The eRAM communicatesto the BLP processors and Input Modules through an RS-485 data bus (eRAM includes twoRS-485 ports) and it communicates with the AXxess 202/NS host through Ethernet connectivity at atrue 100 mbps speed. The eRAM can mount on a second DIN rail in an existing BLP-206 enclosure.Optionally estimate a separate locking enclosure if desired. (Please note: DIN rail is not includedwith the eRAM.) Separately estimate batteries for back up operation. eRAM requirtes a 12VDC regulatedpower supply such as the BUPS (not included).Ethernet: eRAM is an IP-centric device. It features a 10/100 auto-sensing IP port. Note: Remember eRAMrequires a static IP address.Please refer to the eRAM data sheet and manual for the features and limitationsElevator Control: The eRAM supports up to (5) elevator readers. Using the eRAM provides significantlyfaster and more reliable elevator control operation than when relying solely on BLPs and the computer to makethe selective floor decisions.Encryption: The eRAM must be used if you require encryption on your system. 128 bit AES data encryption.(*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.)20
