Page 20: Counter And Digital I/O
2.5 Counter and digital I/O 2.5.1 General functionality The DEWE-ORION-0816-5M/10M is also suited with synchronous 32-bit counters and digital inputs. The flexible signal routing allows easy signal connection and the usage of the same input pin for all counter input func tions and for digital inputs. Some pins also can be used for digital output. In addition to the basic coun- ter function like simple event counting, up/down counting and gated event count ing also period time, pulse width, two-edge separation, frequency and all encoder measurements are sup ported. - Page 21 DEWE-ORION-0816-5M/10M series The counters at DEWE-ORION-0816-5M/10M cards are organized in pairs. The pins of each pair can be routed to the counter block of the pair counter. This gives the possibility to measure with just one input the frequency AND also counting the pulses. Also additional pins can be routed to the counter blocks. For example the ADC-clock can be used to measure the period time if the board is used in the external clocking mode.

2.5.3 Counter and DI/O DEWE-ORION-0816-5M/10M The counters and digital input and output at the DEWE-ORION-0816-5M/10M can be configured in the most flexible way. The DEWE-ORION-0816-5M/10M provides high voltage differential inputs protected up to 100 Vpeak with a common minus input (for example In- Bx_CNT0) for each counter. Furthermore a programmable trigger and re-trigger level of each input, from 0 to 40 Volt and a software selectable AC/DC coupling with 1 Hz cut off frequency, is included. - Page 23 EXT_CLK2 EXT_CLK2 EXT_CLK2 The upper 8 bits of the digital input word also can be configured to output. Writing the outputs is an asyn- chronous action defined by the host application software. But even when if the output mode is activated the output level also can be measured to get the exact timing information when the output is really set.

Page 24: Clock And Trigger I/O
The output settings can be done inside the hardware setup of DEWESoft. 2.6 Clock and trigger I/O The DEWE-ORION-0816-5M/10M allows external triggering for start of the acquisition using the pin EXT_ Trigger. The default detection for the trigger signal is the rising edge but can be configured to falling or both edge (change of input signal) detection. Changing the direction to output, the start of acquisition can be indicated. - Page 25 EXT_CLK2 CLK2 I/O DIR_CLK2 Figure 7: Clock and trigger I/O configuration The direction (input or output) of each pin can be switched separately.

Page 26: Can Interface
DEWE-ORION-0816-5M/10M series 2.7 CAN interface As an option the DEWE-ORION-0816-5M/10M also can be suited with two high speed CAN interfaces. Both ports are compatible with CAN 2.0B specification. The CAN transceiver (TI SN65HVD235) has a bus-pin fault protection of up to ±36 V. The main application for these CAN-ports is acquiring CAN data together with analog data. Although the CAN data is asynchronous to the analog data, the DEWE-ORION-0816-5M/10M series guarantees perfect synchronization. -

Page 30: Theory Of Operation
3 Theory of operation 3.1 Data rate The DEWE-ORION-0816-5M/10M can produce a very high amount of data. Due to PCI bus limitation it is not always possible running the cards at full speed. The limiting factors are the PCI-bus and the hard disk. The hard disk could be easily accelerated by using SSD’s and/or Raid configuration. The PCI bus speed is given by the system. Be aware that in standard systems all PCI... -

Page 32: Calibration
3.2.4 Calibration Your DEWE-ORION-0816-5M/10M is shipped with a calibration certificate. Typically a recalibration is re- quired every year.

DE-M131001E • DEWE-ORION-0816-5M/10M • Technical Reference Manual • Printing version 1.0.2 • April 07, 2015 Page 43... - Page 44 DEWE-ORION-0816-5M/10M series Internal Time Base (80MHz) Filter Input Signal Filter Output Signal Gate Time Gate Time Figure 25: Input signal with chatter It can be chosen between eight filter settings: Off, 100 ns, 200 ns, 500 ns, 1 µs, 2 µs, 4 µs and 5 µs. Two examples of filter settings are described. The 100 ns filter will pass all pulse widths (high and low) that are 100 ns or longer. It will block all pulse widths that are 75 ns or shorter. The 5 µs filter will pass all pulse widths (high and low) that are 5 µs or longer and will block all pulse widths that are 4.975 µs or shorter. The internal sampling clock (time base) is 80 MHz, so the period time amounts 12.5 ns. Pulse widths be- tween gate time minus two internal time base period times may or may not pass, depending on the phase of the input signal with respect to the internal time base.
