1. Version 2.16 of the firmware was released to improve network connections, increase posting resolution, and add new Yearly accumulation modes.
2. User Manual Rev 2.5 was released to document the new capabilities of this hardware/software combination.
3. Update Manager Rev 1.8 was uploaded to the website to support the latest WEL firmware.  This MUST be used to load new firmware on any WEL above WEL0168

Scroll down to the Legacy Files section for manuals for prior hardware and software.

WEL User Manual 2.5. (WEL_User_Manual_2.5.pdf)  [27 Apr 09]

This updated WEL Users Manual was created to:

• Document the new WEL 2.16 Firmware features.

LocateIP (LocateIP.exe)

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.

Wiring tips for WEL sensors (WiringQuickTips.pdf)  [24 Mar 09]

This is a short document that summarizes how to hook up the various WEL sensors. 
It describes the standard wire color-code and explains the signal polarities.

Image refresh scripts (WEL_images_refresh_scripts.doc)  [20 Nov 06]

Your live system image and trend graphs are created and displayed on an automatically-generated page on the WELServer 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)  [20 Nov 06]

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.

Sample logfile (WEL_log_2008_09.xls)  [02 Sep 08]

This is a sample Log File. It contains just over a day's worth of data for eight devices. Each row for the file is one Data Post.  The row starts with Date and Time and then follows with each device that is listed in the Log Order section of your Owner Setup, separated by tabs.  Although the file has an .XLS extension it's really just a text file, but the .XLS extension causes Excel to be run when you double click the file.

User Software-Updates are possible on any WEL board running code version 2.0 or greater. 
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)  Rev 1.8   [24 Apr 09]

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 desktop.

Note:  If you have downloaded this program before, make sure you download this latest version if you are updating WEL firmware 2.16 or above.

WEL Binary Image Rev 2.16  (OCH_WEL_2.16.bin)  [24 Apr 09]

Download this file and place it in the same folder as the Update Manager program (see above).
New features include:

• Added the ability to edit accumulated values.
• Made Ethernet Startup more robust (retrying if no router present)
• Added Yearly accumulation.
• Changed Web Post data resolution to 2 decimals.
• Switched to latest Download Manager Library.
• Began adding support for second 1-Wire network.

NOTE:  Once version 2.16 has been run once, you cannot rollback to any version prior to 2.13.  This is due to the increase in device slots.

NOTE:  Once version 2.13 has been run once, you cannot rollback to any previous version.  This is due to the increase in device slots.
