The status of the interface module is shown electronically with the output («ERR
NOT»). ERR NOT is a 5-volt output (TTL level), where a «low - signal» = «pending
error» and a «high - signal» = «no error».
6.2.5. Using the analog interface module with the USB counter 026 or 046
(for technical information, see chapter 12 in the MINI-X product
catalogue).
The USB counters mentioned above allow MINISCALE PLUS to be connected
directly to a computer via USB.
Current consumption:
< 150 mA
Storage temperature of the USB counter:
-30 °C to + 70 °C
Operating temperature of the USB counter:
0° to 45 °C in relative humidity of <75%.
When using the USB counter’s analog input, the interpolator built into the USB
counter reaches a resolution of just 256 (= 28). As a result, the resolution displaya-
ble with the USB counter is limited to 0.39 µm. A speed of 5 m/s is guaranteed,
and the maximum input frequency amounts to 75 kHz (based on one channel, e.g.
the A signal.)
The maximum length for the USB cable is 5 meters. With a USB repeater cable,
the USB connection can be extended up to a maximum of 25 m.
• For operating the USB counter, PC software for demonstrating the functionality
is available.
• A DLL file is available for customers that wish to write their own software
applications.
