2. Terminal Identification
This sections provides information on terminal identification numbers and where to locate them.
2.1 Serial Number Definition
Serial Number (SN) = Model code + Sequence number
If the length of SN = 8, 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, then the length of Model Code = 3 and contains ASCII(0 ~ 9), the length of the
Sequence number = 7 and contains ASCII(0 ~ 9).
