4.5 Serial Interface
The C11/G2 provides a serial interface which is used to connect a
communication device for transmitting data or a PC for controlling the
C11/G2. The serial interface corresponds to the V.24/RS-232 standard
and supports the following features:
•
Transmission speed: 300 – 921.600 bps (asynchronous)
•
Character representation: 7/8 bit, no/even/odd/mark/space parity, 1 or 2 stop bits
•
Hardware flow control with RTS/CTS
The C11/G2 can be used in DTE or DCE mode. This requires a special
setting in the firmware. The selection of the appropriate D-SUB socket is made by
jumper J2.20.
