1 Introduction

1.1 Introduction of PC/104-plus

PC/104-plus is a special bus architecture designed for embedded systems. A third connector opposite the PC/104 connectors supports the PCI bus. Basically the electrical specifications of the PC/104-plus bus are compliant with the PCI signals, except 64-bit extensions, JTAG, PRSNT or CLKRUN signals. The mechanical specifications are changed to “module stack”; please refer to the figure shown below. According to the specifications of PC/104-plus, PC/104-plus modules are installed and configured by switching CLK, IDSEL, INT, REQ and GNT signals through multiplexers to the appropriate connections.

Rotary switch on PCM-9112+ is used for these signals switching, please refer to section 2.4 for details in this appendix.

1.2 Specifications for PCM-9112+

The specifications of the PCM-9112+ are the same as that of the PCI-9112 except for the Digital Input and Digital Output functions have been removed from the PCM-9112+. To compensate for the removal of the DI/DO functions, the AD FIFO has been enlarged to 512 words allowing it to handle a wider range of applications. Please refer to section 1.3 of the PCI-9112 manual for further details.

1.3 Supported Software

PC/104+ Host

The supported software is the same as that of the PCI-9112 without the DI/DO functions. Please refer to section 1.4 of the PCI-9112 manual for further details.

2 Installation procedures for PC/104-plus DAQ modules:

2.1 what you have

In addition to this appendix, the package includes the following items:

 PCM-9112+ DAQ modules

 Manual & Software Utility CD-ROM

If any of these items is missing or damaged, contact the dealer from whom you purchased the product. Save the shipping materials and carton in case you want to ship or store the product in the future.

2.2 unpacking

The card contains electro-static sensitive components that can be easily be damaged by static electricity.

Therefore, the card should be handled on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat.

2.4 PC/104-plus configuration

A rotary switch on the PCM-9112+ is used for switching the appropriate CLK, IDSEL, INT, REQ and GNT signals from the PCI bus. If the PCM-9112+ card is inserted in a position nearest to the PC/104-plus motherboard, the switch must be set to 0 or 4. For signal stability, the rotary switch should be set to the appropriate position with respect to the module slot. The module stack order was shown in Figure 1. According to PC/104-plus specification, module slots 3 and 4 share REQ2/GNT2, hence they cannot both have bus-mastering devices. In another word, module 3 and 4 cannot be stacked with 2 PCM-9112+ modules.

2.5.1 Analog input mode configuration

The analog input channels on the PCM-9112+ DAQ module can be configured as 16 single-ended or 8 differential inputs. Jumpers JP1 and JP4 control the analog input configuration. The setting of JP1 and JP4 are specified below:

2.5.2 Clock Source Setting

The programmable 8254-interval timer is used in the PCM-9112+. It provides 3 independent 16-bit programmable down counters. Input of counter 2 is connected to an accurate 2MHz oscillator used as the internal pacer. Input of counter 1 is cascaded from the output of counter 2. Channel 0 is free for user applications. There are two selections for the clock source of channel 0: the internal 2MHz clock or an external clock signal. The setting for clock signal is shown in the following table.

2.5.3 D/A Reference Voltage External/Internal Setting

The D/A converter’s reference voltage source can be supplied either by internal or external sources. For external reference voltage, pin 3 (ExtRef1) and 4 (ExtRef2) of connector CN2 are used. Reference voltage source for D/A of channel 1 and 2 are selected by JP4. Possible settings are shown below:

D/A Reference Voltage Setting

D/A CH1 is external D/A CH2 is external

D/A CH1 is external D/A CH2 is internal

D/A CH1 is internal D/A CH2 is external

D/A CH1 is internal D/A CH2 is internal

Table 5: D/A reference voltage setting

2.5.4 Internal Reference Voltage Setting

The internal reference voltage can be set to either –5V or –10V by JP3. Possible configurations are illustrated in the table below. Note that the internal reference voltage is used only when JP5 is set to internal reference only. If –10V internal reference voltage is selected, the D/A output range is 0V~10V. On the other hand, if the –5V is selected, the D/A output range is 0V~5V.

2.7 Daughter Boards and Accessories

The PCM-9112+ DAQ module has several available accessories allowing for easy signal wiring for measurements and control. Functionality and connections of the available accessories are describe in the in the following sections.

2.7.1 Connect with ACLD-9137

Equipped with a 37-pin D-sub connector, the ACLD-9137 provides a simple way for connection. Intuitively layout and reliable screw clamp terminal allows for easy wiring. In conjunction with the ACL-10337 (two 20-pin headers to DB-37 cable), users can set up the connection immediately.

Figure 6: Connect with ACLD-9137

2.7.2 Connect with DIN-37D

The DIN-37D is a termination board with a DIN socket. When users need to mount the termination board onto the DIN rail, it provides a convenient interface for installation. To achieve this connection, use the following cables ACL-10337 and ACL-10137.

Figure 7: Connect with DIN-37D

2.7.3 Connect with ACLD-8125

The ACLD-8125 has a 37-pin D-sub connector, which can connect to the PCM-9112+ through a ACL-10337 and ACL-10137 cable. The most outstanding feature of this daughter board is the CJC (cold junction compensation) circuit. You can directly connect a thermocouple onto the ACLD-8125 board. The CJC is only suitable for high gain analog input mode.

Figure 8: Connect with ACLD-8125

2.7.4 Connect with DIN-20P

The DIN-20P has a 20-pin ribbon connector with a DIN socket. This board is connected to the PCM-9112+ via a 20-pin ribbon cable.
