Communication
The following chart shows the flow of data between the PC and the SERVO
STAR
CD-Lite. When logic
power is applied to the drive, it loads the variable parameters stored in EEPROM into the dynamic RAM
for fast and easy access. You can read (and write) these variable parameters to (and from) the PC by one
of several methods described in the INITIAL
STAR
TUP section below.

Memory Flow Chart
The PC transmits serial data to the drive and stores it in dynamic RAM. However, any variable data
changed from the PC is lost when logic power is lost, if it is not saved into non-volatile EEPROM. If you
configure the same system on similar applications, the variables can be saved on disk in an .SSV file for
convenient downloading into other drives
