Status lights

The network interface has three lights (NETWORK, DATA, and USB), which indicates the current operating status of the network interface when you first turn on the device, during normal operation, and when errors occur. The NETWORK and USB lights have three colors (red, green, and yellow). The DATA light is green.

The status lights indicate the network interface status, as follows:

NETWORK	DATA	USB	Network interface status
Off	Off	Green flashing	Initializing
Off	Off	Red flashing	Error status
Off	Off	Red and green lights flashing alternately	Firmware update mode
Off	Off	Red on	Printer communication is disabled.
Off	Off	Green flashing when receiving data	Printer communication is enabled.
Red NETWORK light and green USB light flashing simultaneously			Wireless LAN and the IP address are not set.
Red on	Off	Off	Network communication is disabled.
Yellow on	Flashing when receiving data	Off	High speed link
Green on	Flashing when receiving data	Off	Low speed link

Status sheet button

The first time you use the network interface after installing or reinstalling it, plug the power cord of the network interface into a wall outlet while holding down the status sheet button for about twenty seconds to initialize the network interface. The length of time necessary to hold down the status sheet button varies depending on the device model.

Before you start configuring the network interface, be sure to press and hold down the status sheet button on the network interface to print a status sheet. A status sheet provides important information about the network interface, such as MAC address, SSID, device settings, and device's current status. Press the status sheet button once to print a simple status sheet, or twice to print a full status sheet. You cannot print a status sheet when the device has already started printing, or when it is offline or not ready to print.

Note:

If the device does not print a status sheet, make sure the device is online and no print jobs are being processed, then wait a minute. If it still does not print a status sheet, turn the device off, wait until the DATA light goes out while the red USB light is on, and then turn it back on again. The status sheet can be printed one minute after the device finishes warming up.

Caution:

After turning off the device, wait until the DATA light goes out before turning it back on; otherwise the network interface may not work correctly.

USB upstream connector

This connector is used to connect a USB cable to a computer, so that the default network interface settings can be modified by using the configuration utility.

USB downstream connector

This connector is used to connect a USB cable to the device to enable communication with the device.

DC-IN connector

This is an external power supply connector for the AC adapter shipped with the network interface. Plug or unplug the power cord of the network interface from a wall outlet to turn the network interface on or off.

Security lock

You can pass a commercially available theft-prevention cable through the security lock hole to secure the network interface to a table or pillar. This network interface is compatible with the Microsaver Security System manufactured by Kensington.

Rotary stand

The rotary stand is located at the bottom of the network interface. Rotate the rotary stand counterclockwise by 90 degrees to provide an auxiliary stand for stability. The stand can be screwed to a location or on the wall for hanging.
