External Control Device Setup
Type of connector : D-Sub 9-pin male
No. Pin name
1 No connection
2 RXD (Receive data)
3 TXD (Transmit data)
4 DTR (DTE side ready)
5 GND
6 DSR (DCE side ready)
7 RTS (Ready to send)
8 CTS (Clear to send)
9 No Connection
* 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.

7-Wire Cable Configuration
• The Monitor is available to switch between external
adjustment and remote control adjustment using a
control line.
Note: If the control line is high, the monitor is con-
trolled by the external control device. If the control
line is low, the Monitor is controlled by the Monitor's
remote control.

3-Wire Cable Configuration
• When using a 3-Wire cable configuration there is no
control line. The external control device must put the
Monitor into the "change into remote control adjust-
ment mode" (see page 54). The Monitor will then be
able to be controlled by the remote control. If the
Monitor is turned back on, it will revert back to exter-
nal device control.
