CF located at AMC board below LCD display AMC memory • AMC controller comes with a 2GB Compact Flash card, which is the maximum size usable. This memory will be used to store: • Door configuration • Cardholders • Events
AMC CF card storage capabilities • The table below shows the number of cardholders and events which an AMC can store on the compact flash card when being offline * The APC-AMC2-xxxCF is equipped with a 2 GB CF card!
For 35mm DIN mounting rail • Bosch rail type nr: • AMC RAIL-250 (250mm) • AMC RAIL-400 (400mm)
Mounting Demounting Mounting the AMC • The AMC can be attached on a standard 35 mm DIN mounting rail via a snap-in mechanism. Attach the AMC into the upper edge of the mounting rail, then push down the AMC and snap it onto the rail by pushing it towards the back.
LCD info display • By pushing the info button on the AMC the following data will be rotate on the LCD info display:
Resetting an AMC • It’s rarely possible that an AMC is in an undefined state and doesn’t react properly, e.g. a download fails or was interrupted unexpected. In those cases it might be necessary to reset it. To do so follow this procedure • Insert the provided screwdriver into the hole on the left hand side of the display, as shown in the figure below • Push the reset button for at least three seconds • The AMC will reset and reboots • Now it is possible to reconfigure the AMC2 from the beginning • When online and connected to a host application the download of firmware and configuration data will start automatically after a while With the help of the info LCD display you could check the software version afterwards.
Resetting the network configuration • To Reset the network configurations: • Reset the AMC as described before • Open the upper case of the AMC2 as described before • Set all six DIL switches of the RS-485 selector to ON • Press the tamper switch on the upper left side of the board • The AMC2 will now have the following network configuration: • DHCP = 0 • IP = 127.0.0.1
