3.3 VIPER MLV IA SYSTEM SELF-TEST
Self-test must be performed prior to any operation on the aircraft (Figure 3-3) and after any repair activity on the Viper MLV IA. Self-test can be performed in the either mode of operation. The two tests that are performed are (Figure 3-4):
1. Interface Adapter - Test the internal Programmable Input/Output (PIO) board, the 1553-interface board, and external connections through J1, J2, J3, J4 and J5 connectors.
2. Cables - Test one or more of the interface cables. Selecting the specific system for that cable interface can also test an individual cable.
