Hi, I am trying to connect a Ethernet to serial Rs232/485 converter/server to the Spectrum, UBEE cable modem part # DVW32C1. I have connected the Ethernet side of the converter to the Ethernet cable Ethernet port 2. I can connect to the WiFi of the converter server via my laptop and access the internet via the cable modem but I cannot get to the converter config at 10.10.100.254 and mac address d8:b0:4c:d3:05:de. I can connect to the UBEE at 192.168.100.1. So how can I configure this pair so that I can access the converter serial port from the internet with a IP/port, etc.?

Get what you want to do to work on the LAN connection of the UBEE. Then you can move on to getting it to work via internet.

I am not familiar with either of these devices either. But apparently your "IT guys" aren't very good. They SHOULD have given you exactly the same advice. Read the user's manual. Set the IP address, disable any DHCP server. Get your connectivity to work via LAN.

To access the serial port server, you would have to do a few things.

  • ■ Set the serial port server to a static IP in the same subnet as the modem (192.168.100.x) but outside the DHCP range of the modem/router -- You might have to take a laptop and manually set the ethernet to a 10.10.100.1 address and directly connect to the serial port server to change the IP address.
    ■ Setup a DDNS account for the modem/router
    ■ Port forward to the serial port server on the modem/router
    ■ Access the serial port server via myDDNSAddress.noip.com:xx where xx is the port number you forwarded

You asked about internet access. To me that means from somewhere outside your LAN. I gave you basic steps on how to do that.

You will have to explain better what function you are trying to accomplish with this serial adapter to give you better info.

No. If you want help, you will have to figure out how to verbalize it here. You haven't even said what brand serial port adapter or what you have it connected to.

What FUNCTION are you trying to accomplish? There aren't too many devices that use a serial port any more.

From what I read, serial port server IP address is 10.10.100.254, while computer and cable gateway (router) are at 192.168.100.x. Under these circumstances, your computer just can't reach the serial server.

I would change serial server' IP address to be from same 192.168.100.x network:
- temporary, assign manual IP address to your computer like 10.10.100.100, and connect it directly to the serial server
- confirm you can "PING 10.10.100.254"
- find out how you can change Ethernet settings of your serial gateway. There could be a WEB page, or special utility for that

No problem. The convertet is a USR-WiFi232-610. The serial device is a standalone M2M module that we communicate remotely through the internet. This setup is for remote site development so my IT guys can access this M2M device over the internet at my home using the Spectrum UBEE cable modem and the ethernet to serial converter. Hope this helps.

OK. Chapter 6 of the user's manual -- http://www.usriot.com/download/WIFI/wifi-232-Convert-Server-V2.0.3-EN.pdf talks about configuration.
You will need to change the IP address from the default 10.10.100.254 to something in the 192.168.100.x range -- I would recommend 192.168.100.254.
Paragraph 6.1.4 talks about setting the LAN IP address. You want to DISABLE DHCP because your UBEE modem will take care of DHCP duties.

That change should make the device accessible while connected to the LAN on the UBEE modem/router. (that was step #1 in my very first post) ...

To make internet access possible you need to do the additional steps I outlined. Those steps will make the serial adapter accessible from the internet.

You say you have "IT guys"... Why aren't they helping you ???
