Connect the Terminal

Before anything else, connect the S80 via phone line or ethernet (LAN) cable and plug it into power. This terminal needs a network connection to be able to communicate with the processor and run transactions.

*Ethernet cable must be purchased separately.

  1. On the back of the S80, plug an ethernet cable into the 'LAN' port OR the phone cable into the 'LINE' port.

    An ethernet connection is recommended for faster transaction speeds.

  2. Plug the other end of the ethernet cable into an open numbered port on the router.

    If using the telephone line, connect the other end of that cable to an analog wall jack not shared with other devices.

  3. Plug the power cable into the 'POWER' port.
