4.4 Setting a New IP Address using the Serial Port
Once you know the IP address that you need to put on your iServer you can use a serial
connection (Terminal Emulation) to assign the IP address to the iServer.
Setting the IP address over the serial port requires a crossed-over (null modem) serial
cable and Hyper Terminal or any terminal emulation program. When all the connections
are done, change the DIP switch
#1
to
"ON"
position and press the Reset button or reset
the power on the iServer. The Hyper Terminal screen will acknowledge your connection
by asking for the command.

in
“ON”
position
Figure 4.14 DIP switch #1
Type "
IP=xxx.xxx.xxx.xxx
" and press Enter.
The screen will acknowledge that your command was executed.
You can also set the iServer’s gateway and subnet mask by typing
"
GW=xxx.xxx.xxx.xxx
" and "
SM=xxx.xxx.xxx.xxx
", respectively.
Then type
q
and press Enter
You can now change the DIP switch
#1
back to the
“OFF”
position and reset the power
on the iServer.
Figure 4.15 Setting the IP address via the Serial Port
You can access the iServer’s complete settings by connecting the iServer’s serial
port to your PC’s COM port using a null-modem cable.
Bring up a terminal emulation program (i.e. HyperTerminal) and make sure the
right COM port is selected and the serial communications settings (baud rate,
character bit, stop bit, and parity) match the iServer’s serial port.
Power the iServer
ON
and press the Enter key
within 5 seconds
of powering the
iServer.
The iServer will then transmit its complete configurations to the PC.

You need to make sure to setup the
following parameters on your terminal
emulation program (i.e. Hyper Terminal)
Baud Rate
- 9600 b/s
Data Bit
- 8 bits

- None
Stop Bit
- 1 bit
Flow Control - None
Local Echo - Enable
Line Feeds - Enable
Sending three “Control A”
characters will do the same as
setting DIP switch
#1
to
ON
position. Once the “Ctrl A”
characters are received by the
iServer, the Serial Port will
switch to “Command” mode.
