Denkovi Relay Manager (DRM) is multiplatform software for easy controlling all kinds of Denkovi relay boards (USB,SNMP,TCP/IP)

CAUTION! Using of Denkovi Relay Manager (DRM) Software with devices which are not manufactured by Denkovi Assembly Electronics LTD is not allowed!

The item is supported by DRM Software. DRM Software will hep you to save money for expensive software and time in programming. It allows you to switch ON/OFF your devices at particular date and time, turn ON/OFF the relays with pulses or control them via specific sequence. If you have ordered at least one of our relay boards from this list you may turn your PC in powerful automation tool.

• Multiplatform software: supported by Windows/Linux (ver. 2.0)
• Control up to 32 relay boards
• User-friendly intuitive interface
• Save/Load file
• Control mode: single and multiple setting of the relays
• Single pulse with adjustable delay from the control mode (ver. 2.0)
• Timer mode: create timer playlist for the relays
• Weekly mode: each relay may be turned ON/OFF on each day of the week
• Calendar mode: each relay may be turned ON/OFF on particular date at particular time
• Pulse mode: each relay may work in pulse mode by setting duration for ON and duration for OFF. Adjustable number of pulses (ver. 2.0)
• Each relay from each relay board can work independently in some of the five modes
• Each relay board and each relay can be named by the user
• Indicator panel
• Auto load function - the last working file is loaded when DRM is started
• Auto connect function - when the relay board is disconnected DRM will keep trying to find and when this is done, the relay board will be connected again
• Auto start function - DRM software starts when the OS starts (currently this is not available for Windows 8 and Linux)
• Auto set function - DRM will set the relays automatically when the relay board is connected
• Possibility of DRM to starts when PC boots and continues to work from the last saved point

The main goal of this project is to help you to use our USB relay boards easily and without any specific knowledge how do they work. This tool is actually shell for all our USB relay boards and it does not matter which is the relay board, the command is the same. Just type one command and the the tool will set, get relay status or even will take temperature value from the board sensor (if any). It can be integrated in other software and you don't need to know much about how the USB relay board protocol. With this tool it is like a "game" and it takes literaly minutes to create for example PHP script and control the USB relay board from smartphone browser.

Typical applications for this software are:

• Create desktop icons to turn particular relays
• Create BAT/BASH files to make more complex logic (like timers for example)
• The commands can be executed from PHP script
• Control our USB relay boards from Android / iPhone mobile devices
• The USB relays can be controlled from each software/platform which can run external executable files or commands in command line promt

Example commands:

LIST COMMAND - lists all devices connected to computer.

java -jar DenkoviRelayCommandLineTool.jar list

STATUS COMMAND - display relay(s) status(es).

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 8 1 status

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 8 all status

SET COMMAND - set relay(s) state(s).

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 8 5 1

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 8 all 0

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 8 turn 10101010

TIMER COMMAND - exectues time-critical operations. Well known fact is that every time when we run the command line tool the jvm is runned and this takes significant time. Many users contacted us with requests to execute timer commands for time-critical operations. That's why we added such command. It can perform single pulse, many pulses and even cycles with more complex sequences of pulses and every pulse can be with different time (in miliseconds). Please note the state bits must be equal to the relay numer!

java -jar DenkoviRelayCommandLineTool.jar id=1 4 timer 1,1111,10,0000,50,1111,25 //makes all relays ON for 10ms, all OFF for 50ms and all ON for 25ms

java -jar DenkoviRelayCommandLineTool.jar id=1 8 timer 5,11111111,10,00000000,100 //makes all relays ON for 10ms and all OFF for 100ms - 5 times

java -jar DenkoviRelayCommandLineTool.jar id=1 16 timer 5,1000000000000000,10,0000000000000000,1000 //makes first relay ON for 10ms and OFF for 1sec - 5 times

USB 8 Relay Manager is application for controlling USB Eight Channel Relay Board

CAUTION! Using of USB 8 Relay Manager with devices which are not manufactured by Denkovi Assembly Electronics LTD is not allowed!

This is application that allows the USB 8 relay board to be controlled from your PC. There is two modes - Manual Mode and Timer mode. You may open many USB boards and select wich one to control. There are 8 indicators representing each relay channel led from the board.

Manual Mode

By selecting this mode you are able to select wich relays are turned ON and wich OFF with 8 buttons.

Timer Mode

With this mode it is realized way of automation controling. You may create your own algorithm, suitable for your project and run it. Delays and states may be given. You may adjust the timer resolution. You may save and load your own program.

Denkovi JExtraPack is packet from 3 applications for our device - USB Eight Channel Relay Board

CAUTION! Using of Denkovi JExtraPack with devices which are not manufactured by Denkovi Assembly Electronics LTD is not allowed!

Denkovi JExtraPack contains 3 applications. Each of these applications are written in Java, so JVM is required. Each application can control up to 10 USB relay boards so you will need of course FTDI VCP drivers. We provide single installation file and everithing is included in it.

Manager

This is manager that allows simple and easily toggling the relays. It contains eight relay toggle buttons and two for all on/off. The application can handle up to 10 USB Relay Boards at a time. The main advantage is that you can select which board to control and toggle the exact relay. On the first image right to the text it is shown how sholuld look like the normal running application.

Timer

This is windows application for switching on/off up to 10 relay boards with your PC. You can give different states, sequences and delays for each relay and each connected board on your PC. You can save your algorithm in file and load it.

Alarm

This is windows application for switching on/off up to 10 relay boards with your PC. Each relay can be set on/off depending on the date and time. You add, change or delete states. You can save your schedule in file and load it.

Each such board is shown as separate virtual com port (VCP) on your PC. The relay board outputs are controlled by FT245RL. It has 8 bit data output register. When data is sent to the register the outputs are set. Be sure "Synchronous Bit-Bang Mode" is selected! Also the baudrate must be set with high value - 921600 (to avoid the latency if any). FTDI provides Bit-Bang Mode documentation. See this. The board can not be controlled directly via COM port - it is need to have special applications downloadable in this auction. For software examples, please contact with us.

Important:

• The item can not work without computer.
• The board can not be controlled directly via COM port - it is need to have special applications downloadable in this auction.
