Interface Selector Shunts

Figure 4 (see page 12) shows the interface selector shunts and header. These configure the

Bridge’s serial interface for RS-232, RS-422, or RS-485, as follows:

RS-485 w/

Termination

RS-232 Power Pin 9,

Cable Sense

RS-232

Cable Sense

RS-422 w/

Termination

Figure 5. Interface Selector Shunts

To allow reliable connection through an RS-232, RS-422, or RS-485 interface, set these shunts

appropriately before using the Bridge with your application.

Note:

The interface type selected by the interface selector shunts must match the

Interface Type setting on the Serial Interface Configuration page of the ACC

interface (see page 35). Otherwise, this mismatch prevents data from being

exchanged.
