AC Jr. Serial Port + adaptor + LAN question

[JER-Z]

I am currently trying to decide on a controller and the AC Jr. w/ serial port is one of my options.

My new condo is prewired for Highspeed Internet with a central hub in the back of the coat closet and outlets throughout the condo, and a Ethernet Outlet is conveniently located behind where the tank is going. Will i be able to use a serial to ethernet adapter on the AC Jr. and get it networked w/ my LAN so i can use the aquanotes web capabilities?

This will be a deciding factor for me.

Thanks,

Wes

Yes, you should do a search as there are lots of threads that talk about that very subject.

yes. you will need a serial to ethernet adapter (expensive)

You can use the modified router we are talking about in this thread and not use the wireless part.

You'll have to connect the WAN port to your local network and configure it with a static IP (for the internet setup). I'll make sure there's a route between the WAN port and the RFC2217 server in the firmware.

there you go, now you can save money. It works too.
I have it working, following laurentm steps on the link he provided.

Here is what you would have to enter in the 'Edit firewall script' window to enable RFC2217 forwarding between LAN and WAN with the current firmware (v0.1). I'll add automatic forwarding support in the next release.

The router's configuration is assumed to be 192.168.1.60 for the WAN side (on your lan) and 192.168.2.0 for the lan network (router side). The router needs to function as a gateway.


iptables -D INPUT -j DROP
iptables -A INPUT -p tcp -m tcp -d 192.168.2.1 --dport 2000 -j ACCEPT
iptables -A INPUT -p tcp -m tcp -d 192.168.2.1 --dport 7000 -j ACCEPT
iptables -A INPUT -j DROP
iptables -t nat -A PREROUTING -p tcp -m tcp -d 192.168.1.60 --dport 2000 -j DNAT --to-destination 192.168.2.1
iptables -t nat -A PREROUTING -p tcp -m tcp -d 192.168.1.60 --dport 7000 -j DNAT --to-destination 192.168.2.1

There are many serial to ethernet adapters that are available, and have virtual serial port drivers. Here are couple that I found for about $100:

http://www.ipenabled.com/net232.html?source=goog&kw=serial+ethernet+rs232

I haven't personally used either of these, so I can't guarantee that they work, but the specs say they should.

A serial card is like $12 and a 50' serial cable is like $35. Sounds much easier and cheaper than modding a wrt54g or $100 for an adapter. Just a thought.

no thanks, i am not into having a cable running across the living room floor just to save a few bucks

Consider the ACIII it has a ethernet port built in. Really by the time you spent the $ making the Jr. work it wouldn't cost that much more and you get a few extra features too.
