The following illistrations show the port connections on the 215U-2.
Power Supply Wiring
The ground (GND) and “SUP -” terminals are connected internally to the ground (Earth) terminal.
Connect the screw terminal on the end plate to ground (Earth) for surge protection.
Expansion I/O Power and RS485 serial connection
An on-board RS-485 terminating resistor provides line termination for long runs.
Only enable terminating resistor on the last device connected on the RS-485 cable.
