- The WEL PCB was upgraded to Rev 3.2, to include a "1-Wire +V" supply
- The WEL Software was upgraded to Rev 2.0 which included a more robust
software update feature.
The files in this section relate to the current hardware and software

WEL User Manual 2.0. (WEL_User_Manual_2.0.doc) [[an error occurred while processing this directive]]
This updated WEL Users Manual was created to address the 3.2 hardware
and 2.X software. This manual incorporates BOTH the User Guide and the
Owner Setup manuals from prior revisions. It also includes a primer on
Network addressing as it relates to the WEL
If you use DHCP to automatically assign your WEL unit an IP address, you
may not know how to find it with your browser. Locate IP is a neat
windows program that will go out and find the WEL, and let you see (and
modify) it's IP address.
Image refresh scripts (WEL_images_refresh_scripts.doc) [[an error occurred while processing this directive]]
Your live system image and trend graphs are created and displayed on an
automatically-generated page on the OurCoolHouse server. But if you
have your on web site, then you may want to include them there as well.
Since the images are continually updated by the server, it makes sense to have them
automatically refresh on your web page. This file explains the best
way to get your images to refresh automatically. It's just some simple
Java Script that can be cut & pasted into your page.
Standard Sensor Names (WEL_Standardized_Sensor_Names.doc) [[an error occurred while processing this directive]]
One part of configuring the WEL is to give all your sensors names.
These names are used to define your system graphic and trend graphs.
This document suggests a standard naming convention.
User Software-Updates are possible on any WEL board running code version 2.0 or
This process requires you to download the UpdateManager program
and the latest WEL binary image. Once you have these files, follow the
directions on the Software Update Page.
Update Manager program (UpdateMGR.exe) [[an error occurred while processing this directive]]
This is a Windows XP program that locates the WEL on your network, then
enables you to load the new binary image into the on-board flash. The
existing image can be saved on the WEL as a backup in case there is a
problem with the new image. Download this program and put it in a "WEL_Update"
folder on your hard drive. Add a shortcut to the program on your
WEL Binary Image Rev 2.3 (OCH_WEL_2.3.bin) [[an error occurred while processing this directive]]
Thus update makes the WEB Post process more robust and corrects a bug
that effects the Humidity Sensor. Download this file and place it in
the same folder as the Update Manager program (see above).
WEL user guide. (WEL_User_Guide.doc) [[an error occurred while processing this directive]]
This is the original WEL user guide. It describes the hardware
features of the 3.1 version board, and it's a general introduction to the overall WEL concept. The manual describes the various
functions inside the WEL, and it shows how to connect up the standard sensors to the WEL screw terminals.
WEL Owner Setup. (WEL_Owner_Setup.doc) [[an error occurred while processing this directive]]
This document describes the process of setting up the WEL to post data,
and setting up the OurCoolHouse website to record and display posted data.
The WEL screens are bas on Revision 1.X software.
