The USB-CTR-15 is an ideal solution for adding portable, easy-to-install, counter/timer capabilities to any PC or embedded system with a USB port. This board is packaged in a small, rugged, industrial enclosure and features 15 independent 16-bit counter/timers. The unit is a true USB 2.0 device, offering the highest speed available with the USB bus. It is fully compatible with both USB 1.1 and USB 2.0 ports. The unit is plug-and-play allowing quick connect/disconnect whenever you need additional counter/timer devices on your USB port. The USB-CTR-15 can be used for a wide variety of measurement applications including event counting, frequency measurements, position measurement, pulse counting, pulse-width modulation and pulse generation. The OEM version provides just the board without the enclosure or external screw terminal board and is ideal for a variety of embedded OEM applications.
The USB-CTR-15 features five fully-undedicated industry standard 82C54 counter/timer chips. Each 82C54 provides three independent software programmable 16-bit counters. The maximum allowable input frequency is 10 MHz. I/O wiring connections are provided via an industry standard 50-pin IDC connector or via a removable screw terminal adapter board. A User Configuration Adapter board is also provided to assist in wiring the counters together. This allows for flexible yet easy counter concatenation/configuration.
The USB-CTR-15 is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board measures just 3.550 by 3.775 inches and ships inside a steel powder-coated enclosure with an anti-skid bottom.
OEM USB/104 FORM FACTOR
What makes the OEM option unique is that its PCB size and mounting holes match the PC/104 form factor (without the bus connections). This allows our rugged counter/timer board to be added to any PCI-104 or PC/104 stack by connecting it to a simple USB port usually included on-board with embedded CPU form factors such as EBX, EPIC, and PC/104 - especially important since many newer CPU chipsets do not support ISA and have plenty of USB ports. Future stacks will be using the extremely fast PCI Express bus which is essentially overkill for simple digital monitoring and control. The USB-CTR-15 OEM board can also be added into many pre-existing standard PC/104 based systems and enclosures. The OEM (board only) version is perfect for a variety of embedded applications. The board's pre-drilled mounting holes allow for installation using standoffs inside most enclosures or systems.
High Retention USB Connector
The ever-growing presence of USB in the industrial/military marketplace has driven the need for USB connections to be reliable, dependable, and unfailing. Gone are the days of loose USB connections. A type B USB connector is used on all ACCES USB/104 products which features a high retention design that complies with the class 1, Div II minimum withdrawal requirement of over 3 pounds of force (15 Newtons). This connector has an orange color-coded insulator to quickly differentiate it from standard USB connectors. Using these USB connectors increases reliability in your system and ensures a tight connection. For embedded OEM type applications, an additional miniature USB input header is provided in parallel with the type B connector.
