There are a number of possible causes for a communications failure. These are listed
below.
1. Cable not connected or incorrect cable type. The cable should be a fully-populated
Centronics printer port cable.
2. Incorrect printer port. The evaluation board requires that the printer port has bi-
directional capability. Acceptable types are PS/2, EPP and ECP.
3. Correct Printer Port but bidirectional capability not enabled. It is possible that a
bidirectional printer port can be set to be unidirectional mode in the PC BIOS.
The user should consult the PC manual for instructions on examining the BIOS
4. Incorrect Printer Port Address. There are three possible addresses for a printer
ports and the one fitted to a users PC may not be the same as the default address.
This can be changed using the Printer Port menu item.
The AD73360(L) may not be acquiring samples. Verify that the correct link positions
are selected. Also verify that the SE and RESET are being brought high and that the
the AD73360(L) is giving out the correct number of Frame Syncs per sample period
once it is in program mode.
Verify that the AD73360(L) is receiving an MCLK signal.
