HD- ACU and multi-switch for DirecTV
The installation shown above uses an HD-ACU and a multi-switch. However, to be able to track three DirecTV satellites and have the
ability to change channels using DiSEqC, you will need to purchase and install a DiSEqC Supplier - Raymarine Part No. A90614. For
full details of using DiSEqC to switch satellites refer to “Satellite switching”.
To connect a multi-switch and DiSEqC Supplier:
1. Connect a 15 m RF cable between Antenna RF1 of the HD-ACU and RF1 on the antenna baseplate.
