1.3.4 Serial interfaces

Use

External units can be connected to the AC31 system via

the serial interfaces. The interfaces are independent of

each other. They can be managed via freely definable

protocols.

Scope of functions

The four serial interfaces can be configured independently

of each other in the following scope of functions:

• Data format 7 or 8 bits

• Even, odd or no parity

• Discrete baud rates

from 300 Bd to 19200 Bd for COM3 and COM 4 and

from 300 Bd to 9600 Bd for COM5 and COM6

• Automatic processing of the SW handshake

(XON/XOFF)

• Automatic processing of the HW handshake

(RTS/CTS)

• Error detection

(parity, framing, overrun, break)

Serial interfaces COM3, COM4

Interface standard

– EIA RS-232 or

– EIA RS-422 or

– EIA RS-485

Both interfaces can be run independently of each other in

one of the interface standards each. Selection is by choos-

ing the corresponding interface signals.

Modes

– Programming and test mode

– Application mode

COM3 can be used as a programming and test interface.

This mode is set at pin 6 of the interface connector by the

signal status.

Electrical isolation

Both interfaces are electrically isolated.

Connection

Connection is via a 15-pole D-SUB connector (female).
