1GUN / 3 GUNS BRIGHTNESS

This function allows to select (via OSD menu) between Low Brigtness Mode (even better picture sharpness and reduced eye strain) and High Brightness Mode (full brightness).

WARNING: This function is available only if “1-BNC” input is selected since it has no much sence with color video cards.

MAP 201 - Calibration Package (optional)

Specifically designed for the Triple Gun monochrome monitor series, this package con- sists of a calibration software and an high sensitivity light probe sensor.

The calibration package allows precise calibration of: brightness uniformity across the entire area, black level and white level, moreover it allows the user to correct the beam convergence from edge to edge for optimum display sharpness and accuracy.

ORBITING

The MGD 203/MGD 403 monitor includes a circuit specifically developed to increase the Cathode Ray Tube phosphors life-time by slightly moving, on a circular orbit, the entire dis- played image.

DAISY CHAIN INTERFACE

The two 9-pin DSUB (male and female) connectors are parallel-wired RS485-like Multi- Point Serial Interface to allow the connection of up to 15 units in daisy chained configura- tion, each one having unique address in the range from 1 to 15.

The maximum total cable lenght between monitors is 15 m.

If Daisy Chain Mode is ENABLED the RS232, KEYBOARD and ABC controls are trasmit- ted to all the other monitors and at the same time executed inside the monitors.

(see specific chapter for details)

AUTOMATIC BRIGHTNESS CONTROL

The ABC feauture automatically adapts the contrast/brightness level to the ambient light (measured with a special sensor).

The ABC function is selectable in one of the following three modes:

Active control range : 10 - 1000 lux ambient on the photo-sensor

ABC - FULL	Adjustable Reduction Effect via OSD (20% - 100%)
ABC - REDUCTION	Derived from ABC - FULL
ABC - OFF	No reduction (100%)

In case of daisy chain connection only one unit can be allowed to be “ABC master” (fly- ing master concept). See also pages 18 and 25 of this user manual.

SHOW CONFIGURATION

Via OSD it is possible to display the monitor unit information:

firmware release, total working hours (to keep track of the real usage of the monitor), active video mode, horizontal and vertical frequencies.
