Use a null modem cable.
Wire the 7-Wire cable so that each pair of data lines cross between the two devices. These data line pairs
are RXD (Receive data) and TXD (Transmit data), DTR (DTE side ready) and DSR (DCE side ready), and
RTS (Ready to send) and CTS (Clear to send).
When using the 3-Wire cable connected to RXD, TXD and GND; Pin No. 4 (DTR) and Pin No. 6 (DSR)
must be connected to the monitor. (The cable must be disconnected from the Monitor to be able to use the
remote control and Monitor front panel controls.)

With the RS-232 input connected, the Monitor cannot be controlled by both an external control device and
the remote control at the same time. The Monitor can only be controlled by either the remote control or the
external control device.
