Figure 6 Memory Section Block Diagram
2.6 NET section
The Ethernet interface controller is basically the heart of the NET section. The interface
controller communicates with the CPU section through the CPU bus. The section also contains
a 4k SRAM memory.
The network interface controller transmits data packets to the Datex-Ohmeda Network and
receives data packets from the network through the 10BASE-T transformer. The transformer
filters and transforms the data and also provides the isolation.
The Ethernet status LEDs indicate the status of the network communication. The status LEDs
are controlled by the network controller. The LEDs are located on the Central Processing Board.
The PLD interfaces the coding element. The coding element contains information on the
monitor location. The network address and the monitor location information are transmitted to
the CPU section directly through the CPU bus.
