Typical socket pinout and definitions

NOTE: current limiting resistors are on the IOX boards.

LED Wiring

All LEDs will be wired in a common anode arrangement where LEDs are "pulled low" to enable them.

Socket Construction Standards

Test Signal

• 08 Feb 2019 James Hughes to build simple 3 over 3 test signal. Ended up ordering a 12pk of quick, PDB based signals

Justin to build a signal test mast

• Doesn't need to look prototypical
• mounted on standard 8 pin socket
• 2 tri-color signal heads on one mast?
