Power Setup
The cable box has two identical power ports shown in the introduction. The ports can be used
interchangeably; one needs to be connected to the DC power source and the other to the remote
display’s DC power port. The power ports are keyed to match the power cable connectors. The power
cables are installed in the same way as the remote display’s standard DC power cable. See “Connecting
the DC Power Cable” in the Basic Instructions section of your MFD/FSD remote manual.
The cable box may be powered by the drill rig’s battery using the standard DC power cable provided with
your remote display. However, DCI recommends powering the cable-box directly with a standard 12-28 V
DC automotive battery.
For bores shorter than 1000 ft (305 m), one 12-V battery will suffice. If the bore length increases beyond
1000 ft (305 m), an additional battery may be added in series (see diagram).
