description

The DM0101 counter/timer module converts a PC into a high
performance pulse counting instrument. The module has a 32
bit count capability and includes a microcontroller and RS232
interface to communicate with a host computer. Software
supplied with the module makes the DM0101 perform a
sequence of count rate measurements as programmed by the
user. The DM0101 is supplied with software allowing
measurements to be made immediately following switch-on.
An ActiveX control driver is also provided to allow users to
develop their own control software using LabView, Visual
Basic etc. A serial lead and power and user interface connectors are included.
