6.5.7 AC Charger/Power Supply Troubleshooting Test
If the system setup includes an AC charger/power supply connected to the
optional equipment enclosure, and it is not supplying the required voltage to the
NGC unit, test the AC charger/power supply.
6.5.7.1 Instructions
1) Check the input AC voltage to the enclosure power supply. Be certain the
primary AC voltage is correct.
2) If the primary input AC voltage level is correct, and there is no DC output from
the power supply, replace the F1 charger fuse (see Figure 6-3
).
3) If the fuse is not faulty or there is no charger DC output voltage after replacing
the fuse, replace the AC charger/power supply.

6.6 Troubleshooting Communications
These troubleshooting procedures are applicable to an NGC8200 with an installed
radio in the optional equipment enclosure. Use Figure 6-4
as an aid for
troubleshooting communication problems. The three basic types of radio
communications that can be used between the NGC and a radio receiver are:
• RS-232 Communications (see Table 6–4 for pin Configurations)
• RS-485 Communications (see Table 6–6 for pin Configurations)
• RS-422 Communications (available, but not detailed)
The radio/modem may be powered one of two ways: always on or switched. The
specific system setup will determine what steps are needed to power the
radio/modem.
