5 Operating the VSAT system
Once the Antenna and ACU have been installed safely and all the system cabling is connected, you can
power-on the system. Please refer to the power supply requirements of this document to check the
requirements. If there is already a pre-configured satellite, after powering-on the antenna will automatically
adjust all its parameters (sensor, gyro, elevation, skew etc) and lock onto the satellite automatically. However,
the user can also easily configure the desired parameters from the ACU's web-interface.
The ACU has to be mounted into a standard 19-inch rack. All EPAK VSAT systems provide a web interface for
basic monitoring and configuration, which can be accessed by connecting to any one of its LAN interfaces.
Therefore, it is recommended to mount the ACU where the antenna status can be checked.
The ACU is connected to the ODU via 2 coaxial cables RX and TX. The RX cable carries the receive signal in
IF, and the DC power supply for the antenna. The TX cable carries the transmit signal in IF, reference signal
for the BUC and power for the BUC.
The ACU is connected via two coaxial cables (RX & TX) and one Ethernet cable to the satellite modem. The
ACU forwards the IP traffic from the modem to its own LAN interfaces.
You can also connect the ship's compass to the NMEA interface of the ACU for accurate heading information.
This heading information is optional, so if it is not connected,the antenna relies on the heading data obtained
from the GPS receiver fixed to the antenna.
Please check the description given below for a short overview of the key functions of the ACU.
