4.12.2 Local iServer
1. An IP address should be assigned to the iServer dynamically or statically (recommended).
2. Use a browser to access the Local iServer's WEB page. Simply type the iServer's IP
address at the browser's URL location (i.e. 192.168.1.49) followed by an Enter key.
You should then see the iServer's main WEB page.
3. Click on the Update button.
4. Click on Configuration, you will be prompted with a Password (default is 12345678).
5. On the Configuration page, under Serial Communication section, make sure the
parameters such as Baud Rate, Data Bits, Parity, Stop Bits, Flow Control, etc. match
with your attached serial device and its application software.
6. Make sure to set the End Character (Hex) to 0D and the Timeout to 500.
7. Under Terminal Server section, set Number of Connections to 0.
8. Under Remote Access section, set the Remote Access to enable, Enter the Remote
IP address (would be the IP address of the remote iServer, 192.168.1.50), and use the
default Remote Port number 2000.
9. Set Connection Control to Reconnect and set the Connection Timeout to a desired value.
The Reconnect option is used in Serial Tunneling and it applies only to the Local
iServer. If the tunneling connection between the two iServers goes down due to
network problems, power failure, etc., the Reconnect option will enable the Local
iServer to reconnect with the Remote iServer based on the specified time interval in
the Connection Timeout. For example, based on a timeout of 1000 x 10 ms (10
seconds), the Local iServer will continually attempt to reconnect and re-establish the
tunnel with the Remote iServer every 10 seconds.
10. Click on Save button for the changes to take place.
11. Initialize the serial device application software to establish the connection.
Figure 4.22 shows
the valid values
that need to be set
in the Local
iServer. The Baud Rate,
Data Bits, Parity, Stop Bits,
Flow Control, and
Transceiver values depend
on what the attached device
to the iServer supports.
