How to connect inductive loads

Serial commands

• Communication parameters - 8 Data, 1 Stop, No Parity, Baud Rate - 9600 bps
• Command for receiving the relays status:
  • Send "ask//".
  • 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 10 and LSB of byte 2 is Relay 16.
  • Example:
    • answer 1: 00 -> relays from 1 to 16 are OFF.
    • answer 2: 255(dec) 255(dec) -> relays from 1 to 16 are ON.
    • answer 3: 81(dec) 81(dec) -> 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
• Send sequentially:
  "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 "/" "/"
  1A(hex)=00011010(bin)
  05(hex)=00000101(bin)
  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 !

Denkovi Relay 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

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 16 1 status

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 16 all status

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

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 16 5 1

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 16 all 0

java -jar DenkoviRelayCommandLineTool.jar DAE0006K 16 turn 1010101010101010

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.

USB Relay Timer

USB 16 Relay Timer is software from Denkovi for all our USB 16 Relay Boards. 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 Relay Timer Manager 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 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.
