The Lighting Controller

We are running ShowXpress 6.2 on Windows 7 64-bit. I booted the PC run with unsigned drivers so the driver will work.

We have two different buildings with lighting.

One building has a newer setup with digital dimmer packs. We can successfully run the lights in that building with ShowXpress.

The other building has only analog dimmer packs. We cannot control the lights in this building. It is the same PC and USB Lighting Controller. Is ShowXpress compatible with analog dimmer packs?

We guess that your "analog dimmer packs" are driven with 0-10V signals (?)
In that case, you could find "dmx to 0-10V" converters on the market.
Please ask your lighting equipment supplier. He should be able to propose such equipment.
