DaqBook/100, /112, /120, /200, and /216
In General
DaqBooks consist of boards enclosed in a 8.5 × 11 × 1.375 inch metal chassis; with exception of the
DaqBook/260, which is 11 × 13 × 3.5 inches. DaqBooks attach to a host PC’s parallel port via a 25-wire
parallel port cable and can transfer data bi-directionally at up to 170 Kbytes/s for a standard printer port
(SPP) and up to 800 Kbytes/s for an enhanced parallel port (EPP). Data is stored in the PC’s memory and
hard drive, not in the DaqBook.
DaqBooks can be powered from a suitable AC-to-DC power adapter, a 12 V car battery, or a rechargeable
NICAD battery module. This power flexibility is ideal for portable and remote data acquisition, such as
automotive and aviation in-vehicle testing.
Output power from the DaqBook’s P1 connector includes: +5 VDC via pin 1, +15 VDC via pin 21, and
-15 VDC via pin 2.
Reference Notes:
The section, External Analog Expansion Power (JP1), explains how to set JP1, based on
power use in the system.
DaqBooks have capabilities which, at one time, could only be met by using several plug-in DAS boards.
All DaqBooks provide 16 analog inputs, and can be expanded up to 256. In addition, each model has 2
analog outputs, and at least 4 digital I/O channels. Some models have built-in expansion slots; other
models have additional digital I/O and counter/timer capabilities.
DaqBook Differences
While all DaqBook models are closely related, the following should be noted.
• DaqBook/112 and DaqBook/216 provide 1 slot for an expansion DBK card.
• DaqBook/100, DaqBook/120, and DaqBook/200 do not have an expansion slot, but do have
24 general-purpose digital I/O channels (expandable up to 192), 16 high-speed digital inputs,
and 5 frequency/pulse I/O channels.
• DaqBook models /120, /200, and /260 have EPP (Enhanced Parallel Port) capability.
• DaqBook/260 has 3 expansion slots for DBK cards.
• DaqBook/100, DaqBook/112, and DaqBook/120 are 12-bit.
• DaqBook/200, DaqBook/216, and DaqBook/260 are 16-bit.
