Lassen SQ GPS Receiver 5 3
Operation and Performance 4
A hard reset is a system restart that results in satellite acquisition
search using a default search set. Any data contained within RAM
memory is discarded and the real-time clock is re-initialized. Even if
back-up power is supplied, the information from memory and the real-
time clock is not used. There are two ways to initiate a soft reset:
•
Issuing the 0x1E command with a value of 0x4B.
•
Cycling power without back-up power applied. Using this
method, power must be removed for at least 3 minutes to ensure
any residual memory storage is erased. If power is cycled
rapidly, the 0x1E command with a value of 0x4B must then be
issued to the receiver 2.5 seconds after power is restored to
ensure a hard reset.
A factory reset is used to restore all the factory default settings into the
receiver. Any user settings stored in Flash memory will be erased.
Issuing the 0x1E command with a value of 0x46 will initiate a factory
reset.
