Management Asynchronous Ports
J24 and J25 are two RS-232 communication ports that allow two optional management systems to be connected
to the HiGain system. Consult the HMU-319 List 5B technical practice for use of the two communication parts.
Multishelf Network Connector
One BNC connector on the backplane allows several shelves to be chained together into an integrated network
through a 10BASE-2 (IEEE 802.3) Ethernet LAN. The connector is J26.
Management Network Port
An RJ-45 (J34) is used to connect the management card to a 10BASE-T Ethernet management network.
