shield has two chip davicom dm9000aef and lp61114h.
how to connect this with arduino?
The Hanrun part is just the RJ-47 jack on the board. That is not relevant.
I don't find any useful information from a search of the other part numbers.
In the Arduino world, Ethernet shields use one of four Ethernet controller chips:
- Wiznet W5100
- Wiznet W5200
- Wiznet W5500
- ENC28J60
Are you sure your shield doesn't have one of those chips on it?
If not, please provide more information. A link to where you bought the shield would be helpful.
