To remotely manage and control multiple displays in Tile Mode when using either VGA or DisplayPort
video source, either a RS-232 or Network connection may be used with the HP Network Sign
Manager.
If using the RS-232 interface, the displays must be daisy chained with RS-232 cables. Attach one end
of a RS-232 cable to the RS-232 Input connector of the first display and connect to the serial
connector of the media player/computer. Then attach one end of an RS-232 cable to the RS-232
Output connector and the other end to the RS-232 Input connector of the next display and continue to
connect the RS-232 cables between each display in the tiled matrix as shown in
