Page 1 of 3 USB interface
This USB interface board receives the orders coming from the PC on the USB
bus and send them to the target module which can be a PWM driver, or a Device
Controller or a Train Detector.
It also polls the PWM and Train Detector modules to scan for the train presence.
The USB Interface module has a single USB bus connected to the PC and it can
supervise one or two serial busses for communicating with the control modules.
The second bus is optional and it is only recommenced for controlling layouts
with more than 25 modules.
Here is a picture of the USB interface board wired in its minimal configuration.
