Quit all other programs and restart the workstation. Repeat Step 2 so that only the Inflexion I/O
Diagnostic program is running.
3. Select the channel that is to be tested.
Some workstations have more than one channel. There is a pull-down selection box on the
upper left-hand side of the Inflexion I/O Diagnostic window. The default selection in the
pull down is Board 1 (i.e., first channel). Refer to Figure 4-2. If more than one channel is in
the workstation, click and hold the pull down and then select the board (i.e., channel) that is
to be tested. The selection and identification of a board is as follows:
For workstations configured with 1 or 2 channels
• Board 1 -- This would be the first (or only) TARGA. This TARGA card is essentially the first
channel. If you are facing the back panel of the workstation and looking into the TARGA card
bay area, then Board 1 would be the TARGA card on the far left. If the workstation top is lifted
off, a TARGA card would be seated right next to the Serial 422 card. (Refer to Figure 5-1 within
the “Replacing Workstation Components” section of Chapter 5 for TARGA card locations.)
• Board 2 -- This would be the second TARGA card in workstations with more than one TARGA
card installed. This TARGA card is essentially the second channel. If you are facing the back
panel of the workstation and looking into the TARGA card bay area, then Board 2 would be the
second TARGA card from the left. (Refer to Figure 5-1 within the “Replacing Workstation Com-
ponents” section of Chapter 5 for TARGA card locations.)
• Board 3 -- This pull down selection is not used because workstations configured for two chan-
nels will have a maximum of 2 TARGA cards installed.
• Board 4 -- This pull-down selection is not used because workstations configured for two chan-
nels will have a maximum of 2 TARGA cards installed.
Important:
Loop back must be set up on the TARGA card channel to be tested. Refer to the “Setup
Before Testing” section above for automatic testing procedures.
4. Click the “Start Full Test” button on the Inflexion I/O Diagnostic window.
Brief descriptions of the tests are as follows:
• 3210 Components Test -- This test checks that the various components on the TARGA card are
functioning in a normal manner.
Note:
Depending on the model of the TARGA card in your system, the “3210” indication may appear as a
different number.
• Memory Tests -- This test performs extensive memory testing on the TARGA card.
• Hub Clock Rate -- This is a test to check that the TARGA’s “clock” locks to the oscillator.
• SDI Channel Tests -- This test loops a signal out of the SDI portion of a channel and checks that
the signal comes back into the card exactly the same.
• Codec Tests -- This test checks the encoding and decoding ability of a Codec by putting a fixed
image through the Codec.
