The USB-1408FS is a USB 2.0 full-speed, device that is supported under popular Microsoft Windows
operating systems. The USB-1408FS is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-1408FS features eight analog inputs, two 12-bit analog outputs, 16 digital I/O connections, and one
32-bit external event counter.
The analog inputs are software configurable for either eight 13-bit single-ended inputs or four 14-bit differential
inputs. The 16 digital I/O lines are independently selectable as input or output in two 8-bit ports. The 32-bit
counter can count TTL pulses. A SYNC (synchronization) input/output line allows you to pace the analog input
acquisition of one USB module from the clock output of another.
The USB-1408FS is powered by the +5 volt USB supply from your computer. No external power is required.
The USB-1408FS is shown in Figure 1. I/O connections are made to the screw terminals located along each side
of the USB-1408FS.
