the
Configuration Menu
can be accessed from a PC
by connecting its RS-232 serial port to the ESP901 serial port or
ESP902 Serial Port 1. Since the computer is a DTE device, and the
serial ports are configured as DTEs (with DB-9M connectors), a null
modem crossover cable must be used.
In
Console Mode
the default serial port settings are:
9600
baud,
8 data
bits
,
No parity
, and
1 stop bit
. From Windows, HyperTerminal with
