Cables terminating at mating connector must be secured with a cable clamp attached to one of the
mounting studs (see figure 2-10). Shields terminating at the mating connector can be attached to one of the
unused mounting studs with a locking terminal. Secure the cable clamp and locking terminals with 10-32
stop nuts. Tie wraps, cable clamps, locking terminals, and stop nuts are supplied with the hardware
package (see table 1-2).
Option Jumpers, as shown in figure 2-10, are installed on the mating connector assembly. The jumpers,
(22 AWG bus wire) are cut, as detailed in table 2-6, to enable/disable the different configurations. Jumper
configuration can be verified with a resistance check between pins 9 (CONFIG JUMPER) and 11 (-12V).
Simply compare the resistance measured between pins 9 and 11 with that shown in table 2-7. Table 2-7
lists the resistance value identified with each jumper configuration.

Figure 2-11 shows the WX-950 heading validation circuit along with a
typical connection of a navigational system (such as the King KCS55) that
provides a heading valid signal to the WX-950.
The shell and cable connector subassemblies are joined with two 4-40 stop nuts (provided with the
hardware package, see table 1-2).
