Chapter 2. SPECIFICATIONS
Use standard, off-the-shelf coaxial cabling to connect external equipment (e.g., a modem), to
each internal converter module. Use coaxial cabling to connect the output for each module to RF
equipment either at the same location or at the antenna location. When configured with the
redundancy option, the system may contain two diode “OR-ed” internal power supplies for
increased reliability.
See Chapter 2. SPECIFICATIONS for component specifications.
