Adapter Testing
• Boot your PC from the floppy disk labeled "Diag
(Boot)". After the boot DIAG utility will start
automatically to search for installed adapters.
• Choose "General Test" from "Test" menu. This
will check main communication circuits of the
adapter (bus test) and then start an internal test
of all channels. The test should find no errors
(several CRC errors are only allowable in the
beginning of the test because of the sync
adjustment).
• To check external signal circuits go to "Channel"
menu, select the necessary channel number
("Select Channel..." row), connect an external
contactor (supplied with the adapter) to the
connector of the channel so selected, and launch
an external loopback ("External Loopback"
row).
• If the connected communication equipment
supports the loopback mode you can use the
latter for cable testing as well as for
synchronization instead of the contactor. To do
that switch the external equipment to the
loopback mode and start an external loopback
of the channel ("Channel" menu, "External
Loopback" row).
• "Setup" menu is used to change sync mode,
speed, test data type, etc. "Channel", "Adapter",
and "Test" menus are used to test single channels,
all channels of the same adapter, or all adapters
simultaneously.
