HCS-DEC-4 --------------------------------------------------------------------------------------------------------------------------------------------------- User Manual 65PR000977 The decoder board HCS-DEC-4 is a 4 channels central unit which can be matched with any HCS Keeloq encoded keyfob programmed with Aurel manufacturer code. It allows to be supplied either at 12Vdc or 24Vac selectable by means of a jumper before switching on. Embedded relays can work indistinctly in monostable or bistable mode according to the need. How it works Before switching on the board, set the jumper according to the wanted voltage supply: Jumper closed = 10-12Vdc Jumper open = 24-26Vac As soon as the board is supplied, the led switches on for few instants and then switches off again, that means the board has been correctly supplied. From now on any HCS Keeloq encoded keyfob programmed with Aurel manufacturer code can be auto learnt following the standard procedure. Auto learning procedure In order to start the auto learning phase press shortly the auto learning button near the led. Led starts blinking quickly for 10 seconds within user must emit a valid code by pressing any button. When a valid code is received, led switchs from blinking to steadily on for few instants and then switches off. By pressing the 4 buttons now the relay monostable output will be switched. Receiver can store up to 10 different transmitters. Note: the auto learning of a 2,3 or 4 channels keyfob can be performed by pressing whatever button as the central unit handles the data frame to allocate each channel as described hereunder: Le caratteristiche tecniche possono subire variazioni senza preavviso.

Now led starts blinking quickly for 10 seconds before this time expires, press the button again shortly and led will switch on steadily. Now within 10 seconds press the button of the channel you want to make bistable. Done it, the led blinks three times to show the operation was executed correctly. Repeating the operation on the same channel the led would blink twice to show the return to monostable mode. N.B. The described procedure can be executed only whether at least one keyfob is stored in memory. In case more keyfobs have been stored the output is activable by all keyfobs stored indistinctly and its valid for all. Erasing memory In order to erase all the keyfobs stored in memory press shortly the auto learning button until it starts blinking. Now press it again and hold it down for 5 seconds until the led switches off. Then release it and verify that led blinks 5 times to indicate the memory has been erased. N.B. By erasing the memory all setting of bistable channels are reset. Le caratteristiche tecniche possono subire variazioni senza preavviso.
