The Ether I/O 24 from
Systems is a UDP/IP
controlled digital Input/
Output module. The module features three eight-bit ports with
5V level signal lines. Each of the 24 lines
can be independently programmed as
either an input or output.
The module connects to any
Ethernet network supporting the TCP/IP
protocol suite and can communicate
with any point on that network. By
connecting with an Internet Router, the
device can communicate with any Internet connected device. Features include:
ports and transmit changes
directly to another Ether I/O 24
module without host connection or to any Internet port by
• On-board EEPROM allows
all ports to power up in a user
• Programmable fixed IP or dynamic
IP assignment from a DHCP server.
• Small packet size and connection-less protocol allows for real time
sensing and control.
• Can be connected to a wireless
network gateway or access point for
• Supports ARP, BOOTP, DHCP,
ICMP, and UDP/IP protocols.
• Low power consumption; only
1.1W fully operational.
• Industry standard 10BaseT Ethernet
interface with an industry standard
RJ- 45 connector.
• 24 independently programmable
signal lines with configurable CMOS,
TTL, or Schmidt Trigger thresholds and
programmable pull-ups per line.
Applications include home or
industrial automation, digital input and
output from any networked PC,
remote data acquisition and/or alarm
monitoring by network or Internet,
PC-controlled machines and distributed machine I/O, and remote lighting
/power control and/or monitoring.
• Easy connection by three 10-way
box headers to suit low cost, standard
IDC or crimp connectors.
• Integrated switch mode voltage
regulator allows power from any
8-32V DC power source.

• Uses 5V 500 mA output to power
external interface boards or sensors.
• Compact module measures only 72
mm x 72 mm x 24 mm.
• Advanced configuration allows the
modules to automatically scan the input
ARMexpress — the
fastest Stamp compatible module. As the
name implies, a Philips LPC2106 ARM
CPU running at 60 MHz has been
mated with a built-in Basic compiler to
achieve high performance in a small
package. The 600 mil, 24 pin pluggable
device is priced at $69.
Because the Basic source is compiled, the performance exceeds 10 million Basic lines per second, and update
rates for control of the 16 TTL compatible I/Os exceeds 1 MHz. This performance is comparable to programs written
in C. 40K is available, enough for 3,000
lines of user program, and 40K for data.
4K of Flash is also available for writing.
In addition to the native 32 bit integers,
string processing has been added. This
includes concatenation, STRCMP,
LEN, LEFT, and RIGHT functions. The
real time clock is also integrated into
the Basic with pre-defined variables
SECOND through YEAR. In addition, a
free running microsecond TIMER is
available to the user.
The use of Basic makes the module quick to master and easy to use. It
is perfect for solving the problems of
building a quick prototype, coming up
with the glue for factory automation
problems, as a flexible lab bench tool,
or fun for hobbyists. The user interface
will integrate with your favorite text editor, and the simple but intuitive control
program is easy to learn. The compiler
is incremental and gives the feel of a
scripting tool. It also supports displaying variables immediately and running
single statements immediately without
recompiling the Basic program.
To ease control of external devices,
support for the popular SPI, I2C,
1-Wire, and ASYNC protocols are
built in. This allows control of serial
peripherals at rates up to 800 Kbits/sec.
In addition, library support includes
PWM, SHIFTIN, SHIFTOUT,
PULSIN, PULSOUT, RCTIME, and
FREQOUT. These functions all have a
one microsecond resolution.
