TxNET module
The TxNET module is simply a passive board that acts as an interface between the wiring on
the inside of the amplifier enclosure and connections on the outside of the enclosure. There is
a high power version for systems that have more than one amplifier enclosure and a low power
version, which does not have external enclosures aside from the modulator. The DB-25
connector for the remote port (J602) is attached to the TxNET module. The signals travelling
through this port are connected to the Coupler Conditioning module through J601 and J603.
The TxNET module also includes up to three straight through RJ45 connection pairs: J604 to
J605, J606 to J607, and J608 to J609. These connections are only used on systems with
multiple enclosures, to pass control signals between enclosures; otherwise a low power TxNET
is used.
