Fig. 15: Connection of two MPPT 6000-M devices via the master connection is not possible
The bus cable pin assignments are specified in the following table.
The StecaLink master connection of the MPPT 6000-M is galvanically isolated from the power unit.

6.7 UART/RS-232 interface connection (MPPT 6000-M only)
NOTICE!
The UART connection on the unit provides a serial interface with RS-232-compatible signal
levels. See
Ä
Chapter 12 ‘Technical data’ on page 124.
The interface can be used for sending data from the device to a PC.
Data transmission from a PC to the device is not possible.
A 3-pin plug with screw terminals for constructing an individual cable is supplied with the
device.
TxD, RxD and GND (signal ground) are present at the 3-pin connection, see printed label.
The serial interface is galvanically isolated from the power unit connections.
The interface can be switched on and off.
The data output is fixed by the device and cannot be changed.
Data is output at 1 minute intervals.
For information on the data content of the serial output, see
Ä
Chapter 12.3 ‘UART/
RS-232 interface protocol (MPPT 6000-M only)’ on page 142.
After activating the UART interface it can take up to one minute before the first data is
output.
1. Connect an external receiving device to the UART connection.
2.
For information on activating data output at the MPPT 6000-M, see

Chapter 8.13 ‘UART/
RS-232 interface (MPPT 6000-M only)’ on page 100.
