This is relay board with 16 SPDT Relays controlled vis USB. It is suitable for controlling electrical devices, water jets, motors and so on. It may be integrated in small home automtion and robotics projects. It uses one USB port of your PC and it is controlled via serial RS232 commands. It is shown on your PC as Virtual Com Port (VCP). This item is supported by DRM Software (now available for Windows and Linux 32/64). Although the communication is easy to be done in every programing language, we can provide many software examples in different languages.
Software examples: VB6, BCB6, Java, .NET 2010 Express, LabVIEW. Please contact with us for download.

USB 16 Relay Timer - Relay Timer from Denkovi for all our USB 16 Channel Relay Boards. CD is not included in the package but the software is available for download from this link -USB16RelayTimer.exe
Initially all the relays are always OFF
The relay board can not work without computer but if the USB cable is unplugged, the relays keep their states.
The USB Relay Board appears in Device Manager as Virtual Com Port (VCP)
Communication parameters - 8 Data, 1 Stop, No Parity, Baud Rate - 9600 bps
Command for receiving the relays status:
The answer is two bytes - byte 1 and byte 2. Byte 1 represents relays from 1 to 8. MSB of byte 1 is Relay 1 and LSB of byte 1 is Relay 8. Byte 2 represents relays from 9 to 16. MSB of byte 2 is Relay 9 and LSB of byte 2 is Relay 16.
answer 1: 00 -> relays from 1 to 16 are OFF.
answer 2: FF(hex) FF(hex) -> relays from 1 to 16 are ON.
answer 3: 81(hex) 81(hex) -> Relays 1,8,9,16 - ON, the rest are OFF.
Commands for single relay setting:
"01+//" - Relay 1 is switched ON
"01-//" - Relay 1 is switched OFF
"02+//" - Relay 2 is switched ON
"02-//" - Relay 2 is switched OFF
"16+//" - Relay 16 is switched ON
"16-//" - Relay 16 is switched OFF
Commands for all relays setting:
"on//" - All relays are switched ON
"off//" - All relays are switched OFF
Command for many relays setting
"x" - as a char a - as HEX number. a[0;FF]. This number correspondends with relays from 1 to 8. The MSB is relay 1. b - as HEX number. b[0;FF]. This number correspondends with relays from 9 to 16. The MSB is relay 9.
"/" - as a char. This is the first part of the delimiter
"/" - as a char. This is the second part of the delimiter
Example (a=1A(hex) and b= 05(hex) )
"x" 1A 05 "/" "/"
Relays 1,2,3,6,8,9,10,11,12,13,15 - switched OFF
Relays 4,5,7,14,16 - switched ON
Note that there must be minimum 5ms interval between each two commands !
.NET VB Express 2010 Open Source Example
This is very useful open source application for testing and understanding the USB 16 Channel Relay Board. It will help you when you want to develop your own Visual Basic (.NET) application :)
This is Visual Basic Express 2010 example application demonstrating all the Relay Board commands. It uses the built-in Serial Port control.
You can easily test your USB 16 Channel Relay Board or modify the GUI as you want. It demonstrates every command and you may see in real time what is sent to and returned from the USB Relay Board.
This is only basic application and does not include threads and any complicate mechanizums. It will help you to build your own application saving of your time.
We can provide BCB6, VB6 and Java source as well by your request... please contact with us.
Control Relays from Command Line
Denkovi Relays Command Line Tool
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
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 16 2 status
java -jar DenkoviRelayCommandLineTool.jar DAE0006K 16 all status
Demo video how you can control the USB 16 Channel relay board from command line, browser and tablet the same time because of our command line tool.
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)

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
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 supported by Windows 8 and Linux)

USB 16 Relay Timer
USB 16 Relay Timer is software from Denkovi for all our USB 16 Relay Boards
CAUTION! Using of USB 16 Relay Timer with devices which are not manufactured by Denkovi Assembly Electronics LTD is not allowed!
We developed this application because sometimes we need to switch on for example this relay for 5 sec or switch off that relay for 2.2 sec. With this USB 16 Relay Timer you can do such operations with resolution about 100 ms. You can add very larg number of states and each state can take delay from 100 ms up to 999,9 sec. The interface as you see is user-friendly and you can save or load your project (in .txt format). This system (USB 16 Channel Relay Module - RS232 Controlled plus USB 16 Relay Timer) is suitable for small christmas light displays, home irrigation systems, also you could find solution of problems in the automation when it is required some sequence of different states and many others.
