following table.

Console Mode

The console mode allows access to the ESP901 setup menu. This is one way to

reconfigure the default settings for the application. A serial connection is made

between a COM port on the PC and the serial port of the ESP901 with a null modem

cable. In console mode, the serial port defaults to an RS-232 interface.

The ESP901 serial port default settings are, baud rate 9600, 8 data bits, no parity, and

1 stop bit. Hyper Terminal should be used for this type of setup. Hyper Terminal’s

serial settings are configured the same as the mentioned default settings of the ESP901

and must be set to VT100 emulation mode. The default settings are used only if they

have not been changed.

See Chapter 7 for details.

Upgrade

The newest firmware can be installed on the ESP901 using the PC’s serial port or the

Virtual COM port. Some firmware upgrades may require a new software upgrade with

the Virtual COM driver being the critical component.

See Chapter 11 for details.

Default Setting

When the switches are set to this mode the ESP901 will reset to the original default

settings.
