a. Pass the legs of the U-bolt through the slotted holes on

		the mount plate flange.
	b.	Place the legs around the projector pole.
	c.	Pass the legs through the holes in the contour base.
	N The pole fits snugly into the depression in the center
		of the contoured base.
	d.	Pass the U-bolt legs through the holes in the L-shaped
		bracket.
	N The supplied U-bolt fits a typical (1.5" to 2.0"
		diameter) ceiling pole.
7.	Align the two slotted holes in the bottom of the L-shaped
	bracket with the two slotted holes in the base of the tray.
	Secure the L-shaped bracket to the base by inserting two
	provided 6-32 x 5/16" screws through the aligned slots.

Figure 2-9 — FOX HD-SDI transceiver’s connectors

A		HD-SDI Input connector — If the FOX HD-SDI is configured
		as either a bidirectional transceiver or as a transmitter, connect
		an HD-SDI, SDI, or 3G-SDI video input to this BNC connector.
B		Mode switches — Set these DIP switches to the positions shown
		in the table below to select the transceiver configuration. See
		"Transceiver configurations" on page 1-3 for more information.
			SW1	SW2	Mode
MODE			Down	Down	Bidirectional transceiver (default position)
			Down	Up	Transmitter with local monitor outputs
			Up	Down	Receiver with daisy chaining
	1	2	Up	Up	Spare (functions as receiver with daisy chaining)

C Fiber optic connectors —

WThis unit outputs continuous invisible light, which may be harmful and dangerous to the eyes; use with caution. For additional safety, plug the attached

dust caps into the optical transceivers	OPTICAL
when the fiber optic cable is unplugged.

8.	Move the PMK 350 up to the desired location on the ceiling
	pole, as close to the ceiling as desired.
9.	Secure the L-shaped bracket to the U-bolt using the
	included hex nuts, washers, and lock washers. Tighten the
	hex nuts securely.

NBe sure to tighten the hex nuts securely enough that the PMK 350 does not slide down the ceiling pole. A socket wrench is recommended to tighten the hex nuts.

10. Secure the front panel to the mounting tray with four of the included #6 screws.

11. If desired, choose one of the provided four sizes of self- adhesive cover sheets, and apply it to the underside of the mounting tray.

NEnsure that you use the proper fiber cable for your transceivers. Typically, singlemode fiber cable has a yellow jacket and multimode fiber cable has an orange jacket. Also, see "Fiber Compatibility Indications" on page 2-14to determine the transceiver's compatibility.

Tx — In any FOX HD-SDI configuration, for all one- way HD-SDI, SDI, or 3G-SDItransmission, connect a fiber optic cable to the Optical Tx LC connector.

Connect the free end of this fiber optic cable to the Optical Rx connector on another

FOX HD-SDI transceiver that is configured as a bidirectional transceiver or as a receiver.
