From the very first remote radio replacement enjoy market leading Aprisa radio features in terms of speed, coverage, security, IP, and advanced management options . Your network is no longer limited to performing in a crippled backward compatibility mode . THE MMS BENEFITS Benefit now by migrating your network smoothly with the minimum of cost and downtime, using existing frequencies and antennas . Leverage your maintenance budget to get a real performance and feature set upgrade . Legacy vendor backward compatibility solutions lead to a staged upgrade program, only achieving promised improvements and investment return at the end of the project at which point the network will be behind today’s next generation Aprisa SR+ performance and feature set . Think forwards not backwards! MMS SYSTEM COMPONENTS AND CONFIGURATION The MMS system comprises of two main components, the standard Aprisa SR+ protected or non - protected master station and the new migration switch, a fully redundant RF switch . The MMS is installed side - by - side with the legacy master station . The new Aprisa SR+ network uses the same frequencies and antenna as the existing radio network . The migration switch connects to the RF antenna and shares this with the legacy master or the Aprisa SR+ master station as required by the remotes . The migration switch is managed by the advanced logic in the Aprisa SR+ protected master station . All SCADA traffic is directed through the Aprisa SR+ master, which passes traffic destined for the legacy network to the legacy base station in addition to setting the migration switch for the antenna .

Version 1 . 0 . 0 MMS OPERATING CONFIGURATIONS The Aprisa SR+ MMS supports standard legacy radio networks, with repeater based network support scheduled for the near future . The MMS supports integration with MDS ™ x 790 / x 710 networks with the master station operating in non - continuously keyed switched carrier mode . The legacy network traffic must be serial utilizing a standard poll/response protocol . Support is protocol specific . Multiple protocols including DNP 3 , Modbus and a range of others are supported with the initial release, additional protocols will be released on customer request . The MMS supports Aprisa SR+ protected or non - protected master stations . Future support for other products and operating modes is in development . OPERATIONAL OVERVIEW The Aprisa SR+ inspects the serial SCADA traffic packets to determine the destination address . Each packet is mapped to either the legacy or the Aprisa SR+ network based on SCADA address learning, utilizing the address / destination ID field of the SCADA protocol . Initially all SCADA protocol addresses will be assumed to exist on the legacy network . If a transaction to a remote address times out or there is no response the packet can be resent on the Aprisa SR+ network . If an address is detected as working on the Aprisa SR+ network, it is added to the address map for the Aprisa SR+ network . This allows you to progressively switch out legacy remote radios without any configuration of the MMS address map or host controller . The address map can also be manual defined as an option . When migration of all remotes is complete the legacy master and the migration switch component of the MMS can be removed resulting in a standard Aprisa SR+ master station installation . REDUNDANCY The migration switch contains a fully redundant RF switch, operating as a part of the MMS . Any hardware failure in the migration switch (or master station) results in a switchover and the MMS will continue to operate switching traffic between the legacy and Aprisa SR+ networks . The MMS provides full protection to the master station site . CONNECTION TO SCADA MASTER / HOST CONTROLLER For best performance the existing serial connection to the host controller should be set to the maximum bit rate ( 115 kbit /s) or replaced by an Ethernet connection, if available, to maximize the performance of the network as remote upgrades progress . These higher speeds also work to reduce serialization delays in the legacy master station connection . OPERATING TEMPERATURE With the superior thermal design common across all Aprisa products the MMS operates across the full temperature range without de - rating or the need for fans . POWER SUPPLY The Aprisa SR+ MMS supports redundant power supply inputs . Power supply options of 12 VDC and 48 VDC are available . MANAGEMENT Configuration and management of the Aprisa SR+ protected s tation (and MMS) is done via the 4 RF SuperVisor web - based browser application . With its comprehensive, easy to use graphical user interface SuperVisor enhances network configuration and set up, improves fault identification and isolation, and increases asset visibility .
