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.

3.	Pass two 4-40 x 3/16" screws up through the floor of the PMK into the holes in
	the base of the switcher, and secure it in place using an Extron Tweeker or a
	Phillips #1 screwdriver.
4.	Install the power supply on the right rear of the PMK 450 bottom plate and
	secure it using Velcro©.
5.	Install any other desired devices on the PMK 450, following the installation
	steps in the devices’ user manuals.
6.	Lift up the plate (with the devices installed) to the pole, and connect the
	twisted pair, audio, control, and power cables (see “Rear Panel Features and
	Cabling”, in this chapter, for details).
7.	With all the cables connected, slide the lugs on the bottom plate into the
	notches on the top plate and secure with screws.
8.	Replace the front, rear, and filler plates.
9.	If installing the full PoleVault™ system, continue installing the rest of
	the hardware, devices and cabling, referring where applicable to the
	instructions in the relevant user manuals. See pages 1-4 and 1-5 in chapter 1,
