Suggested Cable Colours (Cat5)

RFID / Wiegand Reader

Suggested colouring when using Cat5 cable for a Wiegand reader, including optional wiring (not all readers support all features):

Function Reader Wire Cat5 Colour Required
+12V Power Red Brown ✓
0V Ground Black Blue ✓
Wiegand 0 Green Green ✓
Wiegand 1 White Green/White ✓
Buzzer Yellow Brown/White ✗
LED Control Blue Blue/White ✗
Bell A Orange Orange ✗
Bell B Brown Orange/White ✗

Note that the Buzzer and LED colours were originally reversed (initial documentation commit was made in 2017) compared with their current values above. The suggested colours were updated in 2026 to use Brown/White for the yellow buzzer wire and Blue/White for the blue LED wire as these are closer to the reader cable colours. It is therefore recommended to double-check the colours when wiring the connector (and if the buzzer sounds when the LED should light, or vice versa, then just swap these two wires over)

Keypad

Suggested colouring for Farnell 1130805 (ECO.12150.06.SP) keypad. (Brown core is spare).

Pin Row/Col Name Cat5 Colour
5 COL 3 D Orange/White
6 COL 2 E Orange
7 COL 1 F Green/White
8 ROW # G Green
9 ROW 7 H Blue/White
10 ROW 4 J Blue
11 ROW 1 K Brown/White
