2) Configure the Transmitter parameters as shown in the following table.
Parameter
Description
Auto Start
 ON
 Off
 Traffic
Specific for the transmitter. When set to "traffic", the VSAT will log on to the Hub when
it has traffic to send. After a configurable time (given by Timeout) without any traffic to
send, the VSAT will automatically log off.
EIRP (dBW)
Specifies the emitted power level. Only used for a SatLink 403x ODU and not relevant
for a 3rd party BUC.
Timeout (min)
Idle time before the VSAT automatically logs off when the Autostart mode is set to
"traffic".
IDU OutPow (dBm)
Only used for 3rd party BUCs, as the IDU output power is set automatically when using
a SatLink 403x ODU.
BUC
Specifies the BUC type or transceiver type with which the VSAT is equipped. The valid
ODU transmitters (BUCs) are listed in Table 9.
Antenna
Specifies the antenna type with which the VSAT is equipped. The correct antenna type is
required to correctly compute EIRP used for the automatic power calibration of the
SatLink 403x transceiver. The valid ODU receivers (LNB) are listed in Table 11.
If the ODU transmitter type or LNB type has been changed, the VSAT must be restarted to
activate the new configuration (press the Restart button after saving the configuration).
3) Click the Save button to save the configuration.
4) Click Start button to start the transmitter manually (only required with Autostart mode ―off‖).
6.2.3 VSAT Positioning
The Operator must specify the geographical position of the VSAT to enable the VSAT to log on to the
network. In order to calculate the delay to the satellite correctly for the logon burst, the VSAT must be
configured with its own geographical position. Find the position of the location where installing the
VSAT using a standard GPS.
The VSAT position is entered in the below format:
 degrees, minutes, seconds, and direction
