The USB-5201 can be configured via the USB port using the included InstaCal
Software in a matter of minutes. The data can be analyzed and charted using
our powerful TracerDAQ software, available in a full range of options--from
no programming to graphical programming to custom programming.

| Standalone Power Supply |
USB Power Adapter
2.5 Watt USB Adapter with Interchangeable Plugs
(Includes Plug for USA) |
| Memory Card Type |
64 MB CompactFlash® |
| Storage Capacity |
2GB Maximum |
| File System Format |
DOS FAT-16; the memory card
must be formatted by the device prior to use for
logging. The device only creates 8.3 file names and
a flat directory structure ( no subdirectories).
The memory card is readable by Windows operating
systems after device format/use. |
| Logging Rate |
Minimum 1 second between
entries, Maximum 232 seconds, 1 second granularity |
| Data Items Logged |
Timestamp,temperature or
raw reading from selected channels, state of DIO
lines, CJC Sensor Readings |
| Logging Start Methods |
Configurable:
1. Start Logging on Power Up - Logging begins 5 seconds
after power on to allow hardware to settle.
2. Start Loggin on Button - Device is idle on power on.
Press and hold button until LED comes on to begin logging.
The first sample will be taken 1 second after LED comes
on unless less than 5 seconds have elapsed since power on.
3. Start Logging at Specified Time - Device is idle until
the real tme clock indicates the time is equal to or
greater than the specified time, at which time the LED
with come on. The first sample will be taken 1 second
after LED comes on unless less than 5 seconds have elapsed
since power on.
NOTE: Data Logging is not allowed when the device is attached to an active USB bus due to processing limitations. The device must be connected to the standalone pwer supply to perform data logging.
|
| Logging Stop Methods |
Stop on button Press - To
stop logging, press and hold button until LED turns
off.
NOTE: The device caches log data in volatile memory
prior to writing to memory card. When logging, always
use the button to stop logging and ensure data is written to memory
card prior to removing power.
|
| Logging Status Indication |
The LED operations when connected
to the AC Adapter power supply are different than
when connected to USB:
Logging modes:
1. Logging Off mode: the LED is off (disabled).
2. Start Logging on Power Up mode: the LED is on,
with a momentary off flash every time data is captured.
3. Start Logging on Button mode: the LED is initially
off. When the button is pressed and held for approximately
1 second the LED will turn on and act the same as
Start Logging on Power Up mode.
4. Start Logging at Specified Time mode: the LED
is off, with a momentary on flash every second until
the specified date/time is reached. At that time,
the LED will turn on and act the same as Start Logging
on Power Up mode.
Other indication:
To Stop logging and store the remaining data to memorycard, press and hold the button until the LED turns off. It is then safe to remove the memory card.
If the memory card becomes full the LED will blink rapidly (250 ms period).
If the memory card is removed while logging is in progress the LED will blink rapidly (250 ms period). Inserting a memory card will stop the blinking.
