The OTx has been designed to be either externally mounted i.e directly onto the pole
behind a dish (using the supplied mounting bracket) or internally on a wall / in a cabinet.
Please refer to diagram typical topology for example system.
Fibre Connection
• Cleantheoutputbreopticalconnector
and check the optical power using a
suitable optical power meter.
Optical power out of the OTx should
be +7dBm 0.5dB.
• Clean the optical connecter and make
a connection to the optical output of the
OTx, ensuring the keyway is aligned.
• Important - The gel boot supplied should
be clipped around the FC/UPC connector
to ensure weather protection. Performance

• Fibre cable should be singlemode and
should be suitable for the environment

Powering
• The OTx can be directly powered on the F connector power input using a 20V PSU
(DVE DSA-40CA-19 200120) with the Jack to F adapter.
• The mains adapter is the disconnect device for the unit. Please ensure it is easily accessible.
• LED on the OTx is to indicate correct powering of unit. The LED should be a constant green.
• Maximum current draw 350mA excluding current on connected inputs.
Coaxial connections
• Ports labelled V or H should be
connected to a suitable wideband LNB
(recommended D000430) ensuring
correct polarisations are connected
to the relevant ports.
• Voltage is supplied for LNB powering.
V = 12V, H = 20V. Maximum current
500mA inc terrestrial.
• Port labelled FM/DAB/DTT input should
be connected to your terrestrial
antennas using an appropriate
combiner.Signalsshouldbeltered
and levelled for optimum performance.
• Voltage supplied on terrestrial input is
12Vforpoweringamastheadamplier.
• If terrestrial input is connected to a
device not rated for a voltage, then a
DC block should be installed between
the OTx and the device.
