Runpost; Setup - Globalstar ST100 User Manual

8545-0194-01 v1.0

4.1.1.29. "runpost"

Run power on self-test (POST) for both the Nordic & Modem Processor.
Command:
Arguments:
Example:
Example response:
NOTE: If POST fails, the response will be: POST Failed w/ the flags value

4.1.1.30. "setup"

Command:
Arguments:
Example:
Example response:
NOTE: Factory default settings are: "setup 0 3 60 120"
Sending the command with no arguments returns the current settings. If sent with arguments, the response is the same,
confirming the settings.
All arguments must be present. If any are missing, or any are out of range, the command will return a fail message and reason.
The Channel Field: May contain 0 – 2 corresponding to simplex Return Link channels A – C respectively. Note that this will
affect the channel for the next raw transmission. Subsequent GPS fixes will steer the active channel to the appropriate one
based on GPS location.
The correct Globalstar Simplex channel is dictated by RAS (Radio Astronomy Site) avoidance and by a "geofrequency"
channel map. Whenever the ST100 board obtains a fix, it sets the channel based on these criteria. If a user uses the product
to send "raw" simplex messages without obtaining a fix, it is up to the user to be aware of where the device is and adhere
to this channel map. For example, Send Data (AA00) does not check for a GPS reading before transmitting data while Send
Redundant Burst with GPS (AA33) does. If AA00 is being used, the location should be checked regularly based on the
movement of the device before the data is sent to ensure the right channel is used. See document GS–07–1248 - REMOTE
TELEMETRY SERVICE FREQUENCY PLAN FOR SIMPLEX TRANSMITTERS to determine how to calculate the channel map.
The number of TX Tries field: Number of tries in the burst. Valid range is 1 – 5. If the number of TX Tries field is set to 1, the
message will have 0 retry messages.
Minimum time between tries: Based on a value from a legacy simplex transmitter (the original Globalstar STU), this is a number
of "5 second ticks". E. g. 60 = 5 minutes (5 * 5 seconds = 300 seconds). Minimum value = 1 (5 seconds) Maximum Value =
60 (5 minutes).
Maximum time between tries: Also, expressed in number of "5 second ticks". Minimum value = value of minimum time + 1.
Maximum value = 120 (600 seconds).
The wait between each "try" will be an evenly distributed pseudo-random amount of time between the minimum and maximum
value expressed above. Resolution of the pseudo-random timing for this device is 1.5 seconds.
