The P1 port, which is the RJ-11 connection, has the serial protocol where standard IEC-62056-21 is used.
Schematische voorstelling P1 poort (ESMRv5.0 P1)

Note: Does not include the Dutch Smart Meter
The P1 port is a 6p6c socket, commonly referred to as RJ12. The RJ11/RJ12 plug is the one we have known for years as the telephone plug. You can go with an RJ11 plug that has only the 4 middle pins connected, but your best option is to use an RJ12 connection with all 6 wires connected. That way you can optionally use the power output from the P1 port to power the reading device. The 6 pins of the P1 port are wired as shown in the table below.
 
Specifications:
1 +5V                 Power supply line (250mA)
2 Request         Data request (high)
3 Data GND Ground for the data signal
4 N.C.                 Not Connected
5 Data                 Serial data output signal
6 Power GND Power ground
Pin 4 is not used.

Pin 1 and 6 provide power that can be used by a connected device. According to the DSMR 5.0 standard, this output is capable of providing 250mA at 5V. This power output was not available pre-DSMR 4. But the 4.x.x standard does not give details of its maximum load, only the DSMR 5.0 standards description.
 
Pin 5 and 3 are the serial output pins and provides a logical 1 with an output voltage of less than 1V, and a logical 0 with an output voltage of more than 4V. This is commonly referred to as TTL Serial. The Landis meter has an open collector output (pin 5), meaning that we need to add a pull-up resistor of 1-2k to allow the data output to switch between these states. Note that the output is inverted, so we'll have to invert the signal by software or hardware. The baudrate is 115200 bps with 8 bits, no parity and 1 stop bit (8N1). Up to DSMR 3.x the rate was only 9600 baud.
 
Pin 2 can be used to control the dataflow from the meter. Make this pin high (>4V) to have the meter send it's data on the data output pin. You can either make this permanently high, resulting in a constant flow of meter data every 10 seconds, or only when you want to request data. To stop receiving data, an OSM needs to drop the “Data Request” line - that is, set it to “high impedance”. Data transfer will stop immediately in such case. For backward compatibility reason, no OSM is allowed to set “Data Request” line low (set it to GND or 0V).
