Non-isolated high precision analog board for Low Profile PCI AD16-64(LPCI)LA * Specifications, color and design of the products are subject to change without notice. This product is a PCI bus compatible interface board with 64 high-precision, 16-bit analog channels, digital and output channels (4 channels each), and a 32-bit counter (1 channel) This product supports a Low Profile size slot and, if replaced with the supplied bracket, supports a standard size slot, too. The board can build a space-saving PC into a cost-effective analog system. Using the bundled API function library package [API-PAC(W32)], you can create Windows application software for this board in your favorite programming language supporting Win32 API functions, such as Visual Basic or Visual C++. It can also collect data easily without a program when the data logger software [C-LOGGER] stored on the attached CD-ROM is With plug-ins for the dedicated libraries, the board also supports MATLAB and LabVIEW. Features Multi channel analog Capable of analog of 64 single-ended channels or 32 differential channels. The selection of the single-ended and the difference can be set with software. Rich set of basic functions Compact system providing high-precision analog s. Equipped with analog s, analog control signals (TTL level, 3ch), digital s (TTL level, 4ch), digital outputs (TTL level, 4ch), and counter (TTL level 32-bit, 1ch) Substantial control functions Capable of analog either time-based mode or external-signal synchronous mode. Filter function facilitating external signal connection The external control signals for analog incorporate a digital filter to prevent problems such as chattering. Software-based calibration function Calibration of analog can be all performed by software. Apart from the adjustment information prepared before shipment, additional adjustment information can be stored according to the use environment. Exchangeable Low Profile size and standard size slots Support for both of Low Profile size and standard size slots (interchangeable with a bundled bracket). Supported to the data logger software [C-LOGGER] Supporting the data logger software [C-LOGGER] that enables the graph display of recorded signal data, file saving, and dynamic transfer to the spreadsheet software program Excel Plug-ins for the dedicated libraries, the board also supports MATLAB and LabVIEW. We offer a dedicated library [ML-DAQ], which allows you to use this product on MATLAB by the MathWorks as well as another dedicated library [VI-DAQ], which allows you to use the product on LabVIEW. These dedicated libraries are available, free of charge (downloadable), on our web site.

Connecting these Signal Connection The procedure for connecting analog signals depends on whether the analog signals are single-ended or differential. The sections below describe how to connect the signals using flat cable and shielded cable. Single-ended The following figure shows an example of flat cable connection. Connect separate signal and ground wires for each analog channel on /B. Single-ended Connection (Flat Cable) BOARD /B Cable Signal Source 0..63 Ground The following figure shows an example of shield cable connection. Use shielded cable if the distance between the signal source and board is long or if you want to provide better protection from noise. For each analog channel on /B, connect the core wire to the signal line and connect the shielding to ground. Single-ended Connection (Shield Cable) BOARD /B Shield cable Signal Source 0..63 Ground If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise between channels. If the board and the signal source receive noise or the distance between the board and the signal source is too long, data may not be properly. An analog signal should not exceed the maximum voltage (relate to the board analog ground). If it exceeds the maximum voltage, the board may be damaged. Connect all the unused analog channels to analog ground. The signal connected to an pin may fluctuate after switching of the multiplexer. If this occurs, shorten the cable between the signal source and the analog pin or insert a high-speed amplifier as a buffer between the two to reduce the fluctuation. An pin may fail to obtain data normally when the signal source connected to the pin has high impedance. If this is the case, change the signal source to one with lower output impedance or insert a high-speed amplifier buffer between the signal source and the analog pin to reduce the effect. AD16-64(LPCI)LA 5
Differential The following figure shows an example of flat cable connection. For each analog channel on /B, connect the "+" to the signal and connect the "-" to the signal source ground. Also connect the analog ground on the board to the signal source ground. Differential Connection (Flat Cable) BOARD /B Cable Signal Source 0[+]..31[+] 0[-]..31[-] Ground The following figure shows an example of shielded cable connection. Use shielded cable if the distance between the signal source and board is long or if you want to provide better protection from noise. For each analog channel on /B, connect the "+" to the signal and connect the "-" to the signal source ground. Also connect the analog ground on the board and the signal source ground to the shielding. Differential Connection (Shield Cable) BOARD 0[+]..31[+] 0[-]..31[-] Ground /B Shield cable Signal Source If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise between channels. When the analog ground is not connected, the conversion data is not determined. If the board and the signal source receive noise or the distance between the board and the signal source is too long, data may not be properly. An analog signal should not exceed the maximum voltage (relate to the board analog ground). If it exceeds the maximum voltage, the board may be damaged. Connect all the unused analog channels to analog ground. The signal connected to an pin may fluctuate after switching of the multiplexer. If this occurs, shorten the cable between the signal source and the analog pin or insert a high-speed amplifier as a buffer between the two to reduce the fluctuation. An pin may fail to obtain data normally when the signal source connected to the pin has high impedance. If this is the case, change the signal source to one with lower output impedance or insert a high-speed amplifier buffer between the signal source and the analog pin to reduce the effect. I/O signals, signals and Control signals Connection The following sections show examples of how to connect digital I/O signals, counter I/O signals, and other control I/O signals (external trigger signals, sampling clock signals, etc.). All the digital I/O signals and control signals are TTL level Connection BOARD 10kΩ CN1 Cable Target Output Connection BOARD Output CN1 Cable Target IOL=24mA signal control The counter gate control (see Connector Pin Assignment in page 3-5) enables or disables the external clock to the counter. You can use this function to control the external clock to the counter. The external clock to the counter is enabled when the is "High" and disabled when the is "Low". As the pin has an internal pull-up on the board (or card), the default if not connected is "High". As a result, the external clock for the counter is enabled if this pin is not connected. Do not short the output signals to analog ground, digital ground, and/or power line. Doing so may damage the board. AD16-64(LPCI)LA 6
