2.3.5.8.3.5 Terminating resistor
A terminating resistor is integrated for each COM on the interface option; they are located to the left and right of
the IFx connector. The terminating resistor is enabled or disabled using a switch. LED status indicators L2 and L3
indicate whether the terminating resistor is enabled or disabled.
On The terminating resistor is switched on.
Off The terminating resistor is switched off.
2.3.5.8.3.6 Shielding
The shields for the cables connected to the 10-pin female connector can be connected to the screw connection for
cable shields (see "Device interfaces - Overview" on page
of the system unit's interface cover.
2.3.5.8.3.7 LED status indicators L2, L3
LEDs are integrated in the interface option; they are located above the terminating resistor.
