SimpleDigitalLocomotive 0.4 Beta 24

SimpleDigitalLocomotive will help you control digital model railway locomotives and function models via the serial port (RS.422) of a Mac...
This simple program can control digital model railway systems compatible to the 6050-syntax using the serial port of a Mac.
At the moment only locomotives and function models. Macs standard serial port was the RS.422 (8-pin) instead of the PC-worlds RS.232 (9-pin). After the release of the first iMac and G3 blue/white this serial port was no longer implemented by Apple.
Macs of today have only USB as their standard serial interface. The Digital Interface 6050 / 6051 has its own serial port (DIN 8-pin) and is shipped with a cable RS.232-to-Digital-Interface-6051. Other digital controlling devices (for example the IB) have built in a RS.232 modem-serial port.
A connection to the Mac is then possible with a standard Mac-modem-cable.

System requirements:
- USB-to-serial converter recognized by Mac OS X
- Cable serial-to-DigitalControllingDevice
- Model railway digital controlling device which is compatible to the so-called 6050-syntax
- Supported external devices: mrkl6021/6051, IB, Selectrix (and compatible).
