4.6 Tests
The EV9000 software includes several automated tests. This section describes their function and
operation.
4.6.1
Test 1: PC Interface Test
4.6.1.1 Application
Verifies the proper operation of the PC to EV9000 interface and the ability of each of the modems
to respond appropriately to a command.
4.6.1.2 Description
This test operates in two phases. The first phase primarily tests the parallel port interface
between the EV9000 and the PC. The second phase tests the ability of each modem to respond
appropriately to a command.
The parallel port phase of the test continuously reads IRQN A, IRQN B, HALT Switch, and Carrier
Detect and logs any state changes to the scrolling results log window. After starting this test,
slowly press and release the EV9000 HALT switch and observe changes in the log window. If
pressing and releasing the HALT switch is not logged on the PC, the PC to EV9000 connection
has not been successful. In this case, recheck your setup and review Section 1.9. After you have
verified the operation of the PC interface by confirming the logging of HALT switch activity, click
the
STOP
button to advance to phase two of the test.
The modem response phase of the test:
1. Writes to the mode and control registers of a modem,
2. Writes commands to the modem, and
3. Observes whether an appropriate interrupt response is received in a reasonable time.
Both phases of this test must be successful in order to operate the EV9000.
