1.175 SFALMENABLENEW
SF-3050 Sapphire SF-3040
This is a one-time user command that allows the end-user to manual switch-over and enable a
new over-the-air StarFire Almanac that has been received.
This command is intended to be used in conjunction with [SETSFALMWITCHMODE] set to
MANUAL mode, and real-time indication from the [NEWSFALMREADY] output message that a
new StarFire Almanac has been received that’s different than the current one in-use. The
receiver will continue to use its local StarFire Almanac and not switch over to the new StarFire
Almanac until this command is sent by the user. This is particularly useful if the receiver is in the
middle of a critical operation and the user doesn’t want any updates to almanac until the
operation is completed.
The receiver will only accept this command when:
1. [SETSFALMSWITCHMODE] is set to MANUAL mode. Command is rejected in
AUTO mode.
2. A valid StarFire Almanac has been received and is different (e.g. frequency change)
than the current almanac that the receiver is using.
Otherwise, the command is invalid and will be rejected, unless these three conditions are met.
This command is issued with no parameters.
