Today I'll invite you to a peek into my home. To be more precise in my mobile home. Or more to my journey to a perfect mobile router setup. (Almost, I need to find the mounting plate again).
A few month ago I was asked by the GL.iNet staff if I would write about my Spitz AX mount in my RV. Life is unpredictable, so I don't got the time, even when I wanted to install it right after unpacking...
I tried it a few weeks ago. One day before my wife and I left for a company's conference, which means I needed to listen to motivational talks and she stayed nearby with the dogs... It was cold, I was tired.
First I installed the cable, put everything back in place, looks fine. I plugged in the Spitz aaaand no power ... Hmm. Even worse: Half of my RV gone offline... No heater, no fridge, no TV. Dammit. I don't want to tell my wife she is without heater this weekend. Believe me, I really don't want!
I found a melted fuse and changed it ... Uff, online again.
So I wrote to GL.iNet, I am sorry, this project will take even longer.
What I don't expected, a few nice people around the globe talked to eachother about my issue and the answer was 'maybe it is the wrong polarisation' ... Wow. Yes, the cable I used was not marked, so I assumed the plus and minus cable.
Today is a good day, I started over. At first I measured the original power supply:
Plus at the inner contact. Okay.
Afterwards I disassembled the panel.
The power to the TV is already fused. This helped me not the last time, but I used this cord again. Since we are using the TV one or two times a year...
The most important part is to measure again, after installing, before plug in.
If the polarization is wrong, the display will show a - (minus) before the value. In that case, don't plug in the router!
The voltage is with 13,2 V slightly higher than the 12,3 from the power supply . This is not an issue for the Spitz AX, which can handle 9 to 36 V in the data sheet. 13-14 V is normal for a healthy battery in the RV.
Now I just need to find the mounting plate.
This router is the perfect extension for my next RV trips. No USB-C converters, two SIM Card slots for private and business data card, powerful antenna, to get signal further away from cities.
And VPN to my home for a secure internet at any time!
