| Description The VSA™-2215
hardware module attaches firmly to Palm® Treo™ 650, 700p, or 755
smartphone to form compact, extremely portable instrument. The
Palm Treo supplies the computing power, 60 MB of data storage,
and mobile telephone, email, and text-message capability, while
the Datastick® VSA hardare module supplies the sensor power and
interface. SD (Secure Digital) memory cards — up to 2 GB each —
provide virtually unlimited auxiliary storage.
The VSA hardware modules each have a standard BNC connector
and a very low-noise input that accommodates and powers almost
any ICP®-type piezoelectric accelerometer or velocity sensor.
Power
The VSA modules have internal rechargeable Li-Ion batteries
and advanced power management capabilities that typically
stretch the VSA-2215 to four hours between recharges on an
average duty cycle (you can recharge on your lunch break) and
the VSA-2215 can go a full shift or longer.
An optional 4800 mA/h rechargeable external bettery pack is
available if you need more power, and it gives you the added
benefit of powering or recharging BOTH the VSA module and the
Palm Treo smartphone.
