GXP2200EXT MPK Display
Each GXP2200EXT board can have 2 pages. It allows user to display up to 40 MPKs. Users can use LEFT
or RIGHT key to switch between pages. Page 1 displays MPKs from 1 to 20; page 2 displays MPKs from
21 to 40.
There are two types of page on the GXP2200EXT MPK display:
Type 1: Basic MPK Info.
In this type, all the configured MPKs will display in the configured order.
Type 2: Active MPK Info.
In this type, only the active MPKs (blinking in red) will display.
Note:
The MPK is considered as "active" if the MPK LED is blinking in red.
After the GXP2200EXT boots up, the Basic MPK Info page will be displayed by default. If any of the MPK
status is changed to active (blinking in red), the Active MPK Info page will be automatically opened.
