dDESCRIPTION OF DA1907SX 4
4.1 INPUT
The Computer Input connector of DA1907SX is
connected to the Video output of the laptop or
desktop computer. The DA1907SX is provided
with a 3 foot Male to Male VGA Input cable
(ALTINEX part # CB3703MR). A longer input
cable may be used but lengths over 15 feet are
generally not recommended to preserve the
signal quality. If desired, the HD-15 input can be
easily adapted to 5-BNC connector output with a
proper cable.
Often, laptop computers will require a toggle
command, which will instruct the laptop to output
to the internal display as well as to the external
video port simultaneously. You may need to
check the user’s manual for your laptop
computer to determine this command.
