Popular Post gstew Posted November 25, 2019 Popular Post Share Posted November 25, 2019 An ER Firmware Upgrade experience… Alex sent it to me as I had an interesting issue with my somewhat unique setup when I first put in the ER a couple of weeks ago. I have a very simple setup with no streaming and not even a connection to the Internet. I have a Zotac picocomputer I use as an file server (Logitech LMS server) and an old 2.4G WiFi router I use as an access point for connection via a cellphone to control the system. They were both connected to a ZyXEL switch which fed a sending Trendnet FMC (sounded better than the TP-Link ones I had here) and that connected to fed a slightly-modified DeLock receiving FMC (added a 3.3V regulator on board so I could feed it with a good linear supply instead of the included SMPS). When I got the ER, I pulled the 2 FMCs and the ZyXEL switch out and connected everything to the ER. I could not get a connection to the file server via the WiFi even though the lights on the jacks were blinking. I played around with it a little and found that bringing the ZyXEL switch back, connecting it to the ER, and connecting EITHER the Zotac file server OR the WiFi Router through the switch to the ER A side worked ok. Weird! I’d been in touch with Alex about the issue (it is such an un-common system that I didn’t want to trouble-shoot in the forum) and he sent me the firmware update to try. First, Alex’s instructions were flawless and it worked like a charm as described with no issues. Second, when I pulled the ER to do the update, I just connected everything back into the ZyXEL. Instant SQ drop. YUCK! I’m GUESSING that was due to the increased noise fed via the Ethernet connection into my endpoint even though the bits being played were ones still in the buffer that had been transmitted via the ER (my setup will play several minutes after disconnecting the input to the endpoint). I did the firmware upgrade and went back to the system. It might have been my imagination, but the SQ drop seemed larger. Possibly because now the bits being played came through the ZyXEL with no ER regeneration. DOUBLE YUCK!!!! I put the ER back in with the setup configured just like before and things worked as before. Then I tried reconnecting everything through the ER and now it worked ok without the ZyXEL switch! Happy camper. AND my impression was that the overall SQ went up a notch post firmware update. Most notable was better definition and dynamics at very low levels (while my wife is home and I can’t play it as loud as I like). A winner got even better!
