PDI to PDI Splice kit

Lionel PDI cables can be thought of as RS232 Null Modem Cables.  If you are a youngster (in this case anyone younger than say 30), you may not be familiar with the legendary quirks of this vintage serial communications protocol.  The VERY short answer is that connecting two Data Terminals, for example, required flipping some wires in the cables.  "Pre-flipped" cables were called "Null Modem" because they allow you to connect a Data Terminal to another Data Terminal instead of to a Modem (which is another example of RS232 Data Communications Equipment).  These few sentences (poorly) describe more than 50 years of RS232 technology but the important thing is the Lionel PDI cables build on this legacy.  Connecting Lionel devices require an ODD number of PDI cables to work correctly.  If your PDI cable is too short you can't just connect two of them together.  This "PDI to PDI" splice pretends to be a very short Lionel PDI cable and allows you to daisy chain two Lionel PDI cables together while respecting the voltages and communications on the devices.

Note: This PDI to PDI Splice provides no power. It simply connects two cables together, making a longer cable.
