  • Page 10 UDAS SYSCHECK The SYSCHECK application enables you to verify the UDAS installation is functioning properly. SYSCHECK can also be used during the calibration procedure and for simple data acquisition. U-Link Software Libraries for Windows 98 These function libraries allow custom application development using C/C++ and Visual Basic. LabView 5.0 Support Library Allows the use of UDAS with LabVIEW.

  • Page 11: Udas 1001E Series Functional Description

    UDAS-1001E Series Data Acquisition Systems Digital Input/Output Digital Input/Output • 16 Programmable digital I/O channels. Groups of 8 separately programmable for input or output. • Digital inputs can be programmed to read digital signal status, detect a change-of-state or to perform low speed event counting (up to 2 kHz).
  • Page 12 • Programmable gains are 1, 10, and 100 which translate to a full-scale input of 0-10 V, 0-1.0 V, 0-0.1 V, 10 V, 1.0 V, 0.1 V, 5 V, 0.5 V, and 0.05 V. ± ± ± ± ± ± •...
  • Page 13 UDAS-1001E Series Data Acquisition Systems If an analog input is used for the trigger, specify the trigger level, analog input channel, and slope. Use analog output channel 1 for setting the trigger level. Note: When using analog input channel 1 for a trigger, do not use this channel for any other purpose.
  • Page 14 The scanner operates with the built-in analog channels, or with the optional AI-MAX. The AI- MAX allows up to 256 analog input channels to be connected to a single UDAS device. Note: The scanner begins on the selected trigger channel and not channel 0 when the start on trigger mode is used with an analog input trigger.

  • Page 15: Analog Output

    UDAS-1001E Series Data Acquisition Systems Example: If 9 channels are being scanned at a rate of 100Hz and the slope is low to high, the trigger signal must remain below the trigger level for 9/100 of a second, and above the trigger level for 9/100 of a second to ensure that a trigger event occurs.
  • Page 16 Digital I/O signals are TTL-compatible and perform functions such as reading digital inputs, driving digital outputs, and detecting input change-of-state. Digital I/O direction is programmable separately for each port through software. A nine-position DIP switch is provided inside of the unit to select the power-up direction of Digital I/O Port 1 (input/output) and to individually set power-up output states for each bit.
