Note: The IN2085 and IN3012 will also operate with RGsB signals (sync on green) and RsGsBs signals

(sync on all). In these situations, only use the red, green, and blue channels (i.e.: leave the sync channel

open). The red, green and blue channels can also be used to amplify or split composite NTSC video

signals.

JUMPER REFERENCE LIST

INLINE provides 7 internal jumpers which are used to customize the IN2085/3012 for specific needs.

While the jumpers need not be touched for most normal installations, this section describes how to change

the jumper settings for unique applications.

Input Impedance

J2, J4, and J6 are used to unterminate or terminate the red green and blue inputs to 75 Ohms. Open is

unterminated and closed is terminated to 75 Ohms. Factory setting is closed (75 ohm termination).

J7 is used to unterminate or terminate the sync input to 75 Ohms. Open is unterminated and closed is

terminated to 75 Ohms. Factory setting is open (unterminated / high impedance).

AC/DC coupling

J1, J3, and J5 are used to set the red, green and blue channels for AC or DC coupling. Closed is DC

coupled and open is AC coupled. Factory setting is open (AC coupled).

See the drawing below for jumper locations.

Use the following steps to modify the jumper settings.

1. Unplug the power from the unit.

2. Remove the screw on the bottom of the unit and slide the top cover off.

3. Gently position jumpers as required for your application.

4. Replace top cover and tighten screw.
