Chassis Assembly
WARNING: The chassis weighs 65 lb (29.5 kg). Two people are required to handle and position the display safely.
Unpack the PMCD750 unit. The screen is not needed yet and should be left in its container at this time.
SINGLE DISPLAY
Attach the screen support to the front edge of the chassis with the supplied screen support bolts. The screen support mounts only one way.
It incorporates a stop (rest) for the screen. Refer to Figure 1.
WALL DISPLAY – FIRST ROW
Straightness of the PMCD750 display is critical because the screens have no mullion (outside screen border). If the first row in a wall
configuration is not horizontally straight, the problem will worsen as construction progresses.
To build the first row of a wall:
1. Set the first row of PMCD750 units side by side without the screens. Bolt them loosely together through the bottom connection points with
the 1/4-20 x 3.5-inch bolts, washers, and wing nuts. Refer to Figure 1.
2. Attach the screen supports to the front edge of each chassis. Refer to Figure 1.
3. Check the first row for horizontal straightness by making sure the front and top edges of adjacent units are flush. If necessary, use shims
under the units to make sure the top edges of adjacent units are flush.
4. When the first row is straight horizontally and vertically, tighten the bolts holding the units together.

WALL DISPLAY – SECOND ROW AND UP
DANGER: Because the PMCD750 unit has a narrow front-to-back profile, the danger of tipping exists with high walls. For walls over two
units high and all tilted walls, use the four tie-back points (1/4-20 threaded holes) on the rear of the unit to secure the video wall to a
structural part of the building. If the wall is tilted forward, tie the wall all the way up. Do this as the wall is being built up; do not wait until
the wall is finished. Pelco does not provide any special brackets to secure the PMCD750 unit. The method to use is best determined on site
due to the many variables to consider, and must be capable of sustaining five times the weight of each PMCD750 unit – a total of
340 pounds (154 kilograms) per unit.

WARNING: The maximum stack height for a wall is four units.
1. Stack another row of PMCD750 units on the first row. As you stack, be careful inserting the alignment pins on the second row chassis into
the alignment holes on the lower unit. Refer to Figure 3.

3. Bolt the PMCD750 units together vertically through the vertical connection points using the 1/4-20 x 3/8-inch bolts. Refer to Figure 5.
4. Bolt the PMCD750 units together through the bottom connection points the same as the first row. Refer to Figure 1.
5. Bolt the PMCD750 units together through the horizontal connection points using the 1/4-20 x 2-inch bolts, washers, and wing nuts. Refer to
Figure 5.
6. Continue in this way with the rest of the rows, checking straightness as each row is completed.

Connecting RS-232 and RS-485 Control
Serial control can be used with stand-alone units, a wall, or several walls.
To connect an external controller:
1. Using a straight-through computer serial cable, connect the RS-232 input of the stand-alone unit or the first unit in the wall to the serial out
port of the external control device, such as a video controller. Refer to Figure 7.
2. Connect this first display’s RS-485 Out to the next display’s RS-485 In. Refer to Figure 7.

Installing Screens
To install a screen on a stand-alone unit, follow the instructions in steps 1a, 1b, and 1c.
1. To install the PMCD750 screens, start in the middle of the bottom row and install that screen. The screen supports should be installed on
the bottom row of PMCD750 screens.
a. Pull the screen rails all the way out on both sides of the PMCD750 chassis. The screen rails each have a large pin that mates with the
L-shaped slot located on each side of the screen. Refer to Figure 8.
b. With one person holding each side, hang the screen so that the pins on the screen rails go into the L-shaped slots on the sides of the
screen. Refer to Figure 9.
c. Slide the screen closed, lifting it slightly to avoid scraping on the screen support below.
2. Install the screens to the left and right of the center screen to complete the bottom row. After adding a screen, press it toward the center.
If necessary, place shims on the top of the screen support until the screens are straight.
3. Starting in the second row and working upward and outward, finish all the rows.

Connecting Power
1. Bring AC power next to the electronics module. Connect the power to the receptacle located on the rear panel. The voltage can be
115 VAC (90–132 VAC) or 230 VAC (200–254 VAC). Refer to Figure 10.
POWER SWITCH
AC OUT
AC IN
Figure 10. Power Switch and Receptacles
WARNING: Do not exceed the recommended number of PMCD750 units linked in series for AC power or the current draw will be too great.
2. The AC power can be looped through to the next PMCD750 unit, resulting in fewer main outlet sockets needed for operation. The total
number of units in one power loop cannot exceed four (115 VAC) or eight (230 VAC) units.
3. Turn on the power switch for each display. When AC power is applied, there are a few seconds of apparent inactivity in which the
electronics module begins start up and initialization. Next, if the optical engine is warm, the intake and lamp fans start. Because the
service life of the lamp can be significantly shortened if turned on when hot, the lamp cannot be turned on during this time. The lamp fan
runs for approximately one minute to ensure the lamp is cool. If the temperature sensor on the optical engine determines that the lamp is
sufficiently cool at power up, this cool-down period is skipped.
NOTES:
•
The AC switch on each PMCD750 unit controls that display only. Turning off the switch on any display does not cut the AC power to the other
displays. The switch is lit when it is ON and there is AC power to the PMCD750 unit.
•
The AC input is fused with a 10 A fuse. If the fuse in any PMCD750 unit blows, all displays downstream from this one will go off.
SHUT-DOWN SEQUENCE
WARNING: Turning off the PMCD750 display by turning off the power switch does not allow the lamp to cool down properly. Turning the
display off by this method may significantly shorten the service life of the lamp.
The lamp fan runs continuously while the lamp is on. When the lamp is turned off, the intake fan shuts off 15 seconds later, while the lamp fan
continues to run for an additional 5 minutes to cool the lamp. If the display must be disconnected from power, do the following:
1. Press OFF on the remote control.
2. Wait for the lamp fan to stop running.
3. Press the AC power switch on the rear of the display to turn off the power.
4. Remove the power cord from the AC in receptacle.

Using The Remote Control
Using the the remote control is the only way to access menu settings. There are no access controls on the display unit.
The remote control projects a series of IR (infrared) pulses to the PMCD750 display for control. Aim the remote control at a single display and
press MENU. The main menu should be visible if the lamp is on. Refer to Figure 11 for remote control buttons and their associated commands/
actions.

Alignment and Adjustment
If the image on the screen is not positioned accurately, alignment of the optical engine may be required. It is important to check this mechanical
adjustment of the optical engine before any electronic adjustments are made to the picture. Refer to the Aligning the Optical Engine section of
the Installation/Operation manual.
If the aspect ratio of the image does not match that of the display, scaling and cropping adjustments can be made to compensate. Refer to the
Scaling and Cropping section of the Installation/Operation manual.
