Æ Update Method Introduction
SM-100 use flash RAM instead of EPROM for the main program storage of the scale.
Before the boot program Version 1.10, we just have one method to update the scale’s
software: PC to scale via RS232 interface.
After the boot program Version 1.10 (including V1.10), we add a new method to update
the scale’s software: update the scale by ethernet. So you can choose either method
between these two ones to update your scale.
Now we will set two parts to introduce the steps of these two updating methods.
