Step 19:
Strip ¼” from the end of each wire as shown. 
When this is done, they are ready for termina-
tion in the Bulkhead Box. 
Step 20:
Slide all of the prepared wires and the video 
cable through the 1” reducer. Then carefully 
pass all of the prepared wires and the video 
cable through the hole in the front of the Bulk-
head Box.  
Step 21:
Slide all of the prepared wires and the video 
cable through the lock nut, and secure it to 
the 1” reducer as shown
Step 18:
Slide the outer insulation of f,...

12 Step 22:
Connect the wires from the main sensor cable 
to terminal blocks 
J6, J7, J8, and Video In 
using the drawings provided at the end of this 
manual for guidance. 
You can also refer to the graphic inside the 
cover door of the Bulkhead Box for a color-
coded guide, or the Connections Quick Refer-
ence table on page 18.
Step 23:
Power input - connect the wires from the 
system power cable to 
J5. The cable 
ends are prepared using the same proce-
dures used in the previous steps.

14 NMEA INTERFACE
The Voyager II has the capability to “listen” to (or take commands from) radar, GPS or other devices 
using the National Marine Electronics Association (NMEA) 0183 Protocol. The NMEA 0183 protocol 
is a combined electrical and data specifi cation for communication between marine electronic devices. 
Additional information regarding the protocol can be found on the NMEA web site: 
http://www.nmea.org/ 
According to the NMEA protocol, the Voyager II is known as a listener, and another...

15 NMEA Interface Wiring
The connection from the other NMEA device must be routed through one of the JCU cable glands lo-
cated on the bottom wall of the Bulkhead Box.

Serial Communications
The JCU connections on the Voyager II Bulkhead Box are daisy-chained together, as shown in 
the fi gure below. Each JCU slot is 
interconnected to the appropriate terminals in the previous slot 
within the Bulkhead Box 
Any signals/data that come through JCU slot 4 are then...

16 Connector Slot
The NMEA talker device, whether it uses RS-232 or RS-422, should be connected to the fi rst 
unused JCU slot. The NMEA interface card comes installed in slot J4 by default. If used, the card 
must be moved to the JCU slot af ter the last active JCU. For a system with one JCU, the connec-
tion should be made to the J2 slot, as shown in the previous example. For systems with 2 JCUs, 
the connection must use the J3 slot. For a system with 3 JCUs, the connection must use slot J4.
Figure 2:...

17 When connecting to the adjacent slot, attach NMEA “A” and “B” signal wires to connector terminals 
1 and 2 respectively. These terminals are interconnected to the appropriate terminals in the previ-
ous slot within the Bulkhead Box. No additional jumpers are necessary. Refer to the drawings at the 
end of the manual for more information on specifi c pin designations on the terminal blocks.
Pigtail Connection
For a Voyager II confi guration with 3 JCUs and a NMEA interface, all four JCU slots are...

18 NMEA Messages
The Voyager II recognizes (or responds to) a subset of NMEA 0183 messages (also called 
sentences). The standard NMEA 0183 messages required for Voyager II integration are as fol-
lows:
•  HDT – Heading, True
•  GGA – Global Positioning System Fix Data
•  GLL – Geographic Position, Latitude/Longitude 
•  RSD – Radar System Data
•  TTM – Tracked Target Message
•  BWC – Bearing and Distance to Waypoint
•  VHW – Water Speed and Heading

Caution: 
A non-isolated connection to external electronics may result in damage to the Voyager Camera 
System. Use electro-optical isolators when needed in accordance with sound marine electron-
ics practices
