E-EQ-MX1RG-D MX1 Reference Guide
Panning
The MX1 display can be panned around using keypress sequences so the user can view an entire
virtual 640 x 480 pixel screen. Initially, the 20 columns and 20 rows in the top left corner of a
virtual screen are displayed. When the Pan Home key sequence is pressed, the cursor moves to the
top left hand corner of the virtual screen display.
When the initial 20 row x 20 column portion of the screen is displayed:
• and the Pan Right key sequence is pressed, columns 10 through 30 are shown on the
display.
• and the Pan Down key sequence is pressed, rows 5 through 25 are shown on the display.
Panning activation and the pan Factor are configurable in BIOS Setup.
Display Window and Virtual Screen
When the host sends a virtual screen to the MX1, the display window cannot show the whole
virtual screen. The display window can only show parts of the virtual screen.
The virtual screen is a 25 line x 80 column screen that the host sends to the MX1. The display
window is the part of the virtual screen viewed on the MX1. Usually the window is either 10 lines
x 20 columns or 20 lines x 20 columns.
The size of the display window is set by the default font parameter in the BIOS Setup. A default
font size of 8x8 initiates a 20 line x 20 column screen and a default font size of 8x16 initiates a 10
line x 20 column screen display.

Panning and LXE’s Terminal
Emulation Programs
The manual panning key sequence is CTRL-Arrow with no Home function. The spacing between
each pan keypress will be determined by the LXE terminal emulation (TE) program running on
the MX1. LXE TE programs contain active panning (with the exception of LDS and LDS Plus).
