Listening Port Programs
Many different types of programs are available to use to respond to incoming communications.
Modbus Slave, Basic Programs, or a VNC server can be chosen to communicate on a listening
port.
Modbus Slave can respond to Modbus Master requests on any specified port of the system.
Basic Programs can be useful for serial or network-based actions, such as emulating a DRGS
using the DAMS-NT protocol. Other programs could emulate simple web pages or provide Task
information or system statistics to requesting clients. Even other loggers could request and
retrieve information using a simple Basic script. Example commands and programs can be found
within the Basic 5000 User Manual, downloadable from the waterlog.com web site.
The VNC Server provides direct access to the same menu system seen through the touchscreen
and thus enable remote communication, configuration, and data retrieval from the system via a
network connection. As the VNC Server also supports file transfers, remote Basic Programs
could be installed, firmware could be updated, or configuration files could be saved or loaded all
from a remote location. For more information regarding using the VNC Servers to remotely
connect to and manage the System 5000
, please refer to Chapter 13.

Configuring Network Listening Ports
Network Listening ports can respond to incoming requests whenever the System 5000 is not in
TM
its low-power sleep. The System Timeout can be disabled in the System Settings to prevent the
System 5000
from entering its low-power sleep. Few settings are needed to configure a
TM
network port: the network port itself, and the network mode/interface.
Mode: Most ports will use TCP as their interface. UDP, if needed, can also be selected.
