• An inner cable conductor
diameter greater than 1.2 mm,
or the presence of burrs may
damage the sockets on the
unit.
When using the UAS 585 switchable LNB or a multi-switch with a current consumption of more than 40 mA
per subscriber, the EXR 221 must be locally fed using the NCF 18 power supply unit.
The EBC 110 should be used as the splitter. The necessary diode protection is provided by the sockets ESU 33
and 34.
Particular care should be taken to assign each of the frequencies available at the output from the multi-
switch to only a single receiver, otherwise the receivers will generate mutual interference. The frequencies are
assigned in the receiver's setting menu. Depending on the type, this assignment may be manual or automatic.
By defi nition the system is designed so that single-cable devices are supplied with 14 V DC. The power
supply is brie
fl
y switched to 18 V DC if control signals similar to DiSEqC™ have to be transmitted. Continuous
application of 18 V would block the system. For this reason we recommend the use of ESU 33/34 sockets,
which are equipped for switching off electronically.
The receivers that are connected must be designed for single-cable operation to EN 50494
