Using RAMM offloads many of the operations performed by the AXxess202/NS computer and provides state of the art distributed processing performance and system optimization.The RAMM communicates to the BLP processors and Input Modules through an RS-485data bus and it communicates with the AXxess 202/NS host through your choice of a communicationsnetwork consisting of RS-232/RS-485, Ethernet, dial-up modem, and direct Fiber Optics connectivityoptions. The RAMM is provided with a 16VAC/20VA transformer for power* and it canmount on a second DIN rail in an existing BLP-200 enclosure. You may optionally estimate a separatelocking enclosure if you prefer. Separately estimate batteries for back up operation.Ethernet: If you will be using a local or wide area network for your communications, estimate theRAMM, Ethernet model. This model comes equipped with on-board 10/100 Ethernet interface. Note:Remember when planning your network that RAMMs require a static IP address.Ethernet/FiberIf you will be using a local or wide area network for your communications to RAMM and will be using a fiberoptic connection to BLP Processors, estimate the RAMM, Ethernet, Fiber model. This model comes equippedwith on-board Ethernet interface. Note: Remember when planning your network that RAMMs require a staticIP address.Fiber Optics: If you require direct Fiber Optics connectivity, select the RAMM, F/O that providesthe Fiber option module on-board the RAMM.Elevator Control: The RAMM supports up to (5) elevator readers with a maximum of 1000 AccessLevel combinations. Using the RAMM provides significantly faster and more reliable elevator control operationthan when relying solely on BLPs and the computer to make the selective floor decisions.Encryption: The RAMM must be used if you require encryption on your system. 128 bit AES dataencryption is available for all forms of RAMM communication, i.e. Ethernet, RS-232/RS-485, etc.Dial-up Applications: The U.S. Robotics Sportster 56K modem is the device that has beenqualified by MAXxess to support dial-up in either RAMM or BLP dial-up applications.(*Note: For a more complete discussion of optimal device powering for MAXxess systems, please refer toMAXxess Application Note #20. Application Notes may be found in the Support Section of the MAXxess website.)22
