Introducing the USB-1096HFS

Overview: USB-1096HFS features

This user's guide contains all of the information you need to connect the USB-1096HFS to your computer and to the signals you want to measure or control.
®
The USB-1096HFS is supported under popular Microsoft fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-1096HFS provides 96 digital I/O lines, high output current, and one 32-bit external event counter. The USB-1096HFS is powered by an external +9 V unregulated power supply that is shipped with the board. A USB cable is also included.
Power OUT and USB OUT connectors let you power and control multiple MCC USB Series products from one external power source and one USB port in a daisy chain fashion. Depending on your load requirement, daisy chained boards may require a separate power supply.
Windows® operating systems. The USB-1096HFS is
You can connect your field wiring directly to the board's screw terminals. The 96 digital I/O lines are available in four independent port groups. Each digital port group is divided into two 8-bit ports and two 4-bit ports, and is a discrete emulation of 82C55 mode zero operation. You can configure each port independently for either input or output.
The USB-1096HFS outputs are high-drive TTL that can source 24 mA and sink 64 mA. Additional buffering is typically not required to drive external devices.
Each digital port has an associated pull-up resistor to drive the ports high during power up and reset. You can optionally configure this resistor for a pull-down configuration. All I/O bits are set to input mode on power up and reset.
The USB-1096HFS also provides 50-pin mass termination connectors. For OEM's who wish to use the mass term connectors, the enclosure needs to be removed.
The USB-1096HFS is shipped in a rugged metal enclosure that you can mount on a DIN rail or on a bench (see Figure 1-1).
