MFCB Connections
One side of the cable box has two power ports.
Although labeled “Power” and “Remote
Display”, they are identical and can be used interchangeably. The other side of the cable box
has a power post for connecting the transmitter wire; the serial port is only used with the SST
(steering tool) system.
Multi-Function Cable Box (MFCB)
Although the DC power cable used to power a freestanding multi-function display through the
power port on the drill rig can power the cable box, DCI recommends connecting the cable
box directly to an
independent
automotive battery or DC power source
other than
that on the
drill rig to avoid voltage disruptions and current draw variations that may interrupt power to
the transmitter.
