11. Referring to Table 2, select the chip type (where available) and driver revision (where
available) using the buttons and pull-down list shown in Figure 4. (Note that the "Rev 1"
position should be used for FX909A and the "Rev 2" position (default) should be used for
FX919B and FX929B, if using the ES9000xx.EXE software).

The EV9000 motherboard’s two modem channels are now wired to ‘talk’ to each other and
the software is ready to execute modem operations.
12. Using the pull-down list near the bottom of the window, select Test 1: "PC Interface Test" to
initiate a test of the connection between the PC and the EV9000. This test continuously
reads IRQN A, IRQN B, Carrier Detect, and the HALT switch and logs any state changes to
the scrolling log area. Slowly press and release the EV9000 HALT switch and observe the
changes reported in the log. When you have verified the operation of the PC interface by
confirming the logging of HALT switch activity, click the
Stop
button to stop the test.
If HALT switch pressing and releasing actions are not logged on the PC, the PC to EV9000
connection is not operating properly. If this is the case, recheck your setup and review
Section 1.9. This test must be successful in order to operate the EV9000.
13. Click on the
Default
button to set default values for both channels’ Command, Control, and
Mode registers. The default Xtal frequency value is also entered. (The Xtal frequency value
which is displayed in the EV9000 software is simply a calculation aid for on screen display of
the configured data rate. The displayed data rate is calculated from the entered Xtal
frequency and the channel’s selected CKDIV value in the Control Register area. Changing
this value does not actually change EV9000 operation in any way. The modem Xtal
frequency is set by the user’s jumper selection of installed crystals.)
The EV9000 is now ready to execute a test.
