RS-232, RJ-11 Serial Port

The 6-pin, RJ-11 “modular phone jack”, RS-232 port is used for the following purposes:

Products	Purposes of Port
ƒ IC693CMM321(AAUI-only Type)	Local Station Manager connection (only).

ƒIC693CPU374

ƒIC697CMM742

ƒ	IC693CMM321 (10Base-T Type)	Local Station Manager connection AND
	IC693CPU364
ƒ		Software Loader connection (for updating
		firmware).

Port Settings

The serial (COM) port of the terminal or PC that is connected to the Ethernet Interface must use the same communications parameters as the Ethernet Interface.

The default values for the Station Manager port are 9600 bps, 8 bits, no parity, and 1 stop bit. If the Ethernet Interface is configured with default values for this port, or the Ethernet Interface has not been configured, use these default values. If the Ethernet Interface is configured with non- default values for this port, use those values for the serial port settings of the terminal or PC.

The default values for the Software Loader port (this connector is used as the Software Loader port only for those modules specified in the lowest row of the table above) are 19,200 bps, 8 bits, Odd parity, and 1 stop bit. If the Ethernet Interface is configured with default values for this port, or the Ethernet Interface has not been configured, use these default values. If the Ethernet Interface is configured with non-default values for this port, use those values for the serial port settings of the terminal or PC.
