Overview
The Norsat Universal LNB Controller (ULC) is a standalone control unit for a single multi-band LNB. This system allows a user to select LNB frequency bands without any additional control hardware. The ULC can be configured to fit most applications and has options for:
· RF Connector customization · 10MHz reference configurations · Line Length Compensation (LLC) to compensate for voltage drop between the ULC and LNB · Control Interface customization
System Overview
The ULC system consist of a ULC, universal power supply, and mounting plate. When powered on, the unit supplies a variable voltage and tone control signal to a multiband LNB, supporting up to quad-band applications. The ULC is installed between the Modem and LNB as shown in the diagram below.

Control Interface Cable For the Control Interface Cable option, the control switch is replaced with a 4-pin connector (see image below). With this option, the ULC can be controlled by applying a voltage to the control pins (see tables below). A mechanical diagram of the control pinout is shown below. Note: It is the user's responsibility to determine how to drive the control pins on the ULC. With the provided 2m long cable, the ULC can be connected to control hardware such as a PLC, Microcontroller, Ethernet I/O module, or other programmable logic device.

System Troubleshooting

PROBLEM No power to the LNB
LNB not switching frequency bands

TROUBLESHOTING STEPS
1. Verify that the ULC power supply is connected to AC power. 2. Verify that the LNB is connected to the "LNB" RF connector and
not the "Modem" RF connector. 3. Verify that the LNB RF cable is threaded properly on the ULC. 4. Swap LNBs to determine if the LNB is malfunctioning. 5. If the problem is not corrected in the above steps, contact the
manufacturer. 1. Verify that the control interface is set properly (See Section 3.5) 2. Verify that the LNB is connected to the "LNB" RF connector and
not the "Modem" RF connector. 3. Verify that the multiband LNB is compatible with the voltage and
tone control provided by the ULC. 4. Power cycle the ULC 5. If the problem is not corrected in the above steps, contact the
manufacturer.
