Page 15: Connecting Signals
DEWE-ORION-0824-20x 2.3 Connecting signals 2.3.1 Naming In multiple board systems a clear defined channel name structure is important to avoid inconstancy in the channel connection. Usually analog input channels are just named in a row. Therefore at a 3 board system the channels are named from CH 0 to CH 23. Due to the flexible structure of the digital and counter inputs the naming in a row is not possible. That’s why each input at the ORION base board (code letter B) and also at the expansion board (code letter E) gets a channel prefix name like shown in the example below for a two board system. -

DEWE-ORION-0824-20x 2.5 Counter and digital I/O 2.5.1 General functionality The DEWE-ORION-0824-20x is also suited with synchronous 32-bit advanced 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 counter 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 26 DEWE-ORION-0824-20x Main Counter Start / stop trigger ARMED Selected source input SOURCE Main Counter Value Selected gate input GATE Selected aux input AUX (UP / DOWN) Sub Counter Selected source input SOURCE Sub Counter Value Figure 3: Counter functions The sub counter is automatically switched on in the background if the measurement result needs principal two counters.

DEWE-ORION-0824-20x 2.5.3 Counter and DI/O DEWE-ORION-0824-200/201 The counters and digital input and output at the DEWE-ORION-0824-200 can be configured in the most flexible way. The DEWE-ORION-0824-200/201 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. DI0 to DI7 can be used as digital input and / or for the coun- ter inputs. - Page 28 DEWE-ORION-0824-20x The levels can be set for each input independent like shown on this page. Some common used levels are predefined (like TTL, inductive pick-up sensors…). Selecting “Custom” as the trigger type. All parameters are free definable. If the sensor signal is not known, an automatic algorithm for finding the trigger levels is implemented. A sensor like the shown encoder has usually for all outputs the same signal level. Enabling “trigger settings same for all lines”...

DEWE-ORION-0824-20x 2.5.4 Counter and DI/O DEWE-ORION-0824-202/203 The number of counters and digital inputs can be expanded with the counter expansion add-on board. All the baseboard functionality stays the same like in the standard configuration. Similar to the counter inputs of DEWE-ORION-0824-200/201, the input pins can also share the function for digital inputs or counter inputs. Please also refer to the pin-out description in chapter 2.3.1. The block diagram (figure 6) indicates that eight counter channels and theoretically 16 digital inputs can be transferred at once. -

Page 33: Rs-485 Interface
2.8 RS-485 interface The DEWE-ORION-0824-20x is suited with an RS-485 interfaced as standard. The baud-rate is fixed to 9600, 8 Data, 1 Stop bit and no parity. This interface is used for configuration of the DAQ and MDAQ signal conditioning modules. Also the acquiring of PAD and EPAD from DEWETRON is possible with this RS-485 port. The interface of the main board and the expansion boards (DEWE-ORION-0824-202 with counter ex- pansion) is controlled separately. -

Page 38: Analog To Digital Conversion
DEWE-ORION-0824-20x Amplifier setup in DEWESoft 3.1.3 Analog to digital conversion The DEWE-ORION-0824-20x uses 8 delta-sigma A/D converters. If you sample with a data rate of 102.4 kS/s, the ADC actually samples the input signal with 13.1072 MS/s (multiply the data rate with 128) and produces 1-bit samples which are applied to the digital filter. The filter expands the data to 24-bits and rejects signal parts greater than 51.2 kHz (Nyquist frequency). - Page 39 DEWE-ORION-0824-20x When the sampler modulates frequencies out of the Nyquist bandwidth back to the 0 to 500 Hz baseband it is called aliasing. Signals which are not pure sine wave can have many components (harmonics) above the Nyquist frequency. These harmonics are erroneously aliased back to the baseband, added to parts of the accurately sampled signal and produces a distorted data set.

Page 41: Output Data Format
DEWE-ORION-0824-20x To set nearly each frequency a low jitter programmable PLL (phase locked loop) circuit is used for generating the clocking frequency. PLL gives the best solution for variable frequency setting with small steps between the frequency. But still not every frequency is possible to set. The formula below gives you an idea how the frequency can be set to get different sample rates: 12.8 MHz . -

Page 49: Quadrature Encoder
DEWE-ORION-0824-20x 3.2.1.8 Quadrature Encoder In the first case X1 decoding is explained. When Input A leads Input B in a quadrature cycle, the counter increments on rising edges of Input A. When Input B leads Input A in a quadrature cycle, the counter decre- ments on the falling edges of Input A. At every Sample Clock ( , …, ) the counter value is read out. - Page 50 DEWE-ORION-0824-20x Figure 20 shows the results for X4 encoding. Sample Clock Input A Input B Counter Value 3 4 5 6 7 8 17 16 Synchronized Value Figure 20: Quadrature Encoder X4 Mode The third channel Input Z, which is also referred as the index channel, causes the counter to be reloaded with zero in a specific phase of the quadrature cycle.

Page 52: Frequency Measurement
DEWE-ORION-0824-20x 3.2.1.10 Frequency Measurement In general it is possible to take the inverse of a period measurement to get the frequency of the input signal. If the period time measurement is done an inaccuracy of counted internal time base cycles of ±1 cycle ap- pears, because the counted cycles of the internal time base depends on the phase of the input signal with re- spect to the internal time base. -

DEWE-ORION-0824-20x 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. -
Page 55: Count Direction
DEWE-ORION-0824-20x 3.2.2.3 Count Direction As default setting the count direction is in up-counting mode. Every rising edge at the input will increase the counter value. The DEWE-ORION-0824-20x supports also down counting without the need of an additional input like in the up/down counting mode. 3.2.2.4 No new value available Especially in every kind of input period time measurement mode (also pulse width or two pulse edge separa- tion measurement) there may be new information between two samples. -
