Overview

Part of our HD View™ modular multimedia transmission
system, these receivers may be inserted directly into your NEC

to 1000 feet (304.8 m).

These units are compatible with HD View Transmitters
(AC3000A, AC3008A, AC3016A), Line Splitters (AC3001A,
AC3002A), Receiver (AC3005A), and Tuner (AC3006A).

Installation Steps

1. Turn the display off completely, using the hard on/off switch, or disconnect the equipment fully from the main power supply.

2. The receiver must be placed in the plug-in slot designed for this purpose. It is located on the left side of the display near the
carrying handle.

3. Remove the carrying handle by loosening the two Phillips-head screws.

4. Remove the cover panel over the plug-in slot by loosening the two Phillips-head screws.

5. Ensure that the receiver is inserted wtih the right orientation. Orientation is correct when the tuning port is on top and the
connector labeling is not upside down.

6. Use the screws that previously held the cover panel in place to secure the receiver.

7. Re-attach the carrying handle. Ensure that the screws are properly tightened (1.39 – 1.89 Nm torque).

8. Connect the CATx cables between the system ports of the Broadcaster and the Receivers.

Operating and Maintenance

1. Understanding LEDs: The table below explains the functions of the LEDs of the units in the system. There are very short
interruptions that can be observed in the “On“ state of the LED caused by presence scanning that the Transmitter performs.

Unit LED Function

Transmitter/Broadcaster Front Panel – Green Power Indicator

Green – Power Indicator

AC3003A-NEC and AC3004A-N EC Rear Panel – RJ-45 System Port Green/ Yellow

Yellow solid – Unit is connected to the system

Yellow blinking – Bi-directional RS-232 communication (only possible when

using one receiver at a time)

2. Tuning: In order to achieve the best possible picture quality, you must tune the system. You can tune the system from the
Transmitter position or from the Receiver itself. By tuning from the Receiver, you have the advantage of being able to see the
tuning, right on the screen. To tune from the Broadcaster position, please see the Transmitter‘s user guide; to tune from the
Receiver‘s position, connect the Serial Download cable to the Receiver Tuning Port and the Serial port of a computer that
carries the Service Utility. See Figure 1 below.

Troubleshooting

1. If the green LED is not on:

a. Is the receiver correctly positioned in the slot? Are the screws tightened?

b. Is the display turned on?

2. If the LED is on, but there is no picture:

a. Have you selected "Option" as input?

b. Although it is unlikely, please check to see if the dip switches in the back of the unit (behind the black 60-pin connector) are

in the correct position. The dipswitches on the unit must be set as follows:

Position 1 2 3 4

State Off Off On On

3. If the picture is out of focus:

a. Has the correct resolution been set?

- NEC MultiSync® LCD4020, LCD4620: 1360 x 768

- NEC M40, M46 and MultiSync LDC5220, LCD6520, L&P: 1920 x 1080

b. The display has possibly been set up for a different size. Press the “Size“ button on the remote control until “standard“ is

displayed in green in the top right-hand side of the screen.

c. Has the unit been tuned properly? [See “Operating and Maintaining Instructions / Tuning]
