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). • Digital outputs can drive TTL level signals. • 8 of the 16 I/O channels can be configured for preset direction and output state levels for safe power-up and reset situa

• 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. • The analog input section has 16 single-ended or 8-differential analog input channels. The analog input section has a first-in-first-out (FIFO) buffer for high-speed capturing of data up to 100 kHz. An analog trigger is also provided to initiate high-speed conversions based on a voltage transition on a selected analog input channel, or

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. When an input signal on the selected channel of the proper slope (rising or falling voltage) crosses the trigger level, the conversion process begins. Stopping Conversions To stop a convers

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. High-Speed Analog Input Triggering High-Speed Analog Input Triggering To start or stop conversions, use triggering in the High-Speed Analog Input mode in the UDAS device. The tr

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. When using External Input as the trigger, this restriction does not apply. When using an analog input channel for triggering, analog output channel 1 is used to set the trigger level. Note: Do not

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. Counters Counters One counter input line is connected to a 32-bit counte

1.2.2 1.2.2 Power Power The UDAS unit normally uses power from the host computer via the USB cable. Power can also be obtained from an external power supply that is available (See Appendix B, Accessories). When the UDAS unit is connected to a power source, the computer controls the power. The unit does not have a power switch. There is an LED labeled PWR located on the front panel that indicates power to the unit, regardless of its source. The USB specification imposes strict requirements on
