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.

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

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
