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 !

 

Where to find the device

The device will appear in your computer as USB Serial Port

 

 

DRM Software 

Denkovi Relay Manager (DRM) is universal software for controling all kinds of Denkovi USB, VCP and SNMP relay boards

 

DRM Software will hep you to save money for expensive softwares 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 one of our relay boards from this list you may turn your PC in powerful automation tool.

USB 16 Relay Manager

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

 

Step by step guide for connection and using the USB 16 Channel Relay Module - RS232 Controlled

1. Connect the USB 16 Channel Relay Module - RS232 Controlled to the PC USB port with USB cable
2. Supply the USB 16 Channel Relay Module - RS232 Controlled with 12 VDC. Be carefull - THERE IS NOT PROTECTION AGAINST VOLTAGE INVERTION !
3. If you use FTDI for first time, you may need to download the drivers form here, and after that install them or visit http://www.ftdichip.com/
4. Download USB Relay Manager for controlling this board - it works with Windows XP, Windows Vista and Windows 7
5. You have to choose the relay board from the dropdown list of USB Relay Manager
6. Wait several seconds. You should see green bar at the bottom of the window.
7. Good luck !

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. Download it from here.

BCB Com Port Tool 

BCB Com Port Tool is open source application for RS232/RS485 communication

 

This is windows application that allows you to test not only the USB 16 Channel Relay Module - RS232 Controlled but any other RS232/RS485 device. You can send and receive data easily, adjust the COM port, baud rate and so on. This project is open source and its main purpouse is to help you developing your own RS232 application.
