Davicom DM9051NP

[srinair]

Hi All,

I am using a Davicom DM9051NP Serial TTL to Ethernet Module TCP/IP UDP Converter IOT RS232 RJ45 SPI Interface for STM32 Microcontroller W5500.

I have two questions:

1. When I connect this to an ethernet port on my computer I see a network interface (say, enp0s25) with a IPV6 address. I know that this board had a webpage from where I can control this device. But I am unable to find the IP address of the board per se. Could you please help me identify how I can access this webpage?

2. I connected a TTL device (from a FTDI cable - USB to TTL) to the TTL end of the DM9051NP and sent AT commands. Even the simple command, "AT", returns with a response of "+AT command error!!!". Is there any particular authentication sequence to set DM9051NP in AT command mode.

I am unable to find any documentation about this board in the internet. Could you please help me resolve the above issues?

Thanks!

Use ip scanner :

Advanced IP Scanner - Download Free Network Scanner.

Advanced IP Scanner shows all network devices, gives you access to shared folders, and can even remotely switch computers off. Download it Free.

www.advanced-ip-scanner.com

But its a subnet (not an expert here) of the router IP, so type "whatismyip" in your borwser to get
WW address. Or https://whatismyipaddress.com/

How to expose my localhost to the WWW? (port forwarding?)

I am running Apache/php on my localhost and would like to be able to make this publicly accessible from the internet. I think this is achieved by port forwarding? Can someone point me in the right

It must be connected to a router port to get a local subnet IP address via DHCP, or it must be manually configured with a static IP.

To find local addresses, get a copy of NMAP here:

Nmap: the Network Mapper - Free Security Scanner

Nmap Free Security Scanner, Port Scanner, & Network Exploration Tool. Download open source software for Linux, Windows, UNIX, FreeBSD, etc.

nmap.org

Run a hosts scan with that, it will list all the devices it can find on the local subnet, eg. "inside" your router firewall.

If you run scans with and without the new device connected to the network, you should be able to spot the addition & see its IPV4 address.

Thanks, Dana and rjenkinsgb. The documentation for the program on the DM9051MP board, IPSSP1001, gives all the information: file:///home/sree/Downloads/IPSPP1001%20UART%20to%20Ethernet%20user%20guide.pdf.

I was able to get the board working.

Have a great weekend!
