Serial ID Data Descriptions (Page/Device Address 0xA0)
All ID information is stored in eight-bit parameters addressed from 0x00 to 0x7F. All numeric information
fields have the lowest address in the memory space storing the highest order byte. The highest order bit is
always transmitted first. All numeric fields will be padded on the left with zeros. All character strings are
ordered with the first character to be displayed located in the lowest address of the memory space. All char-
acter strings will be padded on the right with ASCII spaces (0x20) to fill empty bytes.
Check Codes
The check codes contained within the identification data are one byte codes that can be used to verify that
the data in previous addresses is valid. CC_BASE check code is the lower eight bits of the sum of the con-
tents of bytes 0-62. CC_EXT check code is the lower eight bits of the sum of the contents of bytes 64-94.
