RF-Link Technology XL-2000/H 사용자 설명서
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.

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-to-
peak video in both NTSC and PAL formats. This input is terminated with 75
input/output. Each control is described in greater detail below.

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-to-
peak 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.
