Free external serial device control software for windows

Device Monitor is a free utility that allows you to view the status and the program modbus devices connected to the serial port. Monitored parameters automatically updated based on the timer setting.
This tool is for Microtrend hardware modules, but can be used for any modbus modules. RPM, production, counters, voltage, current, temperature or any process parameter can be remotely displayed.

Lalim Parallel Port Control can control hardware through the parallel port (printer port) and can also control a remote PC parallel port through a network.
Most of engineering industry using PC to control hardware with using additional I/O card but with Lalim Parallel Port Control you can use your default printer port controlling external device such as switching on/off light or control electronic devices.
What does this program [does is] trigger the parallel port (Printer port) s data pin by your command. For example when you trigger pin2, your printer ports pin2 becomes +5 volt.
With this +5 volt, you can build your own electronic circuit to drive other external device. You can also built a simple circuit to test it by connect a LED with 1 kohm resistor direct to it pin.
Lalim Parallel Port Control requires a certain knowledge of electronics and if you are not comfortable with a soldering iron, or dont know what a 1k resistor is, then it is probably advisable that you do not attempt to use this program.
If you are capable working with DC electronics, Lalim Parallel Port Control allows you to build remote-controlled, or timed, devices for your home or office ? turning on or off the air conditioner, adjusting lighting, opening & closing windows, monitoring burglar alarms, and more.

Lalim Parallel Port Control Basic 3.4 is a powerful tool that can control hardware through the parallel port (printer port) and can also control a remote PC parallel port through a network.

IC Imaging Control is an ActiveX, C++ Class Library and .NET component that allows programmers, developing under Windows 2000 and Windows XP, to directly access any DirectX compatible image source. Features: live video display: set parameters, scroll and zoom, graphics overlay, ring buffer, video codec support, trigger support and supports multiple devices. A free evaluation version is available for download. IC Imaging Control also boasts a well visited discussion forum that ensure that all support issues are dealt with in a timely fashion. Device Control functions: Selecting WDM Streaming Devices directly; Selecting WDM Streaming Devices via Built-In Dialog; Brightness, Contrast, Saturation, Gain etc; Zoom, Focus, Iris, Pan/Tilt/Roll; Support for DCAM and other Properties not defined in DirectX; Built-In Dialog for Manipulating all Properties; Serial Numbers; Functions to Save and Restore all Properties of a Device; Horizontal / Vertical Flip; DV Drive Control (play, stop, freeze, fast forward, rewind); Frame Rate Adjustment; Trigger. Output: Real-time Video Preview; Overlay; Scroll and Zoom; Acquisition of a Single Frame; Save Image to File (BMP, JPEG); Acquisition of an Image Sequence; Ring Buffer; Event controlled Image Processing; Capture Pause; Timestamps; Assign Image Data to other Controls; Direct Image Buffer Manipulation with VB Array Syntax; Acquire to AVI using codecs; Codec Parameterization.

JComm is created to capture data from the serial port of your PC, tokenize the data and then export the data into a text file with user defined delimiters.
Once the data has been exported to a text file, the user can then easily import the file into popular databases and spreadsheets such as Microsoft Foxpro, Access and Excel by using the import wizards provided with those applications.
Main features:
- User Defined Delimiters
- Event Driven
- Save Data to Text Files
- Can Send Commands to Serial Devices
- Commands can be sent to serial device with an interval timer
- View window to monitor data integrity.
- Designed to use for data logging and data acquisition.
