4. SIO(RS-422, RS-232C)Communication test
This program performs the SIO(RS-422, RS-232C) test.
Perform the test with the loop-back connectors attached to RS-232C(EDL Port) and RS-
422(VTR, SWer, MIXer, CONPANE Port) on the rear panel.
After testing the DPR on the SIO-26 board, the loop-back test is performed.
When the following message appears after running the Manual test, press the Return
key to return to the selection menu or press the space key to rerun the test.
4.SIO(RS-422,RS-232C)Communication test ------ !! OK !!
PUSH RETURN KEY (PUSH SPACE KEY TO REPEAT)
When an error is detected during the DPR, address and data where the error was
detected appear with the NG display as shown below.
