I'm working on the same thing right now. I have 3 "topotables" I'm
For these I'm using 2 differernet USB IO cards:
USB-I2CIO USB-to-I2C with I/O Interface Board
USBIO24 MK III USB-to-24xI/O lines
For testing I have one of each, with wires going over to their own
breadboards with LEDs that I can switch on and off.
Both these boards come with documention for VB. So I wrote activeX
components that I can load into Director, send commands to turn the lights
off and on etc. All working fine. I could not get any of the xtras I found
to work, and I tried about 6 different ones.
For me, I just have to go into the installation with the PC and hook my USB
to the modeler's table switchboard and it will turn the lights on and off.
The modeller has built a separate switching system, with the USB cards which
go into some thingys which switch relays on and off for the power required
by the topotables lights. The power out of the USB cards is only 3 to 5
volts and not enough to power the actual lights on the table.
Pretty fun stuff!
What I'm doing is I'm using
