ASI v2 Operations (PRELIMINARY)
Operational Mode Selection Matrix
The matrix below shows all the Operational Modes and their corresponding DIP Switch settings
(but without expanding the 3 Transmission Preamble Length switch settings). In the matrix “x”
means “don’t care” and “p” means preamble length time setting switch input.

Diagnostic Mode, Production & Field Testing, DIP Switch Selection Settings
CAUTION – the diagnostic tests are designed to be run WITHOUT any transmitter connected to
the ASI board. Although all tests are designed so as not to turn the “PTT” and “SW+12” line on
simultaneously, it may be possible to damage a transmitter (or ASI board) if some of the
Diagnostic Mode Tests are entered with a transmitter attached. It is prudent to disconnect any
transmitter prior to running diagnostic tests.
Remember that for changes in DIP switch settings to be effective the ASI must be RESET after
new switch settings are entered. A RESET is done by either depressing the RESET switch on
the ASI board for 5 seconds or by powering the ASI board off for at least 90 seconds.
Once a diagnostic routine is begun, it runs continuously (unless an internal error occurs). In
order to exit a diagnostic test and enter a different test, or to return to an operational mode, the
ASI board must be RESET. A RESET is done by either depressing the RESET switch on the
ASI board for 5 seconds or by powering the ASI board off for at least 90 seconds.
