4.11.2 iPORT Configurations (continued)
iServer IP Address
– This is the IP address of the iServer that is connected to the serial
device on one end and attached to the Ethernet LAN on the other end. The iServer’s
default IP address is
192.168.1.200
, which can be changed to fit your network IP
address range (see
Section 3.5
).
iServer Port Number
– This is the port number for the iServer’s local serial port. The
default value is 2000. If this port number is changed in the iServer’s Configuration page
(see
Section 4.3.4
), the same number should be placed in the iPORT window.
Activate
– If this box is checked, the selected COM port will be available for network
connection. If it is unchecked, the selected COM port will be in sleep mode.
Timeout
– This is the amount of time (in milliseconds) in which the iPORT keeps the
application software waiting before the device response is arrived. The default value is 5
seconds and it can be set between 0 to 10 seconds.
Status
– This window shows the connection status as the iPORT makes connection to
the iServer or disconnects from the iServer. The connection status can be ideal,
connecting, connected, or disconnected along with the IP address of the iServer shown
in the Status window.
Apply button
– To save the configuration for a selected COM port, click on the "Apply"
button and reboot your PC for settings to take place in your Windows registry.
Clear button
– This button deletes the settings for a selected COM port.
Cancel button
– This button closes the iPORT window without saving the settings.
In
Figure 4.30
, if a COM port number is dimmed and cannot be selected, it
means that the COM port is already used by another application or it could be a
physical serial COM port on that PC.
The serial communication settings (baud rate, data bit, stop bit and parity) of
your application software must be identical to the serial communication settings
of the iServer’s serial port and your serial device’s port connected to the iServer.
You can use a Web browser to log into the iServer and configure its serial port’s
settings (see
Section 4.3.4.A
).
