XCP0140A Headset Interface Box
The interface box allows the use of several headset accessories, such as the Startset II, Supra
headband-style monaural headset, and Supra headband-style noise-canceling headset. The headset jack
is assembled for mounting on the right-hand side of the console. Its use requires proper jumper
installation. (See Figure 4 for jumper locations.) If left-hand mounting is required, reverse the assembly.
The headset plugs into the modular-style headset jack (labeled
HEADSET/HANDSET ) on the rear panel.
See Table 6 for the headset modular jack pinout.
1. Verify the correct placement of the 2-position row jumpers PP1 and PP2.
2. Referring to Figure 4 for the programming jumpers on the main board, locate the 3 rows of jumpers
marked PP2, PP1 (center) and PP3.
3. Position the shorting clip from PP1 to PP2 to enable operation of the headset. This option must
also be enabled and the sensitivity of the headset microphone set in the User Parameters Menu as
described in the Console Diagnostics section. Refer to Table 6 for the headset jack pinout.
