  stanley82August 15, 2008

  It's not what I was looking for.

• Does everything you need to troubleshoot serial interfaces

  SCBuckeyeDecember 14, 2006

  Pros

  If you have ever troubleshot serial communications between devices and not used a protocol analyzer, you should try this. Combined with a breakout box they tell you everything that is happening. They make a huge difference, and this does all you need. It was tested by me and worked with XP and 2 cheap USB to 9 pin serial cable adapters you can find anywhere. I tested in the single port passive monitor setup, 2 port passive monitor setup, and the NT mode which allows you to monitor a port in use on the same PC. All worked fine. The interface was very easy to use, set up, and follow. <p> <p>With the cable below this will monitor signals but not send any, so it can be used to passively read what is being transferred between 2 other devices.

  Cons

  They did not provide the pinout for the monitor cables, so here it is. Buy 2 25 pin jumper boxes you can find at Radio Shack (used to make custom adapters for serial cables). Cut a hole in the top of each to pass wires thru. <p> <p>Jumper 1 adapter straight thru (pins 1-1, 2-2, 3-3. etc.)and label as -LINE-. This will be placed in the line being monitored and referred to as the line adapter. <p> <p>Choose 1 port on the other adapter to be the DTE monitor. Wire pins (from line to DTE monitor) 2-3 (TX-RX), 4-5 (CTS-RTS), 7-7 (common), 20-6 (DTR-DSR), 22-8 (CI-DCD) <p> <p>Choose the other port to be the DCE monitor. Wire pins (from line to DCE monitor) 3-3, 5-5, 6-6, 7-7, 8-8 <p> <p>Do not connect any of the DTE monitor pins directly to the DCE monitor pins. <p> <p>Super glue the 2 adapters together, with the ports set 90 degrees apart from each other. Connect to the PC used to monitor the lines using only straight thru adapters and cables.
