MXSSU Product Information


The MXSSU Serial Splitter Unit is designed to allow a single serial connection to be made to multiple base station radios. Although it does not provide the flow control to and from the base stations, it does ensure that all connected equipment operates with correct RS232 levels and impedances. The rear panel provides access to all connectors and the front panel provides 10 LED indicators for the SSU status and an additional RS232 port on the front to allow temporary serial access to networked base stations.
