Safety Precautions - Static Electricity Follow these simple precautions to protect yourself from harm and the products from damage. To avoid electrical shock, always disconnect the power from the PC chassis before manual handling. Do not touch any components on the CPU card or other cards while the PC is powered on.
The iDAQ-731, iDAQ-751 and iDAQ-763D are digital I/O modules. The function for these models are isolated digital I/O, TTL I/O and solid-state relay (SSR) respec- tively.
- the system should be in idle mode. Driver Installation The driver package could be found on Advantech Support Portal (https://www.advan- tech.com/support). Search for iDAQ on the support portal, then the corresponded driver/SDK package could be found. You’ll get the XNavi installer after the download session finishes.

Installation This section provides guides from module installation to signal wiring for the iDAQ modules. Below are the steps to insert the iDAQ modules into the iDAQ chassis. Insert the module and follow the guide rail to the end. Fix the two screws tight onto the chassis. Figure 2.1 Installing iDAQ modules into the iDAQ chassis iDAQ-731_751_763D User Manual...
ON state logic level or lower than the minimum value of OFF state logic level. The device may be damaged under such circumstance. Refer to A1. Isolated Digital Input (iDAQ-731) for OFF and ON state logic level for the device.
2.2.2 Isolated Digital Output Connection A digital output channel sends a signal through a galvanic isolator to control the ON/ OFF state of a MOSFET switch. The state of the MOSFET switch then decides if the load is conducting or not. The universal digital output channel supports both sink (NPN) type and source (PNP) type connection as shown in Figure 2.3.
Page 21
For a source type digital output, the external source is connected to the digital output common (DOCOM) terminal. The current which flows through the load is sourced from the DO terminal. This is shown in Figure 2.5. Connect the negative terminal of the external source to the DOGND terminal for a correct potential reference.
2.2.3 TTL Digital Input A digital input/output (DI/O) channel can be configured by software to perform digital input measurement, which is the power-on default configuration, or digital output generation. When performing digital input measurement, the voltage logic level between the digital input (DI) terminal and the digital ground (DGND) terminal is mea- sured.
Figure 2.7 Digital input signal connection using a switch with internally pulled- down. 2.2.4 TTL Digital Output A digital input/output (DI/O) channel can be configured by software to perform digital input measurement, which is the power-on default configuration, or digital output generation.
2.2.5 Solid-state Relay (SSR) Output Connection A solid-state relay (SSR) output channel sends a signal to control the ON/OFF state of an SSR. The state of the SSR then decides if the load is conducting or not. This is shown in Figure 2.9. Figure 2.9 Solid-state relay output signal connection.

Function Details The iDAQ system rely on the chassis module as a platform to compromise all the sig- nals together, in order to achieve functions including synchronization, data streaming and timing control. This chapter describes all the functions that the iDAQ systems provide and how they work.
Digital Input Insert an iDAQ module supporting digital input function to perform digital input mea- surement. The following sections describe the digital input acquisition mechanism. For detailed specifications of the functions, refer to the document of the corre- sponded iDAQ module. 3.3.1 Digital Input Functions There are two functions, interrupt and debounce filter other than the input value read-...

3.3.1.2 Digital Input Pattern Match Interrupt Digital input channels can also generate an interrupt by detecting a specific pattern. The pattern can be configured by ports, and each channel can be enabled or dis- abled the detection independently. For example, if channels 0, 1, 2, 3, 6, and 7 of a digital input port is pattern match detect enabled, and the pattern is “10xx0100”...
3.3.2 Instant Digital Input Acquisition With instant digital input acquisition, the software controls the sample timing. Each time the software sends a “read instant digital input sample” command, the state of all digital input channels is sampled as shown in Figure 3.8. Figure 3.8 Instant digital input acquisition.
Configuration for Buffered Digital Input Acquisition According to software configurations, buffered digital input acquisition can be classi- fied into two types: One-buffered digital input acquisition Streaming digital input acquisition 3.4.1 One-buffered Digital Input Acquisition For one-buffered acquisition, only a specified number of samples is acquired. The start or stop of acquisition can be controlled by a software command or a hardware signal.
Page 35
3.4.1.2 Pre-Trigger Acquisition A pre-trigger acquisition acquires a specified number of samples before the stop trig- ger. The acquisition is started by a software command and stops when a hardware stop trigger is received. Figure 3.12 shows an example of a 5-sample pre-trigger acquisition.
3.4.2 Streaming Digital Input Acquisition For a streaming acquisition, the number of samples to be acquired is set to infinite. The acquisition starts when a start trigger is received and continues until a stop trig- ger is received as shown in Figure 3.14. Figure 3.14 Streaming acquisition.

Digital Output Insert an iDAQ module supporting digital output function to perform digital output update/generation. The following sections describe the digital output update/genera- tion mechanism. These output functions are applied to TTL digital output, isolated digital output and SSR/Mechanical relay output, i.e. all the digital output modules. For detailed specifications of the functions, refer to the document of the corresponding iDAQ module.
The start and stop of the generation are controlled by the start trigger and stop trig- ger, respectively. When configuration is completed, the acquisition engine of the iDAQ chassis is at standby state. After receiving a start trigger, generation becomes active and each rising edge of the sample clock converts one analog output sample.
Configuration for Buffered Digital Output Generation According to software configurations, buffered digital output generation can be classi- fied into two types: One-buffered digital output generation Streaming digital output generation 3.6.1 One-Buffered Digital Output Generation For one-buffered generation, only a specified number of samples is generated. The generation starts when a start trigger is received and automatically stops when the specified number of samples is generated.
3.6.2 Streaming Digital Output Generation For a streaming generation, the number of samples to be generated is set to infinite. The generation starts when a start trigger is received and continues until a stop trig- ger is received as shown in Figure 3.25. Figure 3.25 Streaming generation.
