SAGEM-LINK F
Installation and Operation Manual
To change T/R spacing in this frequency plan, it is necessary to apply to following procedure. The T/R
spacing change is made separately on each terminal, with the Pilot software in super user mode. Two
cases are considered : 119 MHz
To make this change, it is necessary to have the IDU connected to its ODU.
1- Procedure for changing T/R spacing from 119 MHz to 126 MHz
• Connect the PC to the local IDU and run the Pilot software in super user mode
• Mute the local terminal
• Decrease capacity or change modulation (QPSK : max = 8x2 Mbit/s)
• If necessary change Transmit frequency to the wanted frequency
• Go to the menu Parameters/Read ODU Parameters Local
• Change Tx-Rx Spacing to 126 MHz and validate with the OK button
• Unmute the terminal
• Switch off then switch on the terminal
• Connect the PC to the remote IDU and run the Pilot software in super user mode
• Use the same procedure as per the local terminal
• Once all the changes have been made, the link should be established with the new T/R spacing
2- Procedure for changing T/R spacing from 126 MHz to 119 MHz
• Connect the PC to the local IDU and run the Pilot software in super user mode
• Mute the local terminal
• If necessary change Transmit frequency to the wanted frequency
• Change Tx-Rx Spacing to 119 MHz and validate with the OK button
• Increase capacity or change modulation
• Go to the menu Parameters/Read ODU Parameters Local
• Unmute the terminal
• Switch off then switch on the terminal
• Connect the PC to the remote IDU and run the Pilot software in super user mode
• Use the same procedure as per the local terminal
• Once all the changes have been made, the link should be established with the new T/R spacing
