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.

SOFTWARE
The USB-CTR-15 is supported for use in most operating systems and includes a free Linux (including Mac OS X) and Windows 98/NT/2000/XP/2003 compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also incorporated is a graphical setup program in Windows. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes example LabVIEW VIs. Embedded OS support includes Windows XPe.

ACCESSORIES

The USB-CTR-15 is available with optional cable assemblies, screw termination boards, and an optional external AC/DC power supply.

Specifications

Counter/Timers

Type: 82C54-10 programmable interval counters
Output Drive:
- 2.0 VDC min., source 32 mA
- 0.55 VDC max., sink 64 mA
Maximum Input Frequency: 10MHz
Input Gate: TTL/CMOS compatible
Clock: On-board, 10 MHz crystal-controlled clock
Active Count Edge: Negative edge
Minimum Clock Pulse Width: (input characteristic) 30 ns high, 40 ns low
Minimum Divisor: divide-by-2
Maximum Divisor: divide-by-65536 (16-bits, load value "0")
Timer Range: 16 bits

Bus Type

USB2.0 high-speed (480 Mb/s)
circa 4000 transactions per second

Power

Basic unit: 60mA typical (no load); 12mA with max counter transitions
+5 VDC from the USB bus or external power supply depending on user configuration

The USB bus is specified to provide 500 mA to most desktop environments. This gives you 440 mA available (500mA -60mA = 440mA). If using more than a total of 500mA, use optional 9 VDC (on board voltage regulator outputs +5 VDC to card) external power supply and remove VUSB jumper and place jumper on VEXT. Then plug in external power before plugging into USB port . This option will give you a total of 1000mA available.

+5V resettable fuse at 0.5A located on connector
