The unit is intended to be the controller for an access control system using iButton® as the entry mechanism. The PCB is housed in a compact plastic box and can be placed at a distance from the iButton® reader. The unit caters for up to 223 keys and the keys are programmed at the unit without the need for a PC. The Unit comes pre-programmed with 2 Master/Administration Keys and 3 Client/User Keys with additional User Keys available at time of order.
