3 SIM Card Installation

3.1 Enclosure Opening

Unscrew 4x socket head cap screws using a size 5 Allen key. Lift the enclosure lid carefully.

3.2 SIM Socket Operation

Slide the SIM socket cover toward the right and slip it up. Insert the micro SIM card onto the socket. Slip the socket cover down and slide it toward the left.

3.3 Closing the Enclosure

Close the top enclosure. Ensure the enclosure orientation 'KEY' is matched.

3.4 Securing the Enclosure

Fasten the 4x socket head cap screws with a size 5 Allen key. Follow the specified steps and torques to ensure the enclosure is sealed properly:

• Fasten screws at locations 1, 2, 3, and 4 with a torque of 10 kgf.cm.

4 Connecting MK6 RSU

4.1 Ethernet Connector Assembly

Assemble the Ethernet connector using an M12 X-Coded field-attachable Ethernet connector. The MK6 RSU can only be powered through the Ethernet port, supporting either Mode A (Endspan) or Mode B (Midspan). The Field-Attachable Ethernet connector suits 7.7-9.0mm diameter cable by default. Use the correct alternative grommet supplied for smaller (5.5-6.7mm or 6-7.7mm) diameter cable. Please refer to the instruction sheet that comes with the M12 connector when assembling it.

4.2 Antenna and Ethernet Connection

Connect the DSRC, C-V2X, LTE, Bluetooth/WLAN, and GNSS antennas, along with the M12 Ethernet connector, to the appropriate ports on the MK6 RSU unit.

4.3 Water Intrusion Prevention

Wrap the N-connector and antenna joints with the provided Self-Fusing Rubber Tape to prevent water intrusion:

• Cut a small length (10cm) of Self-Fusing tape.
• Remove the backing film.
• Begin wrapping Self-Fusing tape around the N-connector and antenna joint. Stretch tape to 300% and wrap it spirally around the object with a 50% overlap.
• Repeat steps and ensure at least one complete wrap is applied.
• Cut off any excess.

Process steps: Ensure the surface is clean, Stretch tape and wrap, Done.

4.4 Mounting Options

Both vertical and horizontal mounting using the bracket are supported.

4.5 Pole or Wall Mounting

The bracket can be mounted to a pole using the provided Stainless Steel straps, or bolted to a wall through four mounting holes in the bracket. The ground wire is recommended to be connected to a good common earth point.
