SELECTCHANCONFIG

Sets the channel configuration

Platform:

OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2

SELECTCHANCONFIG selects which channel configuration (set of GNSS signals to be tracked) is to be used from those made available by the active software model and as listed in the CHANCONFIGLIST log. Subscription Managed Channel Configuration (SMCC) will override this selection (see Receiver Features: Authorization and Subscriptions) when TERRASTARAUTOCHANCONFIG is enabled and a TerraStar subscription supporting SMCC is active. In that case, the SELECTCHANCONFIG command will be rejected. The CHANCONFIGLIST log SetInUse parameter indicates which configuration is currently active.

Issuing a SELECTCHANCONFIG command immediately reboots the receiver into the new configuration. The SELECTCHANCONFIG setting is reset to default when the selected permanent model changes.

The factory default value depends on the active software model.

  2. There are nine options given for the model and the fifth channel configuration set is currently being used.

  3. If the user would like to use the third channel configuration set enter, SELECTCHANCONFIG 3 command.

  4. The receiver receives the command and resets. At startup, the third channel configuration set is configured.

  5. To verify that setting has changed, enter LOG CHANCONFIGLIST.
