EM1500 User’s Manual

When you click on the EM1500 icon to select it, the GUI sends a message over the network to the selected
unit, telling it to send status updates on a regular basis, or when anything changes. After that, the EM1500
is responsible for sending messages to the GUI so that it can update the display in “real time.” This works
best for local LAN connections, but can also work over the Internet with, usually, a reduction in response
times.
The listbox and status/debug area are pictured below. One EM1500 responded to the broadcast, so only
one unit shows up in the listbox. It has been selected, which causes information for all of the serial ports to
display in the status window.
Figure 5.13 Status Area of Stand-Alone Configuration Program
It is divided vertically into six areas that we will refer to as trays.
Some of the items on the display are “buttons” and some are just “labels,” which we will call “LEDs.”
Both buttons and LEDs display in different colors to indicate the status of that control.
