This panel is used to modify the communications connection settings for

the currently selected display in the layout.

Connection types of RS232 or LAN (Ethernet) can be selected.

Is using RS232, the RS232 COM port on the host PC used to communicate

with the displays can be selected. Currently available COM ports on the

host PC are listed in COM Port:.

Otherwise, if using LAN, the IP Address of the display can be entered.

See Chapter 8 for instructions on how to assign the IP address for each

display. For display models that have LAN daisy-chain connections (see

“LAN Daisy-chain” on page 20), the Search... function can be used

to locate displays that are connected to the LAN and automatically ll in

the correct IP address.

For both communications types, the Monitor ID of the display must be

selected and this must match the ID selected on the display’s OSD setting. If displays are daisy-chained together

using RS232, each display must have a unique Monitor ID assigned that must match that set on the display’s OSD

setting.

The communications settings and link to the display can be tested by clicking the Test button. This will attempt to

communicate with the display on the selected communications interface and Monitor ID.

Clicking the Update button will update the communications connection settings for the currently selected display

in the layout.

Note: If changes have been made, but the Update button has not been clicked, then the changes will be lost if another

display is selected in the layout.

Note: (Windows version only) COM ports 1-16 are listed, regardless of if they are installed on the system. COM ports that are

reported as available by Windows are shown with a green check mark and COM ports reported as unavailable are

shown with a red cross mark .
