You can connect a PC or terminal to the VR 2300 via the serial interface and configure the
VR 2300 through this connection. For this, you need a crossed RS 232 connection cable
(null modem cable) that provides the connections RxD, TxD and GND, as well as RTS and
CTS (see figure 7.1).

If the VR 2300 is connected to a connector unit MA 2 or MA 2 L, you can use the 9 pin sub-
D service connector in the connector unit or connect the interface cable directly to the termi-
nals of the connector unit (see figure 7.2).
