LVH-6 VIDEO SWITCH
AUTOMATIC VIDEO SWITCH 2:1
The LVH-6 was designed to switch video signals from two sources to one output. The unit
utilizes a high quality RF relay to automatically switch to an alternate source when the
primary signal is lost. The slave output allows for controlling other units. Power connections
are made using block terminals. The unit responds to NTSC and PAL signals.
SAFETY INSTRUCTIONS
• Before your initial start-up, please make sure that there are no transport damages. Should
there be any, do not take the device into operation and immediately consult your dealer.
• Operate the device only after having familiarized with its functions. Do not permit operation
by persons not qualified for operating the device.
• Protect the device against humidity and heat. Keep away from heaters and other
heating sources!
• We recommend a frequent cleaning of the device. Disconnect from mains first. Use
a soft lint-free and moistened cloth. Never use alcohol or solvents!
• There are no serviceable parts inside the device. Maintenance and service operations are
only to be carried out by authorized dealers.
• Damage, caused by manual modifications on the device are not subject to warranty. If the
device is used for other purposes than originally intended or if it is not correctly connected,
the product may suffer damages and the guarantee becomes void.
• This product is allowed to be operated with 12-24 V DC. This device falls under protection
class 3 and was designed for indoor use only.
OPERATION
Prior to connecting switch off all units and do not turn them on again until you have made all
necessary connections.
1 Connect your signal source via a 75 coaxial cable with BNC plugs to the jack INPUT.This
input is 75 terminated.
2 Connect an alternative signal source via a 75 coaxial cable with BNC plugs to the jack
AUX INPUT.This input is terminated when it is connected to the output and is unterminated
when it is not in use.
3 Connect the unit to which the video signal is to be switched via a 75 coaxial cable with
BNC plugs to the jack OUTPUT. The output is designed to connect to a 75 load.
4 To power the unit 12-24 V DC are required. For this purpose, connect a power source (e.g.
power supply unit, battery) to the terminals DC 12-24. Always observe the correct
polarity.Connect the marked core to the left contact "+".
5 To control another unit with the LVH-6 connect it to the terminal SLAVE.
6 When the LVH-6 detects a video signal the jack INPUT is connected to the jack OUTPUT.
The unit responds to valid NTSC or PAL sync while ignoring 50 Hz and 60 Hz hum related
to induction artifacts. Weak signals as low as 0.5 V can be detected. When a valid signal is
detected, the relay also provides a ground connection to the SLAVE terminal, permitting
the unit to be connected as a video presence detector.
7 In the absence of video input at the jack INPUT or if power to the unit is interrupted, the jack
AUX INPUTis connected to the jack OUTPUT.
