satbackup b bt g gt o

Sets the option to switch to a backup satellite modem if the cellular network?s coverage is poor.

The satellite modem power must be driven by a modem output for this feature to work.

The user defines the RSSI(receive signal strength) threshold to initiate the switchover, the timeouts and the output number to use.

When the RSSI value falls below the bad RSSI threshold for a certain timeout period, an output will be set.

When the RSSI value rises above or equal to the good RSSI threshold for a certain timeout period, an output will be cleared.

Notes:

• This command is only available on data cards/modules that provide RSSI information to the modem. Contact Cypress Solutions for a complete line of

supported data devices

b = -1 to -125 Bad RSSI threshold in dBm; requires the negative sign (0 disable)

bt = 0 to 65535

Bad RSSI timeout in seconds; if the RSSI is less than the bad threshold for

the timeout period, than set the output.

g = -1 to -125 Good RSSI threshold in dBm; requires the negative sign (0 disable)

gt = 0 to 65535

Good RSSI timeout in seconds; if the RSSI is greater than or equal to the

good threshold for the timeout period than clear the output.

o = 1 to 4 Output number. (Default 1)

o = 5 Output on DSR on port 1

Examples:

1. Set the bad RSSI threshold to -100dBm with a timeout of 30 seconds; set the good RSSI threshold to -95dBm with a timeout of 30 second; trigger

output 2 :

cmd satbackup -100 30 -95 30 2
