● Description of keypad interface
Keypad connection interface CN5 on the control board adopts 8PIN drop-out lines with fool-proof ports. Users can
customize extended keypad cable according to actual needs. But the keypad extension cable does not exceed 15 m,
because when it exceeds 15 m, normal work cannot be guaranteed.
Fig. 2-40 Keypad interface CN5 on control board
The cables connecting keypad and control board use standard super-five-class network cable. RJ-45 Interface uses
through-line method, namely both sides are connected according to EIA/TIA568B standard. You can make the cable
by yourself if you need.
 Tips
1. Both sides of keypad cable should be connected refer to Table 2-9. Otherwise, the cable couldn't work properly
or even the keypad would be damaged.
2. When the keypad extension cable is longer than 1 m, which must use shielded twist-pair network cable, RJ-45
interfaces of both sides of the cable should use crystal with shielded metal shell, connect shielded metal shell to
shielded layer. Otherwise, it is likely to cause error action because of disturbance.
3. Be sure the extension cable of the keypad is no longer than 15 meters, otherwise it wouldn't work properly.
