Support Customized and develop by our company
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 dont support flash by yourself,
if you want to flash custom firmware, please leave a message send relay board with test firmware

when order

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
