4. Route another 3-conductor cable through the fitting into this
junction box, and attach wires to the TB2 terminal: black wire to B
terminal, white wire to W terminal, and red wire to R terminal.
Connect the cable shield wire to the Shield terminal between TB1
and TB2.
5. Repeat Steps 3 and 4 until all junction boxes for the vessel are wired
together.
6. Route the cable from the last junction box through conduit/cable
tray to the signal processor. Refer to the signal processor manual
for wiring the junction box to the signal processor. One vessel takes
up one channel in the signal processor — the channel shows the
average value from all the Microcells on the vessel supports.
Note
Ground the cable shield only at the signal processor.
