Connect to an X2 via Wi-Fi


Turn On Wi-Fi

All X2-Series Data Loggers are equipped with on-board Wi-Fi communications. Outside of a scheduled transmission period the Wi-Fi is powered off. The primary method used to enable the Wi-Fi module of an X2 is to Cycle Power.

The methods for removing and re-applying power differ depending on the model of X2 logger:


To cycle power on the standard, pole-mount X2 disconnect the 6-pin cable from the central port. This will remove the external power source supplied by an SP-Series solar power pack, UW6-PW power adapter, or user-wired UW6-FLx cable.  After waiting approximately 30 seconds, reconnect this cable and verify the LEDs visible through the top of the logger begin to blink.

In addition to a power cycle, the Wi-Fi module of a standard X2 can be enabled by inserting a magnet into either of the two recesses in the logger lid. A small flathead screwdriver with a magnetic base is included with each X2 system for this purpose. Note that a green LED beneath the recess will illuminate when the magnet has activated the switch.

Insert magnet into either lid recess to turn-on the X2 Wi-Fi module.

Wi-Fi for X2-Iridium satellite systems is disabled on power-up so a magnet swipe is required to enable it. 




Buoy-mounted X2 loggers recieve power from a battery harness sealed beneath the CB plate in the buoy data well. The buoy solar panel cable acts as a switch to connect the battery circuit. Disconnect the 6-pin solar panel cable from the SOLAR/COM port on the X2-CB, wait approximately 30 seconds, and re-connect it to apply power. A buzzer will sound when power is applied.

Note that Wi-Fi of X2-CB systems with Iridium satellite telemetry is permanently disabled for communication timing reasons and cannot be enabled with a power cycle.



If the system is an X2-SDL, unscrew the white battery lid at the top of the unit to remove it. Wait 60 seconds before rethreading the battery lid onto the top bulkhead of the SDL. A buzzer will sound when power is applied.

  • Ensure that 16 Duracell D-Cell batteries (4 in each tube) are installed and that the batteries in each tube are in the same positive (+) and negative (-) orientation. Orientation labels are adhered to the inside and top of the battery tubes.

Remove the white battery lid by rotating it counterclockwise. The included hex tool can be inserted into one of the two bore holes on the lid to provide extra leverage.

Connect to the X2’s Local Wi-Fi Network

Following a power cycle, the X2’s local Wi-Fi network will remain active for 10 minutes. If the network is not visible or the connection to it expires, cycle power an additional time to reset the Wi-Fi and re-connect.

  1. Using a laptop or smartphone, search for the logger SSID.
    1. The network name will reflect the X2’s logger Body Tag number.
    2. Locate the X2-logger network. The SSID will match the system body tag from the factory.


      2. Connect to the X2’s Network.
