Table 12: Connection of RS232
The RS232, RS485, and I/O interfaces are physically on a 10-pin panel socket. All three
interfaces are not isolated from the router.
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/500 mA. The constant current supplied by the binary input is 3 mA.
