A2. Serial Number Definition
If the length of SN = 8 digits, then the length of Model Code = 2 and contains ASCII(0 ~ 9 & A ~ Z, but
without O & I), the length of the Sequence number = 6 and contains ASCII(0 ~ 9).
If the length of SN = 10 digits, then the length of Model Code = 3 and contains ASCII(0 ~ 9), the length of
the Sequence number = 7 and contains ASCII(0 ~ 9).
When a Product has had more devices manufactured than can be supported by its number of digits, a
new model number will be established.
Example:
1. D180 SN# 64999999 evolved to 6A000001
2. SP30 SN# 30999999 evolved to 3A000001
