PARxCH SOFTWARE

Site Map > PARxCH Software

A complete software package comes free with each of our 24 bit 1/4/8 channel data acquisition systems. This package includes finished applications, diagnostic programs, low level libraries and source code. Plus, the latest updates are always available at no charge from our downloads page.

The PARxCH software can be used with any and all of members of our PARxCH family of 24 bit A/D products including the PAR1CH, PAR4CH, and PAR8CH. With this software, you can start acquiring data right away. If it doesn't completely satisfy all your acquisition needs, you can customize the source code for your application. Or, check our list of third-party software programs to see if any fit your needs.

Software Summaries

SAMPLE SCREENS: Meter, View (showing PAR8CH data)

SIMP
This is a simple "text only" acquisition program. Acquisition parameters such as sampling rate, gain, and output file size are specified in ASCII form in an initialization file. Acquired data can be presented on the screen as text values and saved to the hard disk in binary multiplexed format. This program is perfect for applications where the acquisition will run unattended or for lower power PCs where a complicated GUI interface would be excessive.

SCOPE.EXE
This is a full Windows GUI interface program that displays acquired data as horizontal traces on the screen. Acquired data is scrolled across the screen as it comes in and is also saved to disk. All acquisition parameters, such as sampling rate, gain, and output file size, are set by dialogs reached from pull down menus. Hot keys like up and down arrow can be used to adjust the number of displayed bits for the signal level you are using. The binary file format is exactly the same as for simp.

VIEW.EXE
This is a full Windows GUI interface program that displays previously acquired data as horizontal traces on the screen. Scroll forward and backward and from one sequential file to the next with a single key press. Hot keys like up and down arrow can be used to adjust the number of displayed bits for the signal level you are using. Works for both .out and .dat format files produced by simp and scope.

METER
This is a simple text only program that displays acquired values as voltages on the screen. Data is presented the instant it becomes available as it would be with a typical DVM. The program includes individual channel calibration.

DIAG
The system diagnostic can be used after installation or any other time to verify that the A/D board is correctly connected and communicating with the PC. This utility can prove very valuable in the field when connecting new hardware.

TWO TASK SUPPORT
Under multitasking systems like Windows and Linux you can run acquisition as one task while a second task examines the acquired data files and performs further processing. Typical second task activities might include items like triggering accept/reject decisions on files so an excessive amount of data does not build up on the hard disk. The 2task example included with the system shows how to run a simple threshold trigger. Under Windows, the two tasks are typically run in separate windows. Under Linux, the acquisition task usually runs in the background while the processing task runs in the foreground.

LABVIEW SUPPORT
LabVIEW drivers and finished applications paralleling the other software are provided. The applications are a finished scope acquisition and LED meter display program. These programs are "ready to go" and do not require any user programming, but you must have a copy of LabVIEW in order to use them. Full LabVIEW "G" source code is provided.

LIBRARY SUPPORT
Basic driver support is provided as a collection of library functions that let you initialize, start acquisition, and copy results to the PC. The library source code can be compiled to either static or DLL (shared library) format with no changes and is written in standard ASCII C. See below for a list of functions.
