5.8.2 Serial Interfaces and I/O Port

The RS232 and RS485 serial interfaces together with the I/O interface are physically con-
nected to the 10-pin panel socket. All three interfaces are not isolated from the router. The
pinout of this conector is described in the tables below.
The I/O user interface is designed for binary input processing and binary output control.
By default, the binary output is open, so it is not grounded. The maximum binary output load
is 36 V at 500 mA. The constant current supplied by the binary input is 3 mA.
