Configuring PAX Terminal Ethernet Connections

You can connect the PAX A35 payment terminal to your local area network (LAN) using a wired, Ethernet connection. These are some of the benefits of using an Ethernet connection instead of a Wi-Fi network connection:
  • Security: Ethernet connections are usually more secure than Wi-Fi connections because access to the network is limited to devices that are physically connected to the router or network switch.
  • Stability: Ethernet connections are typically more stable than Wi-Fi connections because there is no interference caused by wireless signals from nearby wireless devices.
  • Speed: Ethernet connections generally have less
    latency
    than Wi-Fi connections, which is the time it takes for data to travel from one point to another.

Connecting the Ethernet Cable to the PAX Terminal

In order to use an Ethernet connection, you must have an Ethernet cable. This type of cable is not provided with the PAX device.
Follow these steps to connect the Ethernet cable to the PAX terminal:
IMPORTANT
You cannot connect the PAX A35 terminal to a POS system using a standard USB or RS-232 serial port.
  1. Attach one plug on the Ethernet cable to the red port on the multifunctional cable.

    ADDITIONAL INFORMATION

    For more information about the multifunctional cable, see Connecting the Multifunctional Connector Cable to the PAX Terminal.
  2. Connect the other plug on the Ethernet cable to the compatible port on your point-of-sale (POS) system.
