2.2.2 CONSOLE Port

For local management through the command line interface (CLI), use a computer with
terminal emulation software configured to the following parameters:
• VT100 terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the console cable to the CONSOLE port of the MM-7201.
Connect the female end to a serial port (COM1, COM2 or other COM port) of your computer.

2.2.3 ALARM Port

The ALARM port has input pins and output pins.
A closed circuit on the ALARM input pins indicates an alarm. Pins 3 and 7 are alarm input
one. Pins 4 and 8 are alarm input two. Pins 5 and 9 are alarm input 3.
The MM-7201 signals an alarm when it detects an alarm on the ALARM input pins or in the
MS-7206 system (for example, the voltage or temperature is outside the normal range). To
signal an alarm, the MM-7201 opens the circuit for pins 1 and 6 (the common pin) and closes
the circuit for pins 2 and 6.
