1 AUDIO INPUT

Sources

These are the RCA unbalanced line level audio inputs for each of the 8 sources.

The top RCA connector is the left channel, bottom RCA connector is the right channel.

7 VGA INPUT

These are high densisty 15pin D connector VGA inputs for the PC1/PC2/AUX3/

AUX4 sources.

2 MIX IN

8 VGA OUTPUT

This is the high densisty 15pin D connector VGA output. This output only outputs the signal from PC1/PC2/AUX3/AUX4 sources if selected.

This input is not switched but mixes with the selected audio source. The bass/ treble/volume controls do not affect this input. This feature can be used in paging environments or emergency systems in conjuction with the L1 trigger input.

9 RS485

This 5.08mm pluggable connector socket is provided for external control of the

IN400 using RS485.

3 AUDIO OUTPUT

These are the left (top) and right (bottom) RCA unbalanced line level outputs.

4 AMP OUT

The IN400 has a built in audio stereo power amplifi er. The input signal is parallelled from the AUDIO OUTPUT. The power amp is rated at 2 x 80W into

4 ohm, 2 x 50W into 8ohm. The minimum load is 4ohm. The outputs are on a

5.08mm pluggable connector.

10 L1

This input is used to mute the audio outputs. The MIX IN is not affected. This feature can be used in paging environments or emergency systems. Short it to the RS485 ground pin to activate it.

5 VIDEO INPUT

These are RCA unbalanced 75ohm composite video inputs for the DVD1/DVD2/

AUX1/AUX2 sources.

11 IEC MAINS INPUT SOCKET

This is a standard IEC 3 pin socket (IEC320-C14). It accepts a standard

IEC mains cable, provided. The fuse draw contains the mains fuse and a spare.

The mains fuse is a time lag (slow blow) HRC 20mm x 5mm fuse.

The ratings are:

230V Model T3.15A

120V Model T6.3A

6 VIDEO OUTPUT

These are the RCA unbalanced 75ohm composite video outputs. OUT1 and

OUT2 output the same signal but they are individually buffered. These outputs only output the signal from DVD1/DVD2/AUX1/AUX2 sources if selected.

Always replace the fuse with one of the same value and type.

Note: Always disconnect power to the amplifi er before replacing fuses.

The IN400 data port is an RS485 serial data port. Twisted pair cabling should be used when connecting

RS485 devices, such as CAT3, CAT5, CAT5e or CAT6 UTP cabling. RS485 data networks should be wired in a ‘daisy chain’ confi guration with a maximum of 32 devices in the chain. The IN400 is not terminated so may be inserted anywhere in the data network. If the IN400 is being used at the end of a chain, a 120ohm (characteristic impedance of UTP) terminating resistor should be connected between the + and - connections.

The IN400 has built in failsafe bias circuitry so there are no need for external biasing resistors.

The maximum length of the chain is 500m.

PAGE 6 IN400 INSTALLATION AND OPERATION MANUAL

INSTALLATION

All installation work should be done with the power disconnected. The following inforamtion will help with installation. After installation is complete power up all the sources before turning on the IN400.

POWER CONNECTION OUTPUT CONNECTIONS (cont.)

Ensure the mains voltage supply matches the rear of the IN400 (+/- 10%)

Ensure that all system grounds (earth) are connected to a common point. Avoid powering equipment within a system from multiple power sources that may be separated by large distances. This will eliminate ground loops that are heard as

50/60Hz humming or buzzing in speakers and seen as moving or stationary bars on video equipment.

Video

Video outputs are on either unbalanced RCA sockets (composite) or 15 pin high density female connectors D-connectors (VGA). The maximum cable length for composite video is typically less than 3m for shielded wire and 10m for coaxial before signal degradation. This will depend on the cable quality.

There are two composite outputs for running to 2 different monitors without the need for an external distribution amplifi er.

INPUT CONNECTIONS

Audio

All the inputs are unbalanced RCA sockets. Unbalanced RCA wiring should be keep as short as possible. Typically less than 3m.

Video

Video inputs are on either unbalanced RCA sockets (composite) or 15 pin high density female connectors D-connectors (VGA). The maximum cable length for composite video is typically less than 3m for shielded wire and 10m for coaxial before signal degradation. This will depend on the cable quality.

Test Procedure

VISUAL INSPECTION STAGE

1. Physical checks

•

•

All screws for tightness, referring to the torque setting of the manufacturing tools

Capacitors for polarity where applicable

• All wiring points for good contacts (soldering and crimping)

PRETESTING

PRE TESTING SETUP REQUIREMENT a) Oscilloscope b) Variac c) Multimeter d) Load [8ohm]

2. Set up device for test :

2.1. Fuse check

2 x DC fuses (3.15A), 20x5mm

1 x AC fuses (2A), 20x5mm

2.2. Connections

Connect unit to:

Variac (240Vac), power initially off

Signal generator (DVD1 left input, no signal)

Resistive load (8ohm on left amplifier output) with meters/oscilloscope

3. Power up :

Adjust voltage to 240VAC. Turn on variac power. Watch current meter for excess current draw.

(P/F) Current shall not exceed <?>A (AC current)

3.1. Voltages

(P/F) Measure the following DC voltages with a multimeter referenced to ground testpoint TP6 on the 07900 PCB.

Low Rail Filtered Pos U7 pin 1

Low Rail Filtered Neg U8 pin 2

Regulated +5V

Regulated -5V

TP1

TP3

7VDC to 10VDC

-7VDC to -10VDC

4.7VDC to 5.3VDC

-4.7VDC to –5.3VDC

High Rail Filtered Pos TP4

High Rail Filtered Neg TP5

35VDC to 39VDC

-35VDC to -39VDC

4. Programming :

Connect the programming pod to connector CN11 and follow the programming procedure document.

(P/F) The programming must complete successfully.

5. Functional Checks :

5.1. General Operation

Ensure that power is applied to the unit. On first power-up, all front panel indicators should be OFF.

(P/F) Press the power button. The power LED should light. Source Off should be by default active and the LED above it lit.

(P/F) Press the source DVD1 button. The LED above it should light.

(P/F) Press the source DVD2 button. The LED above it should light.

(P/F) Press the source AUX1 button. The LED above it should light.

(P/F) Press the source AUX2 button. The LED above it should light.

(P/F) Press the source AUX3 button. The LED above it should light.

(P/F) Press the source AUX4 button. The LED above it should light.

(P/F) Press the source PC1 button. The LED above it should light.

(P/F) Press the source PC2 button. The LED above it should light.

(P/F) Rotate the rotary encoder in either direction to ensure that all LEDs can be lit, one at a time. Ensure that there are no strange “jumps” in the lighting pattern.

Note that source PC2 should still be selected for this test.

(P/F) Move the rotary encoder such that the highest volume LED is lit (fully CW).

On the rear panel, connect logic input L1 to the ground pin in the same 4-way connector. The lit volume LED should commence flashing. Disconnect L1 from ground. The volume LED should stop flashing.

(P/F) Move the rotary encoder and observe the Comms LED. It should briefly flash with each movement of the encoder.

5.2. IR Operation

Ensure that the power LED of the unit is lit. If not, press the power button.

(P/F) Press each button on the IR remote control supplied with the unit and verify that for each button, the Comms LED on the main unit flashes briefly. Depending on the button pushed, the unit will light other LEDs and change volume etc but this can be ignored at present.

5.3. RS485 Operation

Ensure that the power LED of the unit is lit. If not, press the power button.
