3 TxRx- RS485 B (-) Input/Output
4 TxRx+ RS485 A (+) Input/Output
5 TxRx- RS485 B (-) Input/Output
6 TxRx+ RS485 A (+) Input/Output
7 +12V EXT External power supply +10,8 ÷ +15,6V
8 +12V EXT External power supply +10,8 ÷ +15,6V
ATTENTION! External supply is for converter RS485!
The converter must have external power supply because of galvanic separated.
