Preferably the cable should not be more then 100 metres (330 ft) long for Wiegand interface, or 10

Positioning the reader and labels
The ELC1 reader is supplied with a spacer and a number of labels to suit different mounting locations.

position with the cable running through one of the four Cable Access Points .
