Connect radiators
The transmitter has six BNC HF Output connectors labeled 1, 2, 3, 4, 5 and 6 on the rear
panel. All six outputs are functionally identical. They can each drive up to 30 radiators
(LBB 4511/00 and/or LBB 4512/00) in a loop‑through configuration. The radiators are
connected with RG59 cables. The maximum cable length per output is 900 m (2970 ft) to the
last radiator. Automatic cable termination is achieved by a built-in switch in the BNC
connectors on the radiator.
Figure 6.5: Loop-through connection of radiators
Notice!
For the automatic cable termination to work, never leave an open-ended cable connected to
the last radiator in a loop-through chain.
When connecting infrared radiators, do not split the cable, else the system will not function
correctly.
Analog IR radiators LBB 3510/05, LBB 3511/00, and LBB 3512/00 can be used with Integrus,
with the following limitations:
– Not more than the first 4 carriers can be transmitted.
– Not more than 100 m cable length from transmitter to last radiator.
– Directly connection of the radiators to the transmitter with equal cable length. In
loopthrough connection, the total cable length from the first to the last radiator may not
exceed 5 meters. Reason: there are no facilities on this radiator for compensating the
cable signal delay.
