As promised, I am providing some additional helpful instructions to assist in the installation of the 2808/988 firmware update dated 02/08. Refer to this
post for obtaining both 2808/988 updates.
1. I have an older Toshiba laptop which does not have a serial port so I ordered a generic USB-to-Serial DB9 off the internet from here
for $10. The posts on the serial DB9 end do not twist off, so I had to pull them off with a pair of pliers as the posts on the Denon serial jack cannot be removed. This particular cable is only 18" in length which was fine for me, however, it might be easier with a longer (e.g. 3' cable) depending on your own setup. Upon receipt of the cable I hooked it up to the Denon. My WIN XP OS recognized it as new hardware, however, initially I was not able to find a driver for it on my Toshiba installation/driver CDs, although I did find a reference on the internet that for WIN XP a driver was not needed (even though my OS indicated the hardware might not work properly). I let it go and figured I would try it anyway without a driver.
2. Once the update was received, I downloaded the attachment to my laptop.
3. I clicked on the firmware update folder. There are 3 files in the folder of which I used two, the PDF file (instructions) and the zipped setup file.
4. Open the PDF file to review the instructions. At the bottom of the file, it shows how to look at the configuration file to see what the current software version is. The picture in the file shows what it will look like after the update, however, you might want to write down what the original version setting is.
5. Open the zipped setup file to install the software onto my laptop.
6. Click on the icon placed on the desktop to start the firmware software. A popup is displayed which allows you to check the various COM ports to determine which one works. None of them worked except COM3 so I selected that and clicked on the Update button. It ran for a few minutes before coming up with a communication error. In the instructions it gives you an alternate procedure if the first one fails. I tried this and it failed as well.
7. Since the error was a communication error, I went back to the internet and looked for a USB-to-Serial driver and downloaded this one (PL2303
), which worked successfully for me although it indicated it was installed using COM8 which is what I selected when I ran the procedure again (rather than COM3).
8. I repeated the update procedure starting from the beginning and it worked successfully this time, taking about 25 minutes for the update to complete.
9. I received a "Update complete" popup and upon running the configuration file, found it to read the same as listed in the PDF instructions.Firmware update changes
1. The "Cars" BD disc has a Dolby TrueHD 6.1 soundtrack, however the display read and playback only HD 5.1 - this is corrected.
2. The 'New Line' titles with dts-HD Master 7.1 tracks are played back in PCM 7.1 however the display only shows dts Surround 5.1 - this is corrected. It will show dts-HD MA 7.1.
3. Intermittent IR operation of certain commands through the Room to Room back panel jacks - this is corrected.NOTE: So unless you have a 6.1 or 7.1 setup or are having IR operation problems, this firmware update is not necessary.
