Tools Required

9/16″ Socket Wrench

Phillips-head Screw Driver

Tweezers (recommended, not required)

X2-CB

 

1. Disconnect the 6-pin solar panel or UW-6 USB cable from the X2-CB SOLAR/COM port to remove power from the data logger.

2. [For CB-150, 450 buoys only] Remove the buoy’s solar tower to gain access to the data well.

  1. Remove the (6) 3/8-16×3/4 bolts and 3/8 lock washers holding the solar tower to the buoy using a 9/16 socket wrench

Remove CB-150/450 Solar Tower

 

3. Remove the (8) 3/8-16×3/4 bolts and 3/8 lock washers from the X2-CB using a 9/16 socket wrench, loosening them in a cross pattern.

4. Remove the (8) 8-32 x 1/2 O-ring screws holding the X2 enclosure to the metal plate. 

Caution!!!- Be sure to statically ground yourself prior to touching any of the electronics inside the X2 logger

5. Invert the logger plate to expose the RTU PCB of the X2.

6.  Using even pressure (two hands highly recommended), lift up on the modem. to remove it from the RTU board socket.

7.  Gently pull up on the connector of the white UFL cable on the old modem to disconnect it. Take care to not pull on the wire, but the metal head end itself. The use of tweezers can help pop the connector out.

8. Locate the new modem and note the number of pins for the correct orientation. Both the RTU board and modem have mating connectors for a 24-pin and 25-pin side, respectively.

9. Move the UFL cable out of the way and make sure it is clear of the socket prior to aligning the pins for installation.

10. Align the pins and apply even pressure to both sides of the modem to push it into place.

11. Attach the free end of the UFL cable to the ‘cell’ socket on the new modem. Push down on the connector until a click is heard.

12. Place the X2-CB plate back on top of its base.

a. Ensure the eight small O-rings and the large exterior O-ring are secure in their grooves and are making proper contact with the bottom of the logger plate.

b. Orient the X2-CB plate such that the power cable feeding up through the bottom of the base lies flat when closed.

13. Align the blank plate threads with the top plate and hand-thread the (8) 8-32 x 1/2 O-ring screws halfway, before tightening in a cross pattern with a Phillips Screwdriver.

14. Place the re-assembled X2-CB back on top of the data well.

a. Make sure the primary O-ring is clear of debris and centered in the groove.

b. Align the plate and re-install the (8) 3/8-16×3/4 bolts and 3/8 lock washers, tightening them in a cross-pattern using a 9/16 socket wrench.
