Page 15: Connecting Signals
DEWE-ORION-1616-10x 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 47. 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. -

Example for input range ±5 V Ch x = +8 V, Sense = 4 V, voltage difference = 4 V, result is valid Ch x = +10 V, Sense = 6 V, voltage difference = 4 V, result is not valid (the input voltage is less than 12 V but the sense voltage level (6 V) is higher than the input range. -

All the baseboard functionality stays the same like in the standard configuration. Similar to the counter inputs of DEWE-ORION-1616-100/101, 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 31: Clock And Trigger I/O
DEWE-ORION-1616-10x 2.6 Clock and trigger I/O The DEWE-ORION-1616-10x 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. EXT_CLKx are used as standard for hardware synchronization to DEWE-CAM, CAN or 3 party hardware. Each output can set individually. The predefined settings are: Video: The output frequency is automatically set to the frame rate of the selected video device. If no camera is selected, the output is disabled CAN: The signal is automatically set for hardware synchronisation of NI-CAN device. - Page 32 DEWE-ORION-1616-10x The output of all slave board is switched off. The diagram below gives an idea of the internal structure of EXT_CLKx and EXT_Trigger circuit: EXT_CLKx internal signal: ADC sample clock or 80 MHz DIR_CLK EXT_Trigger internal signal: start of acquisition DIR_Trigger EXT_CLK1 internal signal: CLK1 I/O DIR_CLK1 EXT_CLK2 internal signal: 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 33: Can Interface
2.8 RS-485 interface The DEWE-ORION-1616-10x 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-1616-102 with counter ex- pansion) is controlled separately. -

3.1.4 Calibration Your DEWE-ORION-1616-10x is shipped with a calibration certificate. Typically a recalibration is required every year. The calibration constants are stored in the on-board EEPROM. The calibration can only be done with an optional available calibration kit or you can send the DEWE-ORION-1616-10x back to DEWETRON for recalibration.

Page 39: Gated Event Counting
DEWE-ORION-1616-10x 3.2.1.2 Gated Event Counting Gated Event Counting is similar to Event Counting except that the counting process is gated. When Counter Gate is active, the counter counts pulses which occur on counter source. When Counter Gate is inactive the counter retains the current count value. -

Page 41: Period Time Measurement
DEWE-ORION-1616-10x 3.2.1.4 Period Time Measurement In Period Time Measurement the counter uses the internal time base to measure the period time of the signal present on Counter Source. The counter counts the rising edges of the internal time base which occurs between two rising edges on Counter Source. -

Page 44: Quadrature Encoder
DEWE-ORION-1616-10x 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 45 DEWE-ORION-1616-10x 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.

DEWE-ORION-1616-10x 3.2.1.9 A-Up/B-Down Encoder The A-Up/B-Down Encoder supports two inputs, A and B. A pulse on Input A increments the counter on its rising edges. A pulse on Input B decrements the counter on its rising edges. At every Sample Clock ( …, ) the counter value is read out. -
Page 47: Frequency Measurement
DEWE-ORION-1616-10x 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. -

If the gate time is set to “Off”, no filter is on the input signal. -

DEWE-ORION-1616-10x 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 50: Count Direction
DEWE-ORION-1616-10x 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-1616-10x 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 separation measurement) there may be new information between two samples. -
