Chapter 3 3 Signal Connections This chapter provides useful informa-tion about how to connect input and output signals to the PCIE-1810 card via the I/O connector.
3.1 Overview Maintaining signal connections is one of the most important factors in ensuring that your application system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. This chapter provides useful information about how to connect input and output signals to the PCIE-1810 card via the I/O connector. 3.2 Switch and Jumper Settings Please refer to Figure 3.1 for jumper and switch locations on PCIE-1810.
The PCIE-1810 has a built-in DIP switch (SW1), which is used to define each card’s board ID. When there are multiple cards on the same chassis, this board ID switch is useful for identifying each card’s device number. After setting each PCIE-1810, you can identify each card in system with different device numbers. The default value of board ID is 0 and if you need to adjust it to other value, please set the SW1 by referring to Table 3.1.

Appendix B B Operation Theory
B.1 Analog Input Operation This section describes the following features of analog input operation theory that can help you realize how to configure the functions and parameters to match various applications. A/D Hardware Structure Analog input ranges and gains Analog data acquisition mechanism Analog input acquisition modes A/D SCAN/CONV clock source A/D trigger sources Analog input data format B.1.
The PCIE-1810 can measure both unipolar and bipolar analog input signals. A unipolar signal can range from 0 to 10 V FSR (Full Scale Range), while a bipolar signal extends within ±10 V FSR. The PCIE-1810 provides various programmable gain levels and each channel is allowed to set its own input range individually. Table B.1 lists the effective ranges supported by the PCIE-1810 with gains. Table B.1: Gains and Analog Input Range Gain Unipolar Analog Input Range Bipolar Analog Input Range 0.
Double-Clock Procedure Double clock procedure is the fundamental A/D conversion mechanism of the PCIE1810, regardless of which mode selected. The incoming SCAN CLK launches an acquisition period called Acquisition Window. The arriving CONV CLKs within the Acquisition Window will become an efficient A/D conversion clock to trigger A/D converter. The number of efficient CONV CLK depends on the number of active scanning (multiplex) channels and software-programed iteration counters.

B.1.4 A/D Trigger Modes The PCIE-1810 supports four trigger modes and pause function. User can start or stop the operation by trigger mode selection. An extra 32-bit counter is dedicated to delay-trigger mode and about-trigger mode, and user can set it as the number of delay SCAN CLKs before trigger or the number of holding SCAN CLKs after trigger. Figure shows the four different trigger modes.
Start Trigger Acquisition Mode Start trigger acquisition starts when the PCIE-1810 detects the trigger event and stops when you stop the operation. The SCAN CLKs before Trigger will be blocked out. You can set post-trigger acquisition mode by software. Delay to Start Trigger Acquisition Mode In delay to start trigger mode, data acquisition will be activated after a preset delay number of SCAN CLKs has been taken after the trigger event. User can set the delay number of SCAN CLKs by a 32-bit counter.
Stop Trigger Acquisition Mode Stop trigger mode is a particular application of about-trigger mode. Use pre-trigger acquisition mode when you want to acquire data before a specific trigger event occurs. Stop-trigger acquisition starts when you start the operation and stops when the trigger event happens.
B.1.5 A/D SCAN/CONV Clock Source The PCIE-1810 can adopt both internal and external clock sources to accomplish pacer acquisition. You can set the clock and trigger sources conveniently by software. The figure can help you understand the routing route of clock and trigger generation.
B.1.6 A/D Trigger Source The PCIE-1810 supports the following trigger sources for start, delay to start, delay to stop, stop trigger acquisition modes: External digital (TTL) trigger Analog threshold trigger With PCIE-1810, user can also define the type of trigger source as rising-edge or falling-edge. These following sections describe these trigger sources in more detail.
Analog Threshold Trigger For analog input operations, an analog trigger event occurs when the PCIE-1810 detects a transition from above a threshold level to below a threshold level (falling edge), or a transition from below a threshold level to above a threshold level (rising edge). User should connect ana-log signals from external device or analog output channel on board to external input signal ATRG0/1. On the PCIE-1810, the threshold level is set using a dedicated 12-bit DAC.
Single Value Operation Mode The single value conversion mode is the simplest way for analog output operation. Users can set the mode of each channel individually. Then users just need to use software to write output data to specific register. The analog output channels will output the corresponding voltage immediately. In the single value operation mode, users need not set any clock source and trigger source, but only output voltage range.
B.2.3 D/A Clock Sources The PCIE-1810 can adopt both internal and external clock sources for pacing the analog output of each channel: Internal D/A output clock with 32-bit Divider External D/A output clock from connector The internal and external D/A output clocks are described in more detail as follows: Internal D/A Output Clock The internal D/A output clock applies a 100 MHz time base divided by a 32-bit counter. Conversions start on the rising edges of counter output.
The PCIE-1810 supports 24 digital I/O channels. You can use each byte as either an input port or an output port by configuring the corresponding parameter; and all four channels of the byte have the same configuration. You do not need to specify the clock source or trigger source. To output the data, you just need to write it to the digital output channel directly. In the same way, you can directly read back data from digital input channel.
3. Pulse Width measurement: PCIE-1810 built-in counter can measure the pulse width value of the signal connected to counter input. The measurable range is 50 ns to 107 seconds. You can measure both the logic high time and logic low time within the measurable range. 4. Pulse Output with Timer Interrupt: PCIE-1810 counter has internal clock that you can produce periodic output signal with interrupt generated at the same time.
Delay Pulse Generation: Using PCIE-1810 internal clock, you can change the logic level within a specific period, starting from a trigger signal connecting to counter gate input. For example, if you define the count equals to 3 (as figure below), a counter output will change its status after 3 pulses of internal clock signals pass, after a trigger signal from counter gate becomes high. 6.
