Here is another error message . If the ir signal is ok you get prompted for the next button. This sequence is repeated until all the listed buttons are recorded. You must then name and save the file which is saved is xml format. I found all was well for the nec format but my Panasonic vol up and vol down were learned okay but the recorded signals did not get recognised by Homevision. I tried relearning several times to no avail. That was a real pain as I had to go through the whole process again for 2 buttons...

Next was to close the reader application and open the tx unit software“ CIRCA”
And open either a new file or in my case an existing one. Now each ir signal could be allocated to a group but you would soon use up all your available groups. What I have done is created a group (18) called INFRARED. Now under the infrared group there is available 255 levels (I think) which I assume has more to do with dim levels but are being used to store ir signals in this case. As can be seen from the link I have saved several of my remote codes.

The Sanyo xml file now needs to be imported so I can load them into the ir transmitter which can hold approx 200 ir codes. There is quite a large library of ir xml files to choose from , but only select the files that you really need. The selected files are then updated and as can be seen in the next screen shot all the sanyo codes are ready to be selected and put into the “infrared” Group... Just need to drag each code across anddrop it off at the Infrared Group label and it places them in the transmitter list (LHS).

Now before downloading to the tx unit I need to program each code to transmit to only channel 2 . Other parameters can be changed and you can test the ir signal as well. When happy with the settings plug in the high speed programming lead and download the data and then its ready to use .. Its just a pity the Reader software is not a little more flexible and seems to stick to a rigid format which you should be able to tweak . For instance my programmable remote I use does not get recognised by the reader (AWA format) although works ok with HomeVision ..I had to use the original remote to learn the codes ..

The next task was to try and see if it would work as expected ie tx a zone signal via channel 1 and then an ir kit signal via channel 2 ... Tried sending my dvd mute signal , which was sent “TWICE” ... Turned out Homevision was picking up the signal sent by C_bus via the zone receiver. I have assumed this problem was caused by the tx signal being induced into the receiver wire as they are both in the same cat5. Was not a problem before as Homevision disables the receive function when its transmitting. But now C_Bus is sending the ir signal Homevision also receives it and sends it as well. I got around this by disabling the ir receive function for approx 1 second when a zone command received.

Today I decided to check further this induction problem as my current solution is not very elegent.. Tried all sorts of things and came to the conclusion it must be the ir receivers. so I replaced one with another ir receiver which I got from a different source than my normal supplier and the problem disappeared. So I have now replaced my receivers with these different ones and will test over the next few weeks. Have also removed the disabling commands in my ir events so if the problem surfaces again it will be quite noticeable More on C_Bus ir
