DLV 1280 User's Manual
Figure 2-23. RS-232 Serial Ports
NOTES: 1) DLV 1280 serial connections require a 9-pin D connector. Refer to
Appendix D for complete cable wiring requirements 2) The "
RS-232 OUT
" port
is provided for networking applications only — see "If using multiple
projectors”, below.
You may wish to use a computer rather than a keypad for controlling the
projector and for performing other special functions. Connect an RS-232 serial
communication cable between the computer and the projector serial port labeled
"
RS-232 IN
" (Figure 2-24). Then set the baud rate to match that of the computer.
Changing the baud rate is described in 3.7, Adjusting and Checking System
Parameters.

Note: PC software is required for computer control. Contact your dealer or
Electrohome for details.
You may wish to use one or more external switchers, such as the Marquee
Switcher, in order to significantly increase the number of sources you can use.
Connect an RS-232 serial communication cable between the switcher and the
projector serial port labeled "
RS-232 SWITCHER
" (Figure 2-25). This port is
permanently set at 9600 baud.
