NCE AIU-01 Auxiliary Input Unit

NCE AUI-01 DCC Auxiliary Input Unit.

The Auxiliary Input Unit (AIU) provides a means connecting external devices such as switch contacts, Block Detectors, or other sensors to the Command Station.

These external devices can be anything that supplies an electrical connection between the input pins (1-14) and the pins marked “GND” in Figure 1. These connections can then be read by a computer through the RS-232 port of the command station using the RS-232 commands on page 4 of the manual.

The 14 LEDs provide indication of which input is active. An LED will light when its corresponding input terminal is connected to ground. This provides an easy means to test whether the block detector or other device you have connected to the terminal is working.

The AIU is a Cab Bus device (thus it must be plugged in to the cab bus using the cab bus connectors) and must be used with another Cab Bus device (Power Pro, Power Cab, USB interface etc.)
