Replace a RF-Cable Assembly

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

 

Tools Required:

-Phillips Head Screwdriver

-3/16″ Hex Driver or Adjustable Wrench

-5/8″ Socket

Instructions

    1. Locate the green plastic wire from its track in the base of the X2’s aluminum housing.

 

    1. Slide tweezers or the tip of the screwdriver packaged with the X2 beneath the wire to expose it.

 

    1. Pull the end of the wire while applying pressure to the top of the X2 to remove it from the track. Tweezers or needle-nose pliers can be used if needed. 

 

    1. Pull up on the enclosure to separate it from the X2 base.

 

    1. Press down on the tabs of the upward-facing UW6 Direct and downward-facing UW6 RTU JST connectors and gently pull to remove them from the Main PCB.

 

    1. Remove the (4) visible Phillips-head screws and lock washers from the top of the Main PCB

 

    1. Gently lift up on the Main Board to disconnect the board-to-board connector and expose the RTU PCB.

 

    1. Use a 3/16″ nut driver or adjustable wrench to remove the four standoffs on the bottom PCB.

 

    1. Tip the RTU PCB to reveal the gold MMCX RF connector.

 

    1. Pull upwards on the MMCX connector to remove it from the P2 port on the RTU PCB.

 

    1. Use a 5/8″ socket to loosen the cable assembly port by hand.

 

    1. Remove the old assembly from the X2 housing.

 

    1. Evenly spread O-ring grease onto the replacement cable assembly’s O-ring.

 

    1. Use the 5/8″ socket to tighten the new RF cable into the port. Ensure the other end of the cable is free to turn with the port.

 

    1. Once fully hand-tightened, the cable O-ring should not be visible.

 

    1. Align the MMCX connector of the new cable with the P2 port on the RTU board. Press downward firmly until a click is felt signifying a secure connection.

 

    1. Pivot the RF cable such that it runs along the full length of the modem.

 

    1. Place the RTU PCB back on top of the base and hand tighten the four standoffs back in place. Follow up with an additional 1/8 of a turn using the nut driver or adjustable wrench.

 

    1. Align the board-to-board connector and place the main board back on top of the RTU board, pressing down gently until the connector locks into place.

 

    1. Tighten the top PCB back in place using the four Phillips screws and lock washers.

 

    1. Re-connect the UW6 RTU JST connector, gently pressing in until a click is heard.

 

    1. Re-connect the UW6 Direct JST connector.

 

    1. Slide the enclosure back over top the X2 base, ensuring that no wires are pinched.

 

    1. Align the wire entry with the machined body tag on the aluminum base.

 

    1. Push down on the top of the enclosure and feed the wire back into its track.
