Hardware Replacement
To remove and replace a thruster, follow these steps:
1. Power down the system.
2. Remove the top float block by removing the four screws holding the float block to the frame.
3. Note the position of the thruster being replaced in the vehicle frame. The position of the thruster
being replaced will determine the propeller orientation and configuration parameters to be
programmed into the replacement.
4. For the thruster to be replaced, follow the thruster cable to the main thruster connector stack
(located under the main float block) and disconnect the damaged thruster from the stack.
5. Carefully thread the disconnected cable and connector back through the frame until it is clear.
6. Using the 5mm hex driver, remove the two (2) M6 plastic thruster bolts securing the thruster to
the frame.
7. Remove the damaged thruster from the vehicle. If the propeller is still in good shape, remove it
from the damaged thruster using a 7/16" nut driver.
8. Install a new correct orientation propeller (or the recovered propeller) on the replacement
thruster.
9. Note the serial number for the replacement thruster. This number will be used to identify and
program the replacement thruster once installed in the vehicle.
10. Install the replacement thruster in the same location as the one being replaced, and thread the
cable and connector through the same routing as the old thruster. Connect the cable to the
same location in the connector stack as before.
11. Mount the thruster to the frame using the M6 nylon bolts, and the 5mm hex driver. Do not
overtighten the bolts.
12. Replace the float block using the screws removed earlier.
Thruster and Control Software Configuration
Refer to the configuration parameter table in the Thruster section of the Equipment Guide.:
Commands below are case sensitive.
1. Connect and power up the system, but do not start the control software.
2. Launch the terminal program and use the following commands to program the thruster.
3. Navigate to the working folder, type:
cd flighthack followed by the Enter key
4. Enumerate the modules on the system, type:
vr_enum followed by the Enter key
5. The replacement thruster serial number should appear in the list of enumerated devices. Note
that the serial number on the thruster strut is only the ending significant digits. The serial
number found in the output from vr_enum uses the complete format, such as THRxxxxxx, where
xxxxxx is the sequential number.
6. Register the replacement thruster, type:
vr_setid SN NodeID GroupID followed by the Enter key
