7.1.3 Power Monitoring
The 9100 power monitoring circuit constantly checks the operating condition of the
internal power supply. If the power goes out of range, all ports are turned off, and all
LEDs will be in Fast blink mode.
7.2 Diagnostics and Status Reporting
The 9100 PowerBaseT console port consists of a UART port on the microcontroller,
RS232 transceiver (U7) and a DB9 connector. Detailed information and the DB9
connector pinout is given on page B-4. The DB9 connector is used for the following
functions:
• Report Status Using a PC and HyperTerminal.
• Programming/Download Supports code updates by Field Service personnel.
The microcontroller is required to provide the following functions:
• Maintain port status Port off, Port on, fault
• Maintain port control Port enabled, Port disabled
• Report power consumption Monitor current flow using the current
sensing circuit.
The information in Figure 7.1 on page 199 is output on the console port every
second. The frequency at which this information is updated is adjustable via a
console command input. It can be set anywhere from never to 65,535 seconds, in
one-second increments. Serial port settings are 19,200 baud, no parity, 8 data bits, 1
stop bit.
Note: High and Low Current Detection:
A fault condition will be indicated by the LEDs and on the console until the
fault is cleared, either by the resistor detection for that port succeeding and
the port being switched ON, or disabling and re-enabling the port from
the console.
