The Datastick® DAS-1254 and DAS-1294 data acquisition modules bring a high level of reliability, convenience, and versatility to handheld instrumentation for test and measurement.
The DAS-1254 module has four single-ended analog inputs and the DAS-1294 has eight single-ended analog inputs. Each model provides one 16-bit digital counter, one TTL-level digital-switch input line, and two TTL-level digital-switch output lines.
Each module firmly attaches to any Palm™ Tungsten™ T, T2, T3, or C or Garmin iQue 3200 or iQue 3600 handheld. High-impedance inputs ensure compatibility with almost any active analog sensor. The new, integrated 20-pin connector features a harpoon latch for a more secure connection and is shielded for lower noise than the original DAS-1245.
Both models are powered by a pair of on-board AAA alkaline batteries or by an optional external power supply (see Accessories). Power management has been redesigned from the ground up to provide improved power consumption over the original DAS-1245.
The DAS-1254 and DAS-1294 include Datastick Connection Lite software for basic functionality right out of the box. Other software applications — Datastick Connection and Datastick Connection Plus — are sold separately and provide better performance, specialized features, and greater convenience.
The DAS-1254 and DAS-1294 data acquisition systems, hardware and software, are ideal for applications as varied as R&D, lab work, field testing, quality assurance, industrial control, environmental studies, and education, and they fit almost any budget.
