INSTALLATION AND OPERATING INSTRUCTIONS

INTRODUCTION

Model IF-PX is a single zone POE in-line interface designed to extracts power
from an Ethernet connection to power Louroe microphones, speaker/microphones
and external devices that require a 12Vdc supply such as Encoders and Non PoE
IP cameras. The IF-PX supports both one-way and two-way audio. Most
commercial grade line level unbalanced microphones are compatible with this
unit. Audio output has variable gain control.

Terminal blocks are employed to receive signal wiring from a Louroe Verifact
microphone or an AOP-SP speaker/microphone. Two 3.5mm stereo male to

3.5mm stereo male audio cables are included to connect the unit to an IP camera
or Encoder. Both Mode A and Mode B power options of IEEE802.3af are
supported. Outputs for both PoE (Power+Data) and Non-PoE (Data Only)
cameras and Encoders are included. The IF-PX has built-in thermal, overload and
short-circuit protection that protects the unit from overcurrent and over
temperature. The unit shuts down and turns back ON after the fault is removed.

INSTALLATION AND OPERATING INSTRUCTIONS

CAUTION

1. Do not connect non-PoE complaint devices to Power+Data Output Jack . Failure to do so may damage the
powered equipment.

2. Do not connect wiring from external microphone or AOP-SP to the Mic/Speaker Audio Terminal Block until
all the ethernet cables (RJ45) are connected and power is present to the camera. Failure to do so in sequence,
the camera may not receive power.

NOTES

Plan ahead where to install before making any connections.The IF-PX is supplied with 6’ audio cables for connections

between the IF-PX and camera. The maximum distance between the IP camera and PSE is 100m or 328’.

CONNECTIONS AND OPERATIONS

CONNECTING PoE SWITCH TO PoE IP CAMERA OR ENCODER (See Fig. 3 and 4)

1. Connect Ethernet cable from PSE (Power Source Equipment) to the Power+Data Input Jack of the IF-PX.

2. Connect Ethernet cable from camera to Power+Data Output Jack of the IF-PX. Camera should now have power
and data running through it. Power Indicator lights up.

3. Microphone Connection :

(one-way listen)

a) Connect a 2 cond. shielded cable to the terminal block of Louroe’s Verifact microphone. Connect the other end to

the pluggable header (Mic/Speaker Audio Terminal Block ) of the IF-PX. Connect terminal A of microphone to

5

terminal A of IF-PX; terminal B of microphone to terminal B of IF-PX; terminal C of microphone to terminal C of IF­PX. Terminal SP of IF-PX is not used when connecting microphone only (one-way listen).

b) Using the patch cable (stereo plug to stereo plug), connect the Audio Output Jack of the IF-PX to the audio input

9

of the camera.

c) Adjust the Mic Out Adjust potentiometer (as needed) by rotating it clockwise to increase the microphone output to

the camera, or counterclockwise to decrease. This potentiometer is factory set for a gain of 0dB output.

See

interconnection diagram(Fig 3) on page 4.

4. AOP-SP Connection (two-way audio): Before connecting the AOP-SP series, make sure that the Ethernet

cables between the PSE, IF-PX and Camera are all connected.

a) Connect

Block) of the IF-PX. Connect terminal A of the AOP-SP to terminal A of IF-PX; connect terminal B of AOP-SP to

a 3 cond shielded cable between the AOP-SP and the pluggable header (Mic/Speaker Audio Terminal

5

terminal B of IF-PX; terminal C of AOP-SP to terminal C of IF-PX and terminal SP of AOP-SP to terminal SP of IF­PX.

b) Using the patch cable (stereo plug to stereo plug), connect the Audio Output Jack of the IF-PX to the audio input

of the camera or encoder. Connect the Audio Input Jack of IF-PX to audio output of the camera or encoder. See

interconnection diagram on page 5.

c) See installation instructions of AOP-SP for setting up and operation of the unit.

5. Setup camera for video and audio monitoring. Use an amplified speaker and a microphone to test the audio. A push

to talk microphone is recommended to minimize the echo when doing two-way audio. See camera user manual for
setting up the camera to the network.

The IF-PX can power most IP cameras and Encoders, check that the power requirements of the equipment does
not go beyond the IF-PX power output. See IF-PX power output below.
Power output of IF-PX:
12Vdc, 650mA with AOP-SP connected
12Vdc, 850mA with a Louroe microphone only connected

CONNECTING PoE SWITCH TO NON-PoE IP CAMERA OR ENCODER (See Fig 5)

1. Connect Ethernet cable from PSE (Power Source Equipment) to the Power+Data Input Jack of the IF-PX.

2. Connect Ethernet cable from camera to Data Out Only Jack of the IF-PX.

INSTALLATION AND OPERATING INSTRUCTIONS

3. Connect 2 wires to the DC Out Terminal Block . At least 20 AWG wires should be used between the IF-PX and the

3

encoder or camera. Positive 12Vdc connects to terminal marked “+12Vdc” of IF-PX. Negative 12Vdc or ground
connects to terminal marked “GND” of IF-PX. Connect the other end of the 2 wires to the power jack or terminal block
of the encoder or camera. If the encoder or camera has a 2.1mm power jack, an adapter (2-pin terminal block to

2.1mm male plug) can be used. Connect the wires to the 2-pin terminal block (observe polarity) of the adapter. Plug
the adapter to the 2.1mm power jack of the encoder or camera.

4. Repeat same procedure when connecting Louroe Verifact microphone or AOP-SP (steps 3 thru 5 from the previous
page - Connections and Operations).

CONNECTING NON-PoE SWITCH TO NON-PoE CAMERA OR ENCODER (See Fig. 6 - Encoder shown)

1. Connect Ethernet cable from Non-PoE Switch to the Power+Data Input Jack of the IF-PX.

2. Connect Ethernet cable from Encoder or Camera to Data Out Only Jack of the IF-PX.

3. Connect DC Out Terminal Block to the power input jack of the encoder or camera. This Terminal block supplies

3

7

12Vdc power to the camera or encoder. It can also provide power to other external equipment such relays, etc. that
require a 12Vdc power. Connect 2 wires to the DC Out Terminal Block . At least 20 AWG wires can be use between

3

the IF-PX and the encoder or camera. Positive 12Vdc connects to terminal marked “+12Vdc” of IF-PX. Negative 12Vdc
or ground connects to terminal marked “GND”of IF-PX. Connect the other end of the 2 wires to the power jack or
terminal block of the encoder or camera. If the encoder or camera has a 2.1mm power jack, an adapter (2-pin terminal
block to 2.1mm male plug) can be used. Connect the wires to the 2-pin terminal block (observe polarity) of the
adapter. Plug the adapter to the 2.1mm power jack of the encoder or camera.

4. Connect an external power supply (not included) to the DC In Jack to power the IF-PX and the encoder or camera.

4

We recommend using a 12Vdc, 2A power supply.

5. Repeat same procedure when connecting Louroe Verifact microphone or AOP-SP (steps 3 thru 5 from the previous
page - Connections and Operations).
