Keymatrix Inputs

The PHCC system allows you to connect up to 1024 boolean (on/off) inputs. This should be sufficient for most simbuilder's needs (but no all as I've heard :-)

This allows you to connect for example:

MCP/Autopilot panel
MIP (main instrument panel)
CDUs
pedestal
overhead
circuit breakers
...

These inputs are arranged in a matrix. The matrix consists of eight columns and 128 rows. The rows are organized in 16 groups of 8 rows. This translates into 16 keymatrix daughterboards with each 64 inputs (arranged as an 8x8 matrix).

Available or planned PHCC Keymatrix Input Daughterboards

KEY64D_PH
KEY64D_SC35
KEY64_251 (Strictly speaking NOT in matrix organization. Has one common wire for each input. So, there are 64+1 wires per board.)
