Programming the device uses two
RS-232 compatible pins that can also
be used for full duplex operations at
19.2 Kb. The module accepts an unregulated voltage supply of 5V to 12V, as
the ARMexpress has onboard 1.8V and
3.3V regulators. The $149 evaluation
kit adds USB connectivity. When connected to a USB port, power is supplied
by the host PC. The evaluation kit will
also operate with the supplied external
power source. There is a generous five
square inches of prototyping area
which will accommodate 0.1” headers,
DB-style, or 3. 5 mm terminal blocks.
The board layout is also compatible
with the Hammond 1455J enclosures.
plus hours ( 11 years), LED lamps
operate more than 20 times longer than
the equivalent incandescent lamp. LED
lamps produce almost no heat and require 80%-90% less operating power
than equivalent incandescents, making
them as friendly to the environment as
they are to the operating budget.
Pricing for the super bright L200-
XIW Series LEDs is $18 for a package
of 10 LEDs. Large quantity discounts
are available. Availability is stock to
four to six weeks for special requirements. L200-XIW Series LEDs carry a
one-year limited warranty.

L200-XIW
SERIED LED
LEDtronics®
announces
the super bright
L200-XIW Series
LED. XIW series
Super Bright LEDs are significantly
brighter than standard LEDs. These intense LEDs come in the standard 5 mm
size allowing them to be useful and implemented in many common applications. They are ideal in applications such
as mini lamps, standard electrical based
bulbs, displays, theater décor bulbs,
telecommunications data products,
push button switches, safety area lighting, street lighting, medical equipment
lighting, or any application where you
need the warm glow of 3,000K color.
The XIW Super Bright LED comes
in a water clear dome lens housing. This
clear housing allows for a 20° viewing
angle that emits a beautiful and bright
3,000K warm white color. This tiny LED
puts out three times the normal light at
14,000 MCD while using only 3.2 to
4 volts DC. Other viewing angles are
available for OEM customers.
Solid-state design renders LEDs
impervious to shock, vibration, frequent
switching, and environmental extremes.
With an average life span of 100,000-

ETHERNET TO
DIGITAL
INTERFACE BOARD
ICS Electronics
has announced
a new Ethernet to
Digital Interface
Board for controlling digital devices
over a company network or over the
Internet. Called the Model 8013, this new
interface board provides 128 digital I/O
lines that the user can control from any
computer with an NIC interface or from
a TCP/IP network. Typical applications
for the 8013 are interfacing digital
devices, controlling relay matrices, or
acting as the Ethernet interface for a test
chassis or instruments.
The Model 8013 is an Ethernet to
Parallel Interface that provides 128 parallel I/O lines that can be configured as
inputs or outputs in eight-bit bytes.
Data transfer can be done by a combination of three methods depending
upon the needs of the devices connected to the 8013. First is by transferring data directly to or from a specific
byte, second by strings of data charac-
ters to or from multiple bytes, or third,
by setting or reading individual bits in a
byte. Handshake lines are provided for
synchronizing the data transfers or for
latching data into external devices.
The 8013 can also monitor 15
input lines and generate VXI- 11 Service
Request messages when an enabled
line changes state. The 8013 is an
IEEE-488.2 compatible interface that
responds to the 488.2 common commands and uses SCPI commands to
configure its digital interface. Users can
customize the 8013’s IDN message to
integrate the 8013 into their systems.
All settings are saved in Flash memory.
The Model 8013 is a VXI- 11. 3 compliant interface. VXI- 11 is a communication standard developed by the VISA
consortium in 1995 in conjunction with
the VISA Specification. VXI- 11. 3 is a
sub-standard that covers TCP/
IP-to-Instrument servers like the 8013.
Communication with the 8013 is via VXI-
11 RPC protocol over a TCP/IP network.
The 8013 can be controlled
several ways: The Model 8013’s
VXI- 11 Service can be accessed by
LabVIEW, VEE, Visual Basic, and C language application programs that make
VISA calls by selecting the 8013 as the
TCP/IP resource. Both Agilent and
National Instruments provide VXI- 11. 3
compliant VISA libraries. Linux, Unix,
and other programmers who do not
want to use a VISA library can access
the 8013’s VXI- 11 Service by RPC
calls from the application program.
The VXI- 11 Standard includes the necessary RPCGen header files for adding
RPC calls to any program. ICS
provides a free VXI- 11 keyboard program which lets users with a WIN32
computer interactively control the
8013 and other VXI- 11 instruments
without having to write a program.
ICS’s 8013 Ethernet-to-GPIB
controller has several unique features:
First, the 8013 is 100% VXI- 11. 3 compliant which is an open communication standard. The 8013 supports
reverse channel Service Request
messages to alert the client application
when an event occurs. The 8013 also
supports multiple clients as part of its
standard firmware. The 8013 is a
RoHS compliant assembly for use in
products aimed at the European
