The Phone Company had to make "ring voltage," normally 90VAC at 20 cycles, using special Ringing Voltage Generators. A regular electric motor drove a magneto (similar to the ones that were cranked by hand on phones), to provide ringing voltage.. No. 3 Power Cable 2 pin female. No. 4 1 2 pin IB3 – Drivers Box connecting cable.: IB3 connections: Male power connection on the IB3 Box (No. 3) 12 pin connections on the IB3 Box (No. 4). Turnout Control. For Information On Wiring turnouts, Go To the Section On Wiring Turnouts. For Introduction to Turnout Control Options, Go To DCC for Beginners. SUGGESTION #14-2: Use DCC Controlled Turnouts and Eliminate Control Panels! Call me a gadget hound, but this is one of my big attractions to DCC — you don't need any control panels!.

WARNING: On radios with more than four pins you may often find that there is a voltage present on one or more of the other pins.
