If the you get a verbose output like this, check to make sure that the self test
loop-back board was connected properly.
N o t e
You can check the 50-pin ribbon cable by connecting it between the
emulation controller and loop-back board and performing this test.
Test procedure for the emulation probe
Procedure
1
Dismount the power supply from the emulation controller.
2
Connect the emulation probe and the emulation controller.
Connect the 50-pin ribbon cable and AUX power cable.
3
Plug the demo board into the 177-pin PGA connector.
4
Set the DIP switch on the demo board to "TEST MODE."
5
Set all of the DIP switches to CLOSED.
This is standard RS-232 at 9600 baud which can be connected directly to a 9
pin RS-232 interface that conforms to the IBM PC-AT 9 pin standard.
6
Connect a coaxial cable between the BREAK IN and TRIGGER OUT
BNCs.
Connect the power supply to the emulation controller.
8
Enter the pv command through the terminal emulator.
After testing, return the DIP switch on the demo board to the"DEMO MODE."
The results on a good system are as follows:
