2.3.6 External OSD-Keyboard Interface
This connector is for an external passive keyboard which has exactly same functionality as the
buttons on the front of the panel, used to control the OSD (on screen display) (see section 3.1, page
27).
An external keyboard allows operation of the monitor when the front side keyboard is not accessible
or is absent. Cable length for this external keyboard should not exceed 7 meters.
The keys of the external keyboard pull the signal to ground (see following sketch).

2.4 Electrical Installation
Before connecting the Raptor SQ2801 to main power, ensure that all connectors for video signals and
serial interfaces are plugged in properly and securely.
After that, the monitor may be connected to main power and switched on by turning ON the main
power switch on the rear of the unit (see Fig. 12, page 21).
NOTE
By default, automatic source scan is disabled and the DVI-1video input interface is activated.
A different video input interface can be selected via the OSD menu (see 3.2, page 28) or the
serial interfaces.
