We've released new versions of our iLearn, iTest, and iConvert utility software:

iLearn 2.7 fixes the issues seen in versions 2.5 and 2.6, where attempting to learn codes could result in unpredictable or lost results.  The interface has also been restructured.

iConvert 3.3 introduces the ability to convert to and from GC Compressed format codes, as well as the GC and Hex formats it has previously supported

iTest 1.3 has been cleaned up a bit, but is generally functionally unchanged.

All of these are now built on Microsoft .Net 4.0, upgraded from .Net 2.0.  On some systems, you may need to update .Net, as a result.

It has recently come to our attention that Microsoft made a breaking change in Windows 8.1 Pro and removed ad hoc networks from its available wireless networks list. There has been much complaining about this change in the Microsoft forums (Google 'windows 8.1 cannot see ad hoc'), but to our knowledge, Microsoft has not responded.

This introduces a hurdle to configuring the iTach and iTach Flex WiFi-enabled units since the initial configuration requires access to the temporary ad hoc wireless network that the unit broadcasts.

The good news is that you may still be able to connect using your Windows 8.1 computer. We have found that many manufacturers of WiFi adapters provide their own connection software that will usually allow you to view and connect to ad hoc networks. Unfortunately, this is dependent on the specific manufacturer and their choices in hardware and software development. There are thousands of possibilities in this area, and we have no information on compatibility or functionality of specific WiFi manufacturers or adapters.

As a reliable workaround, we recommend using another WiFi enabled computer or mobile device with a browser to connect to the ad hoc wireless network and then use its browser to set the initial network configuration. Once the unit is connected to your regular WiFi network, you can use the Windows 8.1 computer to access the device configuration via a browser or use our other Windows based tools ( to discover and test the unit.

Recently, an issue arose which caused a group of iTach WiFi units (primarily the WF2IR) to get stuck in their initial boot and continuously reboot. This is characterized by the unit flashing all LEDs as it initially boots, waiting a moment, then flashing all LEDs again repetitively (delay, flash sequence, delay, flash sequence etc). The cause of this problem was an isolated batch of a wireless related part, which has been fully filtered from our production process for some time and is no longer a continuing issue. If you have one of these units or have gotten one in the past, we apologize for any inconvenience this caused you. If you see your unit present this symptom, send a message to us with an explanation that you are getting the continuous reboot, as well as your shipping information, to and we will swap out your unit for a fresh one from our facilities.
