Extron electronic manual Mounting the Switcher, Installing the PVS 204SA on the PMK

Mounting the Switcher

The PVS 204SA can be mounted on the Extron PMK 450 (Pole Mount Kit), which should be installed above the projector. The low profile of the PVS switcher and the PMK 450 allows them to be installed in tight spaces. To install the PVS 204SA on the PMK, follow the steps shown in the instruction guide supplied with the PMK 450. If the PMK 450 is already installed, do the following:

1. Remove the front, rear, and filler plates and separate the top and bottom plates of the PMK (see figure 2-1).

NDo not install the rubber feet on the PVS 204SA when installing the device in a PMK 450.

2. Placing the PVS 204SA on the PMK, align the two diagonally opposite securing holes (located in the base of the switcher) over two suitable holes in the floor of the PMK.
