Installing the USB 1024ls Trigger & Closure Kit (discontinued product)
Overview
The USB-1024LS is low-cost, self-contained, USB-powered and very compact. When used as a trigger kit, it
offers up to 24 trigger inputs for your Simian automation system. When used as a closure* kit, it offers up to 24
TTL outputs for your Simian automation system to control outboard devices (there is no physical difference
between the Trigger Kit and the Closure Kit, it is just a matter of how it is configured and used).
As the USB-1024LS is a USB (Universal Serial Bus) device it is powered directly by your computer and is very
easy to install and configure (there is no need to open up your PC). All connections are via convenient screw
terminals at each side of the device.
Typically, triggers are controlled by closing contacts on your satellite receiver but can also be used to interface
your mixing console or start buttons with Simian and thus facilitate "remote control" of your Simian automation
software. Check the Components Unpack the USB1024-LS taking care to observe static precautions.
Closures* are signals used to control other devices (think of closures as an outgoing signal and a trigger as an
incoming signal). Outboard devices such as cart decks, cd players, transmitters, consoles, and more, use closures
to allow automation control. Some devices interface with 'dry closures' (IE: a physical relay with open and
closed states), an 'open collector' (IE: a solid state transistor with open and closed states), or a TTL signal (IE: a
voltage from ~0v off on to ~3-5v when on). When the USB-1024ls is set up as a closure kit, it generates TTL
signals. Ensure that you have the following:
