22. Async Communication Debug Monitor and Diagnostic LEDs The microprocessor communicates with the DAS processor using the second serial communication controller SCC of the communication processor module CPM This asynchronous communication channel operates at TTL levels and is optically isolated within the DAS The microprocessor provides an Ethernet controller which is implemented on SCC1 in order to benefit from the additional buffer descriptors compared to SCC2 Ethernet packets are stored in SRAM buffers and are transmitted and received by the 10BASE T transceiver The Ethernet clocks are generated from a 20 MHz crystal oscillator circuit and the transceiver The transceiver also provides a visual indication in the form of four LEDS to identify packet transmit receive collision and link integrity The status of received data is indicated by the link integrity signal which is used by the microprocessor to determine if the monitor is connected to the Unity Network An isolation transformer provides basic insulation to the twisted pair interface required to meet the ANSI IEEE 802 3 standard Ethernet Isolation is required because during transport the power cord with the ground conductor is not available to provide a path for a fault condition An 8 pin RJ 45 connector containing two isolated differential pairs is provided to connect the monitor to a network hub NOTE Power is not provided in the twisted pair interface as in the at
