OPTIMAL SETTINGS FOR LCD / DLP / D-ILA / PLASMA DISPLAYS

The following output sync settings provide maximum signal preservation and are recommended
for the best image quality with LCD, DLP, D-ILA and Plasma Display devices. Depending on
the design of the display device’s sync processing circuitry, you may be able to set the horizontal
position control (dipswitch #1) to the enabled position. However, experimentation with your
display device is the best way to determine whether you can achieve a stable image with the
horizontal position enabled. Many LCD displays include a fine phase control, which can be
adjusted to optimize picture quality.

Dipswitches ON:

1 & 2

Signal Format:

Red / Green / Blue / Horizontal and Vertical Sync

Horizontal Position Control: Disabled
H & V Sync Polarity:

Mirror Input Polarities

REMOTE CONTROL OPERATION

The IN2118 can be raised and lowered by pressing down on the top surface, or via remote control.
The remote port is a 4-pin captive screw terminal on the connector plate that allows the interface to
be controlled by any device that is capable of providing a latching contact closure, or by an RS-232
control device (when used with an optional IN6901 / IN6902 RS-232 to contact closure converter).

Contact Closure Control: The interface can be raised or
lowered via the remote port by providing a latching contact
closure between pin 1 and pin 2 on the remote jack.
Opening / closing the contact closure causes the unit to
ascend / descend. The manual control (pressing down on the
top surface) and the contact closure switch work
independently. Therefore, an open or closed status between
pins 1 & 2 on the remote port could select either the raising
or lowering of the interface, depending on the current
position of the unit.

Status: The remote connector status pins (3 & 4) can be used to provide feedback to a control
system to indicate whether the IN2118 is in the raised or lowered position. The status pin will be
open or closed depending on the current position:

Closed: Unit is in the raised position
Open: Unit is in the lowered position

CONTACT CLOSURE DEVICES

Any device capable of providing a latching contact closure may be used to control the IN2118.
Several contact closure type devices are available:

IN6901 / IN6902 RS-232 to Contact Closure Converter - allows the IN2118 and other

INLINE devices with contact closure control ports to be regulated by RS-232 sources.

Control System - many control systems are capable of providing contact closures.
