Hello, everyone. Somebody faced with operation of the Intellian V-1205 Global PLL Ku-band.   The PLL LNB will operate over the following standard LO Frequencies 9.75, 10.0, 10.25, 10.5, 10.6, 10.678, 10.7, 10.75, 10.8, 11.0, 11.05, 11.2, 11.25 and 11.3 GHz, as well as any special dedicated frequencies, ensuring future proof operation, and allowing the operator to fine-tune LOs to maximize performance for their specific environment.
How does it work?

Hello there Willtek,

This is process to set LO frequency
Using the Intellian DISEqC communication ACU, select the LNB type.(i.e. type O, type R etc.). The ACU sends a message to the NBD/FSK board to set the LNB type. In “Another” mode, the ACU sends a message to the NBD/FSK board including LO set by a customer. The LNB is set the type according to the type table in the MPU which is PLL circuit in the LNB. The customer can use like SMW LNB with common DISEqC. (i.e. 13V, 18V, 13V+22KHz, 18V+22KHz). Hope this helps?
