IP Substation - Additional DAK keys
From Zenitel Wiki
The IP substation board supports input for digits 0 - 9, 10 DAK-keys, as well as M-key and C-key. The inputs are available on soldering pads on the substation PCB.
Inputs for DAK-keys, M- and C-key
DAK 1: N115 + N112 DAK 2: N115 + N113 DAK 3: N115 + N114 DAK 4: N105 + N110 DAK 5: N105 + N111 DAK 6: N105 + N112 DAK 7: N105 + N113 DAK 8: N105 + N114 DAK 9: N105 + N115 DAK 10: N106 + N110 ------------------- M-key: N115 + N111 C-key: N115 + N110
If more than 10 DAK keys are needed, it is possible to use the digit keys as DAK keys. This needs to be enabled by the flag "Digit Key is DAK" in the Users & Stations > Station Type menu in AlphaPro. The regular DAK keys are then moved to DAK 11 - 20.
Inputs for digit keys
Digit 0: N111 + N110 Digit 1: N112 + N110 Digit 2: N112 + N111 Digit 3: N113 + N110 Digit 4: N113 + N111 Digit 5: N113 + N112 Digit 6: N114 + N110 Digit 7: N114 + N111 Digit 8: N114 + N112 Digit 9: N114 + N111
The keyboard matrix
KEY0 = N110 KEY1 = N111 KEY2 = N112 KEY3 = N113 KEY4 = N114 KEY5 = N115 KEY6 = N105 KEY7 = N106 KEY8 = N107
