Using the USB-1024ls
Your USB-1024ls is now fully configured and ready to use. To set up trigger sets or use the RELAY macro (in
Simian), refer to the sections regarding Trigger Sets (and in Simian, Macros) for instructions on setting up the
desired functionality of each trigger/Closure*.
* Note regarding 'closure' functionality:
When the USB-1024ls is used as a closure kit, it offers up to 24 TTL outputs, each channel providing a 0-.05mv
signal when off, or a 3-5v signal when on) - not a dry relay closure capable of sinking current or an open
collector. To use the USB-1024ls as a relay device, use relays with a primary coil voltage of 3-5v connected to
each output. To use the USB 1024ls as an open collector device, use transistors connected between the USB-
1024ls and the device you want to control (for instance, connect each of the USB-1024ls' output pins to a current
limiting resistor, which is then connected to the base of an NPN transistor).
