confused about rain8

Postby kgingerich » Tue Jul 01, 2008 12:55 pm

The rain8net manual says the following:

"It is very important that no attempt is made to program any module that is still connected to the network".

It sounds like they are saying that if you want to connect the RS232 output of the rain8 to your computer that the rain8 must not be connected to the valves/network.

So how do you control the rain8 from ML if it can't be connected to RS232 while in use?

Obviously this can't be right but what am I missing?

Actually they mean connected to your sprinkler network.

Disconnect all sprinklers and power and sensors.

Attach the rs232 to your computer and the rain8 module
You do not need power for this.

Using the rain8 configurator software, set the module as unit 1,2,3 etc, default time for zones, etc etc.

Once completed, you are free to hook it up to zones, sensors, etc.

Thanks for the info, what i'm confused about is that if you can only hook up the rs232 to the rain8 when it's not connected to the sprinklers then what if I just want to make a quick schedule change via touchscreen? Surely I don't have to unhook the sprinkler valves to send programming info to the rain8?

do they mean that i need to only remove the 24v dc power when configuring the modules for the first time? Then after that, i can connec to 24v dc and also to serial on my computer and control via ML or their demo program or whatever?

right...first time setup only. From then on hookup as you wish.

I have two rain 8 net units running 24/7 with rs232 24/7 and it's fine.

btw, I do not use the rain 8 software for day to day use.

I use MLIrrigation with its rain8 drivers to configure, schedule, and manage. It's more powerful and completely flexible. The rain8 software is limited and not as feature rich.

You should not run them at the same time. For further support with the rain8 software itself you probably want to hit their website.

Thanks chris that's kinda the way i figured it was but the manual had me a little confused.

Did you have any troubles changing ID's on your second controller? I bought a couple of them and I can use their config software to read both module's fine but if I change the ID # to 2 and click LOAD it just says check the modem and that it failed. I only have it hooked up to the computer via their serial cable that came with it. I also tried 2 other computers with the same results. The green light even comes on when I'm reading the config and trying to load the new one but it still fails.

I'm going to give them a call today.

Thanks,
Kyle

It's working now, called WGL and they sent me an older version of the software which is working fine. Apparently the new 4.0 version has a bug.

great news!

Enjoy your new setup.

btw, one of the best features of the MLIrrigation setup is the seasonal adjust.

You setup your drippers or sprinklers physically with whatever flow or rate, and you set the time to deliver that flow for x minutes, but this feature allows you to more finely tune the length of flow based on season. So for those of us with dry summers and soggy springs, we can set spring flow to 50% and summer flow to 70% and fall flow to a completely different % to allow for those seasonal needs..
