10. Secure the L-shaped bracket to the square U-bolt using the
included hex nuts, washers, and lock washers. Tighten the
hex nuts securely.
N Be 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.
11. Secure the front panel to the mounting tray with four of
the included #6 screws.
12. If desired, choose one of the provided four sizes of self-
adhesive cover sheets, and apply it to the underside of the
mounting tray.
Cabling 15-pin HD Connections
1. Power off the computer and its local monitor.
2. Connect the computer’s VGA output to the “Input” of the
distribution amplifi er. See Front Panel Features.
3. Connect the computer’s monitor to the “Local Monitor”
output and connect the display device to the "Output" of
the distribution amplifi er. See Rear Panel Features. Set the
DIP switches for the input and output impedance, and set
the gain/peaking DIP switch for the "Output" device.
4. Plug in the distribution amplifi er's power supply and
power on the local monitor, computer, and display device.
Cabling BNC Connections
Use an Extron SY adapter to connect the P/2 DA2xi's
15 HD VGA output to a display device's 5 BNC connectors.

a Power supply — Connect the included external 12 VDC , 1 A
power supply to the 2-pole 3.5 mm captive screw connector. Be
careful to observe the correct polarity. See Power supply wiring in
the following section for wiring instructions.
b Local Monitor connector — Connect the computer's monitor to
the 15-pin HD connector.
c DIP Switches —
Switch 1 (sync input impedance) – Default setting is down
(510 ohms). If the image from a laptop computer becomes
unstable, slide the switch up (10k ohms).
Switch 2 (sync output impedance) – Default setting is up
(50 ohms). If the front LED is green and all the input and output
cables are OK, but there is no image at the projector, slide the
switch down (75 ohms).
Switch 3 (video gain/peaking) – Slide the switch down (off) if
the output cable length is under 100' (30 m). Slide the switch up
(on) if the output cable length is over 100' (30 m).
N The gain/peaking switch does not affect the Local
Monitor output.
