How to connect receiver to mainboard?

@Bernard Thank you. That picture would have saved me some of the trouble in the recent days :/

So I have to connect the center sensor to "P. Left". There was no wiring diagram anywhere so I assume its:
Board Pin 1 (5 VP) -> Solder to sensor VCC
Board Pin 2 (GND) -> Sensor screw connector GND
Board Pin 3 (?) -> Sensor connector OUT

What's the current documentation? So far I found: http://wiki.ardumower.de/index.php?title=Perimeter_sender_(English) http://wiki.ardumower.de/index.php?title=Perimeter-Schleife http://wiki.ardumower.de/index.php?title=Perimeter_wire_ru http://wiki.ardumower.de/index.php?title=Schleifensender http://wiki.ardumower.de/index.php?title=Perimeter_wire http://wiki.ardumower.de/index.php?title=Azurit_Firmware_(English)#Perimeter_receiver http://wiki.ardumower.de/index.php?title=Azurit_Firmware_(Deutsch)#Schleifen-Empf.C3.A4nger http://wiki.ardumower.de/index.php?title=Der_Perimetersender_ohne_automatische_Regelung

I just noticed that the english documentation lacks a lot of information :angry: - the information about the amplifier is missing and the troubleshooting as well - that's no fun!

Here's a diagram about the sender: http://wiki.ardumower.de/index.php?title=Datei:Schleifensender_Ardumower_V2.JPG What's the status of this document? What is ACS712 (current sensor I guess?)

Which direction do I have to connect the perimeter loop? According to some pictures I guess it's M1OUT2 Clockwise and M1OUT1 Counter-clockwise. Am I correct?

Are there instructions about installaing the perimeter wire? What are the distances to walls/steps? What's the recommeded shape to go around a corner? Are the limits about angles and bend-radii?

What's the most current instruction about the charging station? Is the mower expected to drive through the station? Or shall it be a dead end? May I install the station in a corner (so that the mower can enter in a straight line). Where shall I place the clockwise wire so the mower doesn't see it when entering the station? (I guess I'll have to provide a picture).
 
Connecting is OK.
Documentation ,The first link is Ok
Diagram with ACS712 is not OK , it is old post, the current sensor is ina169 in the last sender v2.
M1out1 and M1out2 is easy .Put the mower inside the area and check into mower arduremote setting perimeter that the mag is negative(it indicate that the mower is inside),if no invert m1out1 and m1out2.
 
Thank you.
The first link doesn't mention the configuration line:
#define USE_CHG_CURRENT 1 // use charging current sensor for robot detection? (set to '0' if not connected!)
So I guess this is default and no longer required?

It also lacks the whole chapter "Einstellungen" from the German page.

Can you give me a hint where I can find the recommended bend radii and distances for the perimeter wire?
 
For the sender ,you have nothing to adjust into the code.
The chg current is use to detect that the mower is into the station and stop to send the signal.
For the wire avoid 90 deg angle and prefer 45deg small straight of 15 cm and again 45 deg.
The distance with obstacle depends of your platform.
In all case for a first setup it is better to use peg and test many time the back to station until the mower track perfectly all the wire
