Cab Bus voltage drop calculator

If your cab bus and / or cabs are not working correctly or your cabs have display issues you might have a low voltage dues to loss from cable length. The minimum operating voltage for the Cab Bus is 8v DC as measured on the UTP Panel and cab bus cables between pins 2 and 5  / Black and Yellow. Use this link below to calculate your cable loss.

***Note,  you must DOUBLE the length of your cable since you need to include the return trip.



 * @ 68°F or 20°C

** Results may change with real wires: different resistivity of material and number of strands in wire
