EHX System Configuration for ICS-22 Panels
The Eclipse Configuration System (EHX) software does not directly support the ICS-22 speaker panel. To configure   an ICS-22 panel, the port is configured to drive an ICS-1008 panel with 14 keys (7 pairs of buttons). The two ICS-22 selectors are mapped onto the ICS-1008 keys starting from the left. Only the leftmost two pairs of keys on the  ICS-1008 can be used to program the ICS-22; any other keys on the ICS-1008 will have no effect.
There must be a corresponding listen key on the top row to the talk key on the bottom row of the ICS-1008 configuration for the ICS-22 panel to work correctly. If a talk key only is configured on the ICS-1008 in EHX the Talk key on the ICS-22 will not latch.
Note that the panel signalling and control protocol used by the Eclipse matrix differs from the Matrix Plus 3. So, the operation of these panels with an Eclipse matrix may be slightly different to their operation with a Matrix Plus 3.
