1. For mounting information, please refer to the Installation Instructions provided by Peerless
Manufacturing inside of the box of the MIS741-A2.

2. Connect the NEC displays using the included DVI cables and the integrated DVI
loopthrough connections on the bottom of each monitor. Note that the DVI connection
closest to the front of the display is the ‘in’ connection while the connection closest to the
wall is the ‘out’ connection.

The ideal cabling set up is shown below to match the ideal monitor ID configuration.
However, DVI daisy chaining can be done different ways and still yield the same results.
Note that the connections for each X551UN monitor are on the bottom of each display, not
the side as shown in the image below. It may be helpful to start wiring before mounting.

3. Connect the null modem cabling to each display. It is recommended to connect from
Display 1 to Display 2, from Display 2 to Display 3, and from Display 3 to Display 4. Note
that the null modem cable needed to run from the source computer to Display 1 is not
included in this bundle. This will need to be purchased separately to control the display
remotely over RS232. Also loop through the provided IR Remote control cables.
