nonvolatile memory (NVRAM)

8

ON

DOWN

2Connect the modem to a PC. If your computer’s RS-232 port has a 25-pin connector, use a DB-25 male to DB-25 female RS-232cable. If your computer’s RS-232 port has a 9-pin connector, use a DB-25 male to DB-9 female modem cable.

3Power-up the modem.

4Run a serial communication port program such as Hyperterminal.

5Within the communication program, select the port to which the modem is connected.

6Configure the port to these settings:

baud rate = 9600, 19200, 38400, 57600 (Must match Baud Rate configured in HC900 Controller)

data bits = 8 parity = none stop bits = 1

flow control = none

7In the program's terminal window, restore factory defaults by keying-in the following command string:

AT &F0

Then, press the ENTER key.

The modem should respond with OK.
