SECTION SIX: Interfacing the 958 system
958 Installation Manual, Rev. A1

Connecting two Northstar units
You can connect two 958’s (or a 958 to a 957) and then transfer one of the unit’s waypoints and
routes into the other. To connect the 958’s, you must fabricate an interface cable and terminate both
its ends with the supplied 6-pin solder-cup style cable connectors. This data-transfer cable is not
included with the 958. You must select a cable; use only shielded, twisted pair.
You can also connect a 958 with a Northstar 952, 951, or 941, also using your own data-transfer
cable. Each 952, 951, and 941 that you want to transfer waypoints and routes to or from
must
be
using software version 3.12 or higher.
Assembling the cable
To assemble the cable
:
1. Cut the cable to the desired length.
2. Slide the following parts onto each end of the cable, in the following order:
•
connector backshell
•
rubber-strain relief boot that fits inside the backshell
•
twist lock (also known as a quarter turn), ensuring that it’s facing in the correct
direction.
3. Trim and prepare the wires for soldering to the connector body.
4. Terminate the cable, as described below.
Terminating the cable
To terminate the cable:
1. Terminate and solder the appropriate wires to the appropriate pins:
•
For wiring two 958’s or a 958 to a 957, see Figure 17 on page 32 and Table 9 on
page 32.
•
For wiring a 958 to a 952/951/941, see Figure 18 on page 33 and Tabl e10 on
page 34.
