STEP #2 – Use a terminal strip to connect the Hub Power Cable to the NavNet 12VDC
Output Cable. Choose a “Primary NavNet” Display to use for Hub Power. This display will
have to be turned on for the Hub to work!
Use the “DATA3” or “DATA4” 7-Pin (NMEA In, RS232 I/O, 12VDC Out, Buzzer) data port on the
rear panel of the NavNet Display to power the hub. The proper cable for these ports is the
000-144-418 Cable:
000-144-418 NMEA In/RS232C Out/Buz. Out/12VDC Out Cable
The “DATA3” and “DATA4” 7-Pin data port PIN ASSIGNMENTS are listed below and the wire
colors for this cable are also listed.
(WARNING! - The “DATA1” Port Pin Assignment is NOT THE SAME as the “DATA3” or
“DATA4” Port Pin Assignments. Be Careful!)
000-144-418 Cable Color Code
PIN #1 – TD
WHITE
RS232C “+” to PC or NMEA Output

SHIELD
USE BARE SHIELD FOR +12VDC & RS232C GND

Hub Power Method #2 – Power the Hub from Ship’s 12VDC through a Fuse or Breaker
The Ethernet 10BASE-T Hubs we suggest will have no problems when powered from
12VDC Power through a breaker. If you have a larger 24VDC vessel, use a 24VDC-12VDC
Voltage Converter or power the hub directly from the ship’s stable AC source using the
supplied 110VAC Adapter.
NavNet display
Use 12VDC output from DATA3 Port
on 7” LCD & 10” CRT Displays or
DATA4 Port on 10.4” LCD Displays

In this installation, the power to the hub comes from the NavNet Display
