The V4+ is the smaller sibling of our V16+. They share the same operating system, chassis and electronics, but the V4+ is designed to control four devices. Like the V16+, it can easily handle several completely independent shows. It's a great example of why thousands of theme parks, museums, retail stores, restaurants, world Expos and visitor centers worldwide rely on us to provide the heart of their attractions.

Anyone who’s owned a PC takes the occasional crash and reboot for granted. With show control that’s simply not an option. That’s why our products use special, highly reliable hardware, connectors, and our super-stable ScriptOS real-time operating system. Some Alcorn McBride show controllers have been powered up and operating continuously for fifteen years without a reboot or power cycle. Try that with a PC!

Not only is ScriptOS extraordinarily stable, it’s also powerful, yet easy to use. Each controller is loaded with a script written using our Windows programming software, WinScript. You create your show's script by entering instructions in an English-like scripting language, much the same way data is entered into a spreadsheet. Once the unit is programmed, a PC is no longer needed.

Each script may contain as many as 256 sequences, which are completely independent. One sequence could handle a preshow, another the main show, and a third could simply monitor the entrance doors.

The V4+ has four RS-232 serial ports, brought out on easy to use DB-9 connectors; four may also be RS-422 or RS-485, and one may be configured for MIDI. WinScript comes with protocol files that speak the language of thousands of different devices. And if yours isn’t listed, it’s easy to create a new protocol file using our Protocol Editor. Your new commands become a permanent part of the ScriptOS language.

Our inputs and outputs are special, too. All discrete inputs are opto-isolated, providing protection against field wiring problems.

The V4+ uses self-restoring polymer fuses on each discrete output. Even a dead short in the field won’t harm them; they simply open the circuit until the problem is corrected, then almost miraculously heal themselves.

Using our WEBster Ethernet expansion option, the V4+ can be controlled, monitored, and downloaded across a local area network or the Internet. Control screens can be served to operator consoles throughout the facility or even across the Internet.

The V4+ can synchronize to a video frame clock. This means that – unlike competing controllers – we can guarantee frame synchronization of audio, video and control signals through your facility. No fancy programming or trial and error are needed. It simply works, every time.
