# RFM2-Dual LiDAR Mobile Accessory ## Download Setup and Operations Checklist [#download-setup-and-operations-checklist](#download-setup-and-operations-checklist "mention")[https://phoenixlidar.com/wp-content/uploads/2024/07/Ranger-Flex-RFM2-Drive-Checklist-v1-8\_24.pd](https://phoenixlidar.com/wp-content/uploads/2024/07/Ranger-Flex-RFM2-Drive-Checklist-v1-8_24.pdf) *** ## Prepare and mount the RANGER-UAV22 FLEX {% hint style="info" %} The R6 camera and all cables must be removed from the RANGER-UAV22 FLEX before installation onto the RFM2 base plate. {% endhint %} {% hint style="warning" %} Only mount the RANGER-UAV22 FLEX Scanner to the zero-point mount when the RFM2 is detached from the roof rack and placed on a sturdy, flat surface. {% endhint %} Check that the zero-point mount is set to the open position and is clear of any obstructions before lowering the RANGER-UAV22 FLEX into the RFM2 base plate.

Ensure cables are clear and the gold-colored mounting base is in the open position.

Make sure there is no gap between the zero-point base and the bottom of the RANGER-UAV22 FLEX before tightening the zero-point mount using the supplied torque wrench and 6mm hex driver. Ensure the torque wrench is set to tighten in the clockwise direction and torque to 25 ft-lbs until a “click” is heard and felt. {% hint style="warning" %} Attempting to tightening the zero-point mount when they system is not fully seated can damage the mounting system or fail to secure the scanner. If there is a gap but no obstruction between the scanner and zero-point mount, check that the zero-point mount is in the fully open position. {% endhint %}

Torque to 25 ft-lbs in the clockwise direction until “click” is heard and felt in the torque wrench.

Connect the RFM2 cables to the RANGER-UAV22 FLEX, plugging the DC IN, Ethernet, Sensor, IMU (optional), and Camera LEMO connectors and hand tightening the GPS 1, GPS 2 (do not swap!), and Wifi connectors. Cables should be routed to avoid straining. Verify that the fixed scanner is connected to the RANGER-UAV22 FLEX with the SENSOR cable.
Insert the SD Card (formatted with exFAT) into FLEX Pack, ensuring that write protection is switched off.
Inspect the system for overstrained cables, debris, loose or frayed wires, damaged connectors, etc. Clean the lenses on scanners and Ladybug. Install the RFM2 cover over the sensors and secure the latches.
Inspect Roof Rack Mount for loose or missing hardware. Also check for dirt and debris that might interfere with the installation of the RFM2 or the Ladybug camera mast. {% hint style="warning" %} Before installing or transporting the RFM2, make sure the handle is fully locked in position by the two plunger pins. {% endhint %} Install the RFM2 onto the roof rack by sliding it into the hinge mechanism. {% embed url="" %} Video installation of RFM2 head unit onto roof rack plate. {% endembed %}
Fully tighten the 2 knobs (hand-tight) on the hinge point (towards vehicle front).
To set the scanning angle, unlock the plunger pins that secure the handle before tilting the RFM2 platform upwards to align the handle pins into the slots of the side rails. Lower the scanner and fully tighten (hand-tight) the two knobs towards the vehicle rear to lock the handle in place.
## Install the Wheel Sensor onto the Vehicle Wipe the car body clean where the suction cups are to be attached using a microfiber cloth before mounting the suction cups on the car body. Refer to the Wheel Sensor User Manual for how to mount the wheel sensor and connect, route, and secure the wheel sensor wires. Secure the wheel sensor leash, taking up excess slack in the line. {% embed url="" %}
*** ## Install the LadyBug Mast or Primary GNSS Antenna Kit **Ladybug Mast** Check that zero-point mount for the LadyBug mast is in the open position (golden blocks just past flush). Position the mast over the mounting studs on the roof rack. Make sure there is no gap between the zero-point mount on the mast and the roof rack base plate before tightening the mount.
{% hint style="info" %} The zero-point mount should only be operated from the passenger side of the vehicle (connector side of the mast). {% endhint %} Using the supplied torque wrench and 6mm hex driver, ensure the torque wrench is set to tighten in the clockwise direction and torque to 25 ft-lbs until a “click” is heard and felt.

Tighten to 25 ft-lbs using the pre-set torque wrench.

**Primary GNSS Antenna Kit** (if available - LadyBug Mast not used) When the LadyBug is not being used, mount the Primary GNSS Antenna Kit on the roof rack base plate in the threaded hole on the roof rack between the zero-point studs.
The Primary GNSS Antenna Kit is connected using a single cable to the ANT1 connector on the RFM2
*** ## Install Cables Connect all exterior cables to their respective plugs and receptacles using the labels on the cables as reference. The wheel sensor port is accessible by opening the small door on the side of the RFM2 cover. The door can be closed again once the cable plug is connected. Secure the umbilical cord along the side of the roof rack frame using the attached clamps. Install the Wifi antenna if the ethernet connection cannot be used.
*** ## Interior Hardware Setup Check battery voltage for the RFM2 and install the battery alarm. Mount the Mission Guidance Monitor to the windshield using the suction cup mount. Connect the monitor to the USB hub using the HDMI to USB-C cable.
From the umbilical, connect the Ethernet cable from the RFM2 and USB-A cable from the LadyBug to the supplied USB hub. The USB hub is powered via the included power supply which plugs into the 12V accessory port in the vehicle using the included inverter. Connect the USB hub to the laptop using the USB-C output. Remove all LiDAR protective caps. Connect the 6S Lipo battery to the XT-90 connector on the umbilical cable. The system is now ready to power on and connect to SE8. *** ## Disassemble Hardware **Disconnect Cables** {% hint style="danger" %} Make sure the system is **fully powered down** (CPU Button LED off, all LEDs on the RANGER-UAV22 FLEX off (visible by opening the small door on the side of the cover) prior to disconnecting power to the system. {% endhint %} {% hint style="danger" %} All power sources to the system **MUST** be disconnected before any other external cables are unplugged. {% endhint %} Make sure the system is fully powered down (CPU Button LED off, all LEDs on the RANGER-UAV FLEX off (visible by opening the small door on the side of the cover). When it has been verified the system is fully powered down, disconnect all power sources to the entire system. Then, unplug all external cables from the dual head accessory and the LadyBug mast (DC IN, Ethernet, Camera, USB, GPS). \ **Removing the RANGER-UAV FLEX from the RFM2** {% hint style="warning" %} The RFM2 must be on sturdy, flat surface to remove the RANGER-UAV FLEX from the quick release mount. Do not attempt to release the LiDAR while the RFM2 is on the roof rack. {% endhint %}
Set the direction of the torque wrench to the “release” direction (counter-clockwise). Release the zero-point mount using the torque wrench in counter-clockwise direction until the screw freely turns. Hand loosen until the golden blocks on the zero-point mount are just past flush or a resistance is noticed. Do not release the mount any further after the resistance is felt. Holding the RANGER-UAV22 FLEX by the sides, gently wiggle and lift up to release the scanner from the RFM2. Store the RANGER-UAV22 FLEX securely in its case when not in use.
