UMDAS 0802HR
The CyberResearch brand UMDAS 0802HR supports the following UDR Library and UDR Library for .NET
features.
Analog input
Analog input functions and methods supported
UDR:
cbAIn(), cbAInScan(), cbALoadQueue()*, cbFileAInScan(), cbATrig()
UDR for .NET:
AIn(), AInScan(), ALoadQueue()*, FileAInScan(), ATrig()
*The channel-gain queue is limited to eight elements. The UMDAS 0802HR
accepts only unique contiguous channels in each element, but the gains may be any
valid value.
Analog input argument values
Options BACKGROUND, BLOCKIO**, BURSTIO***, CONTINUOUS, EXTTRIGGER, CONVERTDATA,
NOCALIBRATEDATA, SINGLEIO**, and EXTCLOCK.

SINGLEIO
Equals the number of channels being sampled.
*** BURSTIO can only be used with the number of samples (Count) set equal to the
size of the FIFO or less. The UMDAS 0802HR’s FIFO holds 32,768 samples. Also,
BURSTIO cannot be used with the CONTINUOUS option.
HighChan 0 to 7 in single-ended mode
Count In BURSTIO mode, Count needs to be an integer multiple of the number of
channels in the scan.
▪ For three- and six-channel scans, the maximum
Count is 32766 samples
▪ For five-channel scans, the maximum
Count is 32765 samples
▪ For seven-channel scans, the maximum
Count is 32767 samples
▪ For one-, two- , four-, and eight-channel scans, the maximum
Count is 32768
samples.
Rate 200 kHz maximum for BURSTIO mode (50 kHz for any one channel). The
maximum rate is 100 kHz for all other modes (50 kHz for any one channel). When
using
cbAInScan() or AInScan(), the minimum sample rate is 1 Hz. In BURSTIO
mode, the minimum sample rate is 20 Hz/channel.
Range Single-ended mode:
BIP10VOLTS (± 10 V) BIP2VOLTS (± 2 V)
BIP5VOLTS (± 5 V) BIP1VOLT (± 1 V)
