Chapter
 Data Ln=1(Fixed)
Slot#=0, Index 253: read FW revision
Data Ln=4(Fixed for STXPBS001), 1(all-in-one modules)
 Slot#=254: read user data from EEPROM user area
Index=0~127(Offset in EEPROM user area)
Data Ln=Length for data to be read
The following screenshot displays the terminator resistor specification.
In order to minimize cable reflections and ensure a defined noise level on the data lines,
the data transfer cable must be terminated at both ends with a terminating resister
combination as follows:
