Correct, but it seems the transmit side is the one that gets abused and loses signal strength most often.

So, I am in the repair business.  I can't say the transmit side works great, sorry it still doesn't work for your layout.  The fact is, I get a tiu not working I have to run the transmit test first.  If that is all good, or not and repaired, I then have to run a end to end test on receiver using a PS-2 board.  Interesting enough I have found bad receiver can adversely effect Transmit strength too. 

The tool is a great help, but not the end all for validating TIU operation.  G

Above you mention testing the TIU receiver portion with a PS2 board, can you describe this test procedure?  At the club, we are currently running 8 TIUs and every so often I check the TIU transmit side with a scope or the TIU port tester tool.  At the same time, I would also like to test the receiver side to see if there are any issues with the TIU.

Thanks,
