Important notes for using the devices
3.1
FO-TX 2-EC and FO-TX 2-OPT
The transmitters can be powered by 240 V
housing. The three powering sources and the transmitter´s battery status will be
transmitted via both fibre channels.
3.1.1 Powering by DC using a 4-pin XLR socket
•
The DC power supply unit is not included in the delivery.
•
When wiring a 4-pin female XLR to a DC supply, pin 1 to ground and pin 4 to
+12 V
. The pins 2 and 3 will not be connected (see also on page 8).
DC
3.1.2 Powering by V-lock battery
•
The battery is not incluced in the delivery
•
The transmitter does not charge the battery, for charging it must be removed.
•
The battery can be installed alongside another power source as a backup.
3.1.3 RF input powering
An internal switchable bias-T will provide 12 V/200 mA to the antenna inputs for
powering head amplifiers such as the AB 1036 antenna booster.
3.1.4 Exchanging the optical outputs
For the optical outputs, the unit can be supplied with a Neutrik Opticalcon DUO
socket or two E2000-APC sockets. These can be exchanged in the field by suitable
qualified personnel.
3.2
FO-RX2-EC
•
Supply the receiver with the Sennheiser NT 1-1 power supply unit only.
•
The two DC jack sockets are wired in parallel and are interchangeable.
•
Use the supported DC link cable for powering the ASA 1 active antenna splitter.
ATTENTION!
Damage of the receiver!
Voltages of more than 16 V
DC
not exposed to an excessive bias voltage from the input of the equipment they are connected to.
•
The two laser light level bargraph displays indicate the level of the light signal
received down fibre channels A and B (not the RF level transmitted on that
channel). A low laser level may degrade the output RF signal, however, as there
are many other factors affecting the performance of the connected equipment,
there is no definite threshold level for operation. Rather, these indicators should
be used as fault finding tools.
•
The other bargraph display indicates the status of the battery, and the LEDs
indicate the presence of the three possible power sources. In the absence of this
information from a connected FO-TX 2-EC, the LEDs will flash in sequence. As this
information is transmitted down both fibre channels, you may select which
channel is used by the front display, using the internal data select A/B switch.
This will not be necessary in normal operation.

may irreparably damage the receiver. Ensure that the RF outputs are
