This product is DiSEqC 1.x (one way DiSEqC) complaint.
The pages below assume some familiarity with DiSEqC concepts, for further reading please visit DiSEqC.org web site.
Every DiSEqC command issued is repeated 3 times, so cascading of slaves with the same address is not supported.
In this page DiSEqC core commands and user commands are defined.
Admin priviliges are required to access this page.
Users without admin priviliges will only be able to run the user defined commands.
The core commands page allows for support of additional layers of DiSEqC other than the default 1.1 and 1.2 layer.
It also allows changes to the addressing of the commands, which is defined as broadcast address by default.
Description
Displays a list of the core commands currently defined
Description
Creates a new command
Description
Edits an existing command
Description
Deletes an existing command
Description
Runs a command (for debug purposes)
Description
Resets all commands back to the original DiSEqC 1.1 and 1.2 factory default command set
The user commands page allows for user defined customization.
Each entry calls one of the basic command with a specific datum and LNB mode, and assigns a unique user defined name to it
So for example, if you have a SAR 212 Spaun switch, with one LNB connected to a dish pointed to London and the other to New York,
you can define a "London" Command that will issue a committed switch DiSEqC command with the datum 0xf0 (for input 1),
and a "New York" Command with the datum 0xf4 (for input 2), simplifying matters for the non-admin user.
For supported commands you may consult the user manual that arrived with your switch, or contact Novelsat post sale rep for support.
