DESCRIPTION OF DA1912SX
4
4.1 INPUT TERMINATION SWITCH
The Input Termination Switch is normally set to
the ON position and provides 75 Ohms
termination for the Red, Green, and Blue
channels. By setting this switch in the OFF
position and using BNC "T" connectors, the input
may be looped to another
DA1912SX
, to a local
monitor, or to another piece of equipment, if
desired.
4.2 VIDEO LEVEL SWITCH
The Video Level Switch can be set to either the
standard 0.7V output or to 1.0V output. When the
switch is set in the 1.0V output position, this
provides approximately a 35% increase in video
signal level. This can be used in installations
where cable runs exceed 100 feet. It is not
recommended that this switch be set in the 1.0V
position for shorter cable lengths as the increased
level may reduce the life of CRT displays if they
are overdriven.
4.3 SYNC LEVEL SWITCH
The Sync Level Switch allows the
DA1912SX
to
output a Sync Level of either 2V p-p or 4V p-p.
This switch should normally be set in the 4V
position. Some older display equipment may
require a sync level of 2V in which case this switch
may be used, but this would be rare.
4.4 POWER
The
DA1912SX
requires the use of a 9V 500mA
power supply, which is included with the unit. A
variety of different power supplies are available for
international use.
4.5 MOUNTING THE DA1912SX
To mount the
DA1912SX
, Altinex offers "L" shape
mini-brackets, the
DA1295SX
, which provides
wings on either side of the unit, allowing it to be
installed on a rack plate, furniture, or a wall.
