Serial ID Data and Descriptions
The Serial ID tables on the following pages contain specific information about the data contained within the
Serial ID EEPROM. Serial ID Table 1 on page 23 is a summary of all of the data fields in the Serial ID
EEPROM. Tables 2-6 contain translations of data words for each specific data field. Tables 7 and 8 list actual
Serial ID Data for the short wave and long wave products, respectively.
All ID information is stored in eight-bit parameters addressed from 00h to 7Fh. 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 character strings will
be padded on the right with ASCII spaces (20h) 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. CCID check code is the lower eight bits of the sum of the contents of
bytes 0-62. CCEX check code is the lower eight bits of the sum of the contents of bytes 64-94.
