In all modes of operation, Direct IP or Virtual Com, the port number set in the
ESP902 menu must match the Virtual COM and socket software port settings.
As an example the Virtual COM default setting is TCP/UDP Port 4000. If the
port # property is changed to 4001, then the Virtual COM TCP/UDP Port will
have to be changed to 4001. The ESP Manager or Telnet/Console
configuration can change the setting for the hardware. The Virtual COM port
setting can be changed within the Device Manager of the computer of which it
is installed.
Remote IP Address (Set for each port)
This is a security feature activated by entering the IP address of the desired
client. The ESP902 will only communicate with the listed IP address and all
other requests for connection will be filtered out. The ESP902 is set to TCP or
UDP Server in Connection Mode to use this feature.
The default setting is 255.255.255.255. If not using the paired mode, we
recommend not changing this setting until the application has been tested and
is communicating properly. Then you can activate the address filtering feature.
