If you are reusing the same DiSEqC 1.2 Motor Number assignment, for both C and KU satellites, the dish must either be at the correct location when the number is reused, or the ASC1 power must be OFF (or in Standby). Failure to either power OFF the ASC1 or to have the dish the correct position (motor count) when pressing DiSEqC 1.2 Position Number "Save" on the Linkbox for a second satellite, will overwrite the ASC1's original dish count position with the current dish position. This is the way that all DiSEqC 1.2 motor controllers work.
Example: Intelsat 21 C-band is saved as DiSEqC 1.2 Motor Assignment #1 in the Linkbox and the ASC1 shows 001 on the top line and Position: 0000 count on the second line. To save the same motor assignment # 001 for Intelsat 21 KU-band the ASC1 must be either powered OFF to prevent the Position: 0000 count to be overwritten with the current dish count position or the dish must be positioned at count 0000 when saving DiSEqC 1.2 Motor Position Assignment Number #001.
A DiSEqC 1.2 Motor Assignment Number is correctly saved by the Linkbox when the Linkbox and the ASC1 shows the same motor number assignment. The ASC1 will show the motor assignment number on the top line with the corresponding Position Count Number on the 2nd line.
Once the satellites are programmed by the Linkbox to both Linkbox and the ASC1, then the satellite selection is made with the Linkbox. If you are watching TV, just change channels and if the next selected channel is on another satellite, the Linkbox tells the ASC1 what motor assignment number and the polarity. The ASC1 remembers what dish position count you saved and drives the dish to the correct position count number and sends the correct volatge to the LNBF to select the correct polarity.
If you are in any Linkbox menu or list, just select the desired channel, satellite or transponder. The Linkbox sees your selection and tells the ASC1 what motor assignment number and the polarity. The ASC1 remembers what dish position count you previously saved and drives the dish to the correct position count number and sends the correct voltage to the LNBF to select the correct polarity. Doesn't matter if you are scanning for new channels, channel surfing, toggling through a chanel list or adjusting an installation screen parameter, the Linkbox automatically tells the ASC1 what satellite or polarity that you have selected. No need to go into the DISEqC 1.2 sub menu unless you wish to change a motor parameter like position or assignment number.
A conflict will occur if the Linkbox is tuned to one satellite and you select manually select a different satellite on the ASC1. The Linkbox will see that the tuned signal is lost and automatically start sending commands to the ASC1 to try and reacquire the selected satellite. This will cause the ASC1 tyo move back to the satellite that is selected on the Linkbox. You can manually bump the motor position and or resave using the ASC1 remote or front panel, but the Linkbox is in control of the satellite selection.
Note: The ASC1 navigation arrow (on the left side of the display) should not be parked on Horizontal or Vertical polarity as this selection will manually override the Linkbox's polarity selection.
At this point it is probably best to perform a global reset on the ASC1 with the position count where you want to reference 0000. It would also be best practice to perform a factory reset on the Linkbox to reset any incorrect motor assignments and other settings that might have been set during the programming and aiming attempts.
