printer.
4. Connect the power cable to the printer.
5. Route the cables through the cable strain relief feature on the bottom of the printer
and through the two slots in the cable access cover.
6. Reconnect the power cable to a power source.
• For remote power supply installation, connect the power cable to the power
supply and connect the power supply to an AC outlet.
• For host powered installation, connect the power cable to the POS terminal.
Note: At this point, the printer receives power from its power source. If the Online LED

to ensure that the host terminal or the power supply is on.
