TEAC NT-505 impossible connecting to WiFi router o such LAN: help me please?

Hello mates,
I got my NT-505 3 days ago.
It seems to be working correctly but in my opinion all software in not the same level than the device: too aged & often no relevant documentation or support about.
However my big trouble is the NETWORK interface:  since first time I switched on, the NT-505 remains "for ever"  into NET configuring blinking state until it goes in power stand by.
Summarizing:

1. RJ45 cable is ok - tested in several manners
2. the wifi router (1Gb fiber connection) is ok
3. the wifi router ether ports (4) are ok - I checked a bridged LAN configuration too

Testing the NT-505 Ether port It results:

1. the physical level of protocol seems working correctly just on-way: the interface recognizes correctly the bandwidth (Fast ot Giga in my case) end the packet coming from the router are buffered. No packet sent  to the router.

2. At protocol level no ARP session are involved hence impossible retrieve MAC address and trying to do something.


VERY STUPID ISSUES:

1. Being NET board logically split from MAIN board It's need a separate firmware(!!!): how can I upload the NET firmware if, as stated into documentation, I must use the mobile app and It's impossible connecting the device to such LAN?

2. NO menu interface to configure manually the net parameters.

May someone help me (tricks..., recovery sw,..., low level maintance menu...,...) 

Thank you a lot.

I use the default XLR setting (Pin 2 I think).  I also have the Modwright LS100.  I'm not sure if it matters on the LS100 since it isn't truly "balanced", but if it does, your polarity will be inverted if you use the wrong setting.  I'd send Dan Wright an email and ask him which setting to use if you're concerned.

what greg said here - the LS100 manual states that xlr is wired "single ended" which essentially means there is no ground.

I suppose its possible that your speakers are wired in reverse, but I’m almost 100% certain that 2 hot would be standard positive in singled ended config.

To know which setting to select on the Teac XLR output, you need to know what the input device (e.g., amp, preamp, active speakers, etc) is expecting with respect to the XLR hot pin, and set accordingly.

Quick update after 4 months use of my replacement NT-505.

Wanted to quickly share my experience with my NT505. I've been controlling/listening to it via Roon, and so far the replacement unit works excellent. The sound is amazing! I really don't have a good base for comparison as all my previous DACs were from a way lower class, but I think for now I'm set and done with chasing the perfect DAC, as I can clearly see this is a quite deep rabbit whole :)

And to wrap it up... Based on my personal experience so far, and all mentioned in this thread so far, I just hope and keep my fingers crossed my unit will stay stable and I will not have any need for customer support as that thought just scares the living hell out of me.
Stay safe everyone!

@kosta68k. Glad to hear.  Mine has been stable for about 4 months now, since its repair.  Any issues have been with the Lumin app or my internet service.  My fingers remain crossed also.
