Remote Access - Pcpro Via Modem - NEC XN120 Getting Started Manual

Remote Access - PCPro via Modem

Before you can use PCPro to communicate with the XN120 via the modem connected to the
EXIFU you must carry out the following steps:
1. Setup the serial port of the EXIFU to accept the remote access via the modem.
2. Setup the modem for connection to the serial port EXIFU card.
3. Connect the modem to the serial port.
4. Setup the dialling in method to access the modem.
5. Setup a 'dial up session' on your PC.
1. Setup the EXIFU serial port to accept remote access via a modem.
You will need to setup the serial port of the EXIFU card before it will operate correctly when it
is connected to a modem for remote access with PCPro.
To do this you will need:
· The EXIFU card installed in XN120 system.
Ensure the link CN10 on the EXIFU card is set to N (when set to D the serial port will be
used for debug operation).
The XN120 must be powered on.
Confirm the Baud rate of the serial port with Program 10-21-02 (default = 2 which is 19200
bps, change this to 3 for 38400 bps to increase the up/download speed)
· Your PC with a Terminal Application available.
The Terminal Application should be set to use a COM port on your PC (eg COM1) with
the same Baud rate and serial settings as the EXIFU card.
19200bps (or 38400bps)

·
A Null modem (serial cross) cable.
Connect the COM port of your PC to the serial port of the EXIFU card using a Null Modem
(serial cross) cable. The pin connections of the serial cross cable are shown earlier in this
guide.
· Within the Terminal Application:
Type AT (return) to confirm the connection to the EXIFU card – you should see OK on the
screen, if not re-check the steps above.
Type ATR1 (return) – you will now see AT printed on the screen every 5 seconds.
Type AT&W – to save the setting to the EXIFU card. This is very important; if the ATR1
setting is not saved then remote access will not be available if the XN120 is
powered off.
You can now unplug the serial cross cable from the EXIFU.
2. Setup the modem for connection to the serial port of the EXIFU card
You will need to check the modem has the correct setup before you connect it to the EXIFU
card.
·
Plug the serial port of the modem to the COM port of your PC with a straight serial cable.
·
Within the Terminal Application:
Type AT (return) to confirm the connection to the modem – you should see OK on the
screen, if not re-check connections and terminal settings.
Type AT&C0 (return) – you will see OK on the screen.
Type AT&W – to save the setting to the modem. This is very important; if the AT&C0
setting is not saved then remote access will not be available if the modem is
powered off.
You can now unplug the serial cable from the COM port of your PC.
