max 50 m
If the terminal connection distance is over 50 m, but no longer than 200 m, 3 pairs of braided wires should be
used, enclosed in a shielding having a cross-section of at least 0.5 sq.mm and T-switches (Carel code
TCONN6J000), as shown in the figure.
The pLAN network communicates through standard RS485 serial with baud-rate of 65.2 kbit/s. It uses the
Carel Multimaster protocol and can have a maximum extension of 500 m using T-switches for remoting.
