SatelLink z USER MANUAL Remote Module PerCarrier De-Rating DCM000000052 All signals that fall within a given Pass-Band range will “share” power amongst them. A multiple channel effect is Intermodulation - signals produced from non-linear effects between the intended channel signals. This intermodulation may cause interference to receiving equipment. In order to minimize Intermodulation signals, Power de-rating must be applied.
SatelLink z USER MANUAL Operation DCM000000052 Normal Operation The LSU Head-End Module has one LED on the faceplate: 1. OPERATING - Normally this LED will be GREEN. The LSU Remote Module has three LED’s on the faceplate: 1. OPERATING - Normally this LED will be GREEN. 2. FAULT – Red LED, If the internal diagnostics for the module detect a problem, then this LED will remain on 3. LASERS ON - This LED will be GREEN when any one of the three Lasers are operating.
SatelLink z USER MANUAL Laser Safety Printed: 03.06.19,16:02 DCM000000052 • Both the Head-End and Remote Modules have Class IIIb Laser Devices as Fiber-Optic Transmitters. • Under normal installation both Modules are intrinsically-safe (Class I) since the Fiber-Optic cabling will be installed.
SatelLink z USER MANUAL Antenna Installation • • • DCM000000052 All Antenna Installation to be performed by Qualified Technical Personnel only. Antenna Installation Instructions and locations below are for the purpose of satisfying FCC RF Exposure Compliance requirements. The In-Building Antenna connection is via a coaxial cable distribution system with Signal Taps at various points connected to the fixed-mounted Indoor Antennae. This is shown in the figure in the Introduction.
