Summary of DaqBook/2001 and DaqOEM/2001 Channels
DaqBook/2001 is a high-speed, multi-function, data acquisition module. DaqOEM/2001 is a board with
the same functionality, but no chassis. Both devices feature a 16-bit, 200-kHz A/D converter, digital
calibration, four 16-bit, 100-kHz D/A converters, 40 digital I/O lines, four counters, and two timers. Both
connect to a PC or Ethernet network via a 10/100BaseT Ethernet port.
Up to 470 channels of analog and digital I/O can be accessed with one DaqBook/2001 or one
DaqOEM/2001 board. Up to 896 thermocouple channels can be accessed with the use of DBK90 and
DBK100 expansion modules.
P1, P2, and P3 37-pin connectors provide access to all I/O signals. Port descriptions follow:
• P1 – Analog input port for16 single-ended or 8 differential analog inputs with 13 software
programmable ranges (±10 V to ±156 mV full scale).
• P2 – General purpose digital I/O port with 24 lines, or digital I/O expansion port controlling
up to 192 external lines.
• P3 – 16-bit digital I/O port, counter inputs, timer outputs, and analog outputs.
The on-board scan sequencer lets you select up to 16384 channel/range combinations. The sequencer scans
all channels of the scan at 5µs/channel, 10µs/channel, or 1000µs/channel.
100M-bit Ethernet allows analog and digital/counter input data, as well as analog and digital output data, to
flow between the PC and the DaqBook/2001, or to the DaqOEM/2001.
DaqBook/2001 and DaqOEM/2001 each support a full complement of trigger modes including:
• Hardware analog triggering – A user-programmed trigger level sets an analog DAC, which is
compared in hardware to the analog input level on the selected channel. Trigger latency is < 5 µs.
• Digital and pattern triggering – Each device has a separate digital trigger input line, allowing
TTL-level triggering and latencies less than 5 µs. The trigger can be programmed for logic level
or edge triggering. In pattern triggering, any of the digital input ports acts as the trigger port. You
can program the digital pattern.
• Software-based triggering – The PC detects the trigger event from analog, digital, or counter
readings. Six pre- and post-triggering modes are supported. Trigger latency is one scan period.
The four 16-bit, 100-kHz analog output channels have an output from -10 V to +10 V.
Other features of the DaqBook/2001 and DaqOEM/2001 include:
• 40 TTL-level digital I/O lines. They are divided into three 8-bit ports and one 16-bit port.
• Four 16-bit counters. Each can accept frequency inputs up to 10 MHz. The counters can be
cascaded into two 32-bit counters.
• Two 16-bit timer outputs. Each can generate square waves from 16 Hz to 1 MHz.
• Configuration through software. There are no switches or jumpers on the DaqBook/2001 or on
the DaqOEM/2001.
