This system is a PWM type of system so it will work with incandesant or LEDs.
The baud rate is 115,200 bps and the I/C is running at 40 MHz.
The system consists of:
12 VAC wall wart transformer
One (1) PC Interface
Four (4) 32 Channel Field Modules
Thirty Two (32) 4 Channel SSR's
All 128 channels of data is sent to all four modules. The field modules identify their respective module numbers with hardware jumpers and only accepts the data it needs.
The plugin allows you to run 1, 2, 3, or 4 modules. 32 consecutive channels are sent to a module. The user selects the starting channel of the 32 channels.
The PC interface connects to a 9 pin RS-232 serial port on the PC. The RS-232 data is converted to RS-485 and sent to the field modules. Since the data is transmitted via RS-485, the distance of the cable between the PC Interface and the field module(s) can be a several hundred feet. I have not tested that yet, I'm working on testing ~ 150 feet.
Below is a diagram of the architecture.
Below is a picture of the PC interface.
Below is a picture of the 32 Channel Field Module.
The connections for the SSR's are right for Sean's SSR's.
The system is capable of bi-directional communication.
