What are the specifications of the cable for the Vernier Photogate?

The cable that comes with the Photogate, order code VPG-BTD, $45, produced since July 2003, has a six-conductor clear plastic telephone-style connector at the photogate end, often referred to as 6P6C, for "6 position, 6 conductor." The cable looks much like the cable that came with the older photogates, but the old cables had a four-conductor telephone connector.

A four-conductor cable will work with the Vernier Photogate, but the auto-ID function won't work because the necessary connection is not made.
