The requirements for the DCC Signal Generator are:
- output a +/- 5V DCC encoded signal to be converted to the +/- track voltage by an external power Booster.
- output a +/- 12V Programming Track Power supply encoding the DCC signal.
- provide an RS232 interface of at least 9600 baud which will be used to communicate with the host PC.
- function using the Control Protocol.
- maintain the bit sequence to repeatedly transmit to the Booster Signal. The bit sequence is 64 bytes in length (+64 bytes shadow = 128 bytes total).
- maintain the bit sequence to transmit to the Programming Track Power. The bit sequence is 16 bytes in length (a shadow is not necessary).
- have a reset button
- have an on/off switch.
- have 3 indicator LEDs; a 'System On' (green), an 'Overload' (red) and an 'Error' (red).
