Some standard, off-the-shelf, data acquisition hardware will work with
Windows CE devices, both Pocket PC and embedded. See
Other Serial and Data Loggers. At this writing, the only other data acquisition
hardware that I have found specifically designed for Pocket PCs is described below.
This device appears to be a standard serial port, so, overall, it will be
accessed using the same techniques that would be used for other serial devices
(see Software).
Not all Pocket PCs will accept add-on hardware. Make
sure that your model is compatible before investing more money!

Overview
The DATAQ-CF2 is the first data acquisition device
in a Compact Flash format, allowing it to be used in standard hand-held
Pocket PCs.
The CF2 is more than just a data acquisition device, as it is supplied
with programs so that it operates like a number of dedicated
instruments. For field service technicians, the combination of the CF2
and a Pocket PC is easy to carry and has the advantage the recorded data
can be analyzed later on a standard PC.
Applications
• Field service and
repair
• Portable workshop test
• Portable medical instrumentation (e.g.
hearing tests)
• Integration with an embedded computer for
remote monitoring
• Custom instruments for OEM's
Hardware Features
• Type 2
Compact Flash Card
• 6 software re-configurable data
acquisition channels:
Four 24 bit analog inputs: 0 to 2.5V or ±2.5V
Two 12 bit analog outputs: 0 to 2.5V
Four digital I/O channels: TTL
• Differential or single-ended analog
inputs
• Up to 38 kHz sampling, multiplexed
• Burst mode sampling or single shot
• Digital channel can operate as:
Counter: 0.3 Hz to 26 MHz
Pulse-width: 36 nS to 12 hours
• Sensor 2.5V reference supply (up to 5mA)
• Operates from +5 Volt or +3.3 Volt
• Low power consumption: 34mA at 5 volts, 6
mA in sleep mode
• 32k Byte on board data buffer
• Looks like standard COM port for
programmers
Software Development Kit:
•
Now with
Labview 7 Express drivers
• Drivers supplied: VB, c++ (open source on
request)
Free programs included with every CF2 :
•
voltmeter
•
oscilloscope
•
frequency /counter / timer
• waveform
generator
• data
logger

| I have not used this hardware (it is too
expensive for me to get it on speculation). For
more information you can use these links (Strategic Test AB
in Akersberga-Stockholm, Sweden or Cambridge MA, USA).
or (ADPI in the US). 
An alternative may be to use a Compact Flash to PC
Card (PCMCIA) adapter. Software support, both driver and
application will be an issue. To date, I have seen no software
support for PC Card hardware, except for that furnished by National
Instruments for use with Lab View LV PDA software. See the
Software page for more information.
Here is an example of a CF to PC Card adapter. PCMCIA adapter
sleeves also are available at higher cost.

Product Description:
1. Converts any CF Type I / Type II slot into a PC Card slot
2. Flexible, durable, soft circuit board with rubber protection
3. Small, portable, and light weight
4. No driver necessary (the PC Card will need a driver,
though)
5. No external power necessary
Applications:
Wireless LAN cards, Memory Card Adapters, PC Card hard drives,
ATA Flash PC Cards, Modem cards, LAN Cards, GPS Receiver Cards, GSM
/ GPRS Cards, Communications Cards
**Warning**
Operating Voltage - Typical Pocket PC Compact Flash provides 3.3V.
The user should confirm if the PC Card operating voltage is
compatible with the Pocket PC.
Power Consumption - Typical Pocket PC Compact Flash slot can supply
up to 500mA of current. However, some PC Cards may require as much
as 700-1000mA.
Driver Availability - The user should first verify if the driver
support is provided by the PC Card vendor to use with Pocket PC.
Package Includes:
Compact Flash to PC Card Adapter X 1 (link
to seller about $20 plus shipping and handling charges) |
