RF-Link XL-2000/H, XL-2000/2, XL-2000/HP Installation And Operating Instructions Manual

2.4 GHz Wireless Video/Audio Transmission
Links XL-2000/H, XL-2000/HP models

EXCELLENT MICROWAVE LINK 2.4 GHz WITH FREQUENCY AGILE CHANNELS

XL 2000/H is a portable microwave link built-in weatherproof Nema enclosures. It is frequency agile

in 2.4 GHz band. XL 2000/H is excellent solution for mobile applications and TV broadcast

transmission up to 16 km line-of-sight.

Installation and Operating Instructions

1• Verify proper operation of camera and monitor/event recorder using coaxial cable prior
to installing wireless link.
2• Install transmitter and receiver units in secure and dry place.
3• Install antennas above the enclosures.

USE EXTREME CARE WHEN INSTALLING ANTENNAS NEAR POWER LINES.
4• Tighten antenna cable to receiver and transmitter. Apply a small amount of silicone to
flange to make a leak proof connection.
5• Connect video, audio, power, cables to units through flanges. Tighten
flanges to allow small air gap at bottom of enclosure.
IMPORTANT NOTE:
Power adapter must be kept dry.
6• Verify that LEDs are lit up and transmitter and receiver are on same channel.
7• Tighten lid of enclosure down.

DO NOT APPLY POWER TO THE TRANSMITTER UNLESS THE ANTENNA IS
CONNECTED. PERMANENT DAMAGE MAY RESULT.

To obtain the best picture quality and transmission distance, the following rules of thumb
should be followed:

1) Mount the transmitter and receiver antennas above human and mechanical traffic,
the higher the better. A 10 foot (or more) steel mast on top of a building is typical. Make sure
that the mast is well grounded to earth ground with an 8 AWG or larger wire. For
maximum range, the transmit and receive antennas must be 15 to 30 feet above all
obstacles in the line of sight.

2) Keep the transmission path as open as possible

metallic objects near the transmission path may reduce the transmission distance.

. Objects such as walls and

3) Do not add additional lengths of cable to connect the receiver to the antenna as
significant losses in signal, and reduced transmission range will occur.

4

) Keep the cable connecting the antenna to the receiver as short as possible.

5) If needed you may run over 100 ft coax audio/video cable feed to the A/V source

IMPORTANT NOTE:
The Transmitter and Receiver units may get warm to the touch. This is normal
and does not affect operation in any way. Units are covered by one-year warranty.

WARRANTY VOID IF UNITS MODIFIED!

Figure 2 shows the front panel of the XL 2000/H transmitter and the functions of each control and

input/output. Each control is described in greater detail below.

IMPORTANT NOTE: The transmitter uses a non-standard (SMA) jack to connect to
the transmitter to antenna. Any modification to this jack may void the user’s
authority to operate the equipment and will void the manufacturer’s warranty.
AGAIN: DO NOT APPLY POWER TO THE TRANSMITTER WITHOUT THE
ANTENNA SECURELY ATTACHED- DAMAGE TO THE UNIT MAY RESULT.

VIDEO INPUT

Designed to mate to a standard BNC male connector, this input accepts 1 Volt peak-to­peak video in both NTSC and PAL formats. This input is terminated with 75 Ω.
RCA to BNC adapters are available for use with some cameras and VCRs.

AUDIO INPUTS

There are two separate audio inputs/outputs for stereo audio broadcast.
Designed to mate to a standard RCA male connector, this input accepts 300 milivolt peak-to­peak audio input and is terminated with 600 Ω unbalanced configuration.
It is designed to be interfaced to “lineout” audio sources. A preamplifier must be used to
connect a microphone to this input. RCA to BNC adapters are available for use with
some cameras and VCRs.

IMPORTANT NOTE:
With no video signal input, the transmit power level will be reduced in
compliance with FCC regulations, shortening the transmission range for audio
significantly. A video signal must be present on the video input
to allow transmission at full power.
POWER INPUT

Accepts a 12 Vdc power source such as the standard 12 Vdc adapters or an optional battery. The nominal
current draw is 280 milliamperes for the receiver part and 1.5 A for the transmitter part. If using an adapter
from a third party, use a well-regulated 12Vdc/500mA output supply for the receiver and 1.6 A/12 V well
regulated for the transmitter unit.

Changing Channels:

To change channels, simply depress the Toggle/Standby switch momentarily until the
LED for the desired channel pattern is lit up. Remember to change the receiver
channel as well, since it is not automatically changed when the transmitter channel is
changed. In order to change the channel please read the text bellow.

NOTE: MODEL XL-2000H/2 HAS SWITCH FOR THE TRANSMITTER INSIDE THE BOX. CAREFULLY OPEN THE
UNIT AND LOCATE SMALL PUSH-BUTTON SWITCH WITH LED DIODE. YOU CAN CHANGE THE CHANNEL
FROM 1-8. THE RECEIVE PART HAS A SWITCH WITH 8 CHANNELS- PLACE DESIRED CHANNEL TO ON
POSITION.

VIDEO OUTPUT

Designed to mate to a standard BNC male connector, this provides a 1 Volt peak-to-peak
video signal output. This must be terminated with 75 Ω. RCA to BNC adapters
are available for use with some monitors and VCR inputs.

AUDIO OUTPUT

Designed to mate to a standard RCA male connector, this provides a 1 Volt peak-topeak
audio output and should be terminated in a 600 Ω load, as is found in most “line
in” audio inputs. RCA to BNC adapters are available for use with some monitors and
VCR inputs.
