User manual and programming manual SDK: http://www.dingtian-tech.com/sdk/relay_sdk.zip
This is a finished board, not a study board. Our default version don’t support flash by yourself, if you want to flash custom firmware, please leave a message ”send relay board with test firmware” when order
Relay Size:
2 relay: PCB: 87 x 68 mm Distance of hole: 80 x 60 mm Diameter of hole: 3.5 mm
4 relay: PCB: 91.6 x 86.4 mm Distance of hole: 85.3 x 80 mm Diameter of hole: 3.5 mm
8 relay: PCB: 122 x 87 mm Distance of hole: 115 x 80 mm Diameter of hole: 3.5 mm
Note: Please keep your computer ip is the same NETWORK SEGMENT as our default ip 192.168.1.100
Setting
Relay Connect
Support protocol Dingtian-String Dingtian-Binary Modbus-RTU., Modbus-ASCII, Modbus-TCP/UDP CoAP HTTP GET CGI(control relay, get input/relay status) Input Mutual Control MQTT(input/relay status change, report to your MQTT server auto)
Relay Task
Please sync the time on “setting” webpage firstly, you can config when relay ON and when relay OFF automatically
Input Link Relay
Input status change active relay ON/OFF, DELAY, JOGGING(PULSE),FLASH,TOGGLMOTOR To config “Motor” to control motor (blind)
Input Link URL
Input status changes will active HTTP URL
Input Relay Alias
Rename input/relay to understand better
IP WatchDog
It can ping and reboot other device when network is OFF
Transparent Transmission
Repost data which is from your device through our relay board to your PC from UDP/TCP to RS485/CAN,vice versa
Upgrade
Upgrade new firmware by webpage
Support Domoticz /Home assistant (HA Discover)/openHAB
IP Finder to search device, support different network segment
Connection Diagram
Default firmware
Q: what is the ip address? A: Ethernet ip: 192.168.1.100, user name and password both are admin WIFI-AP SSID: dtrelaySN, PWD: dtpassword, IP:192.168.7.1
Q: Where can I find sdk and manual? A: https://www.dingtian-tech.com/sdk/relay_sdk.zip
Q: How can I upgrade to latest firmware? A: https://www.dingtian-tech.com/sdk/relay_upgrade_tool.zip Please download and upgrade to latest firmware
Q: Why I cannot access the web through default ip? A: Please keep your computer ip be the same network segment as our default ip Default ip: 192.168.1.100, so your compute ip should be 192.168.1.x(x not 100)
Q: What can I do when computer ip is different network segment with your default ip? A: Option 1: change your computer ip to 192.168.1.x, x means any numbers from 2~254 Option 2: Change our relay ip through our IP Finder tool to keep the same as your computer ip
Q: Can I connect a rfid keypad reader to it via wiegand A: Our default firmware donot support, you can leave a message"send relay board with wiegand input firmware" when order
Q: Can you have separate input from the relay operation status A: webpage “input link relay”->”input control relay” to “NO”
Test firmware
Q: Can I flash custom firmware? A: please leave a message “send relay board with test firmware” when order”
