Communication control ordering
1. The communication control ordering of TZ/TZN Series is
exclusive protocol.
2. After 4sec. being supplied the power into master system,
then able to start communicating.
3. Initial communication will be started by master system.
When Command signal comes out from master system
then TZ/TZN Series will respond.

① Start code
It indicates the first of Block STX → [02H],
in case of response, ACK will be added.
② Address code
This code is master system can discern TZ/TZN Series
and able to set within range of 01 to 99.(BCD ASCII)

③ Header code:
It indicates command as 2 alphabets as below.
RX(Read request) →
RD(Read response) → R[52H], D[44H]
WX(Write request) →
WD(Write response) → W[57H], D[44H]
④ Text: It indicates the detail contents of Command/
Response. (see command)
⑤ END code: It indicates the end of Block. ETX → [03H]
⑥ BCC: It indicates XOR operating value from the first to
ETX of the protocol as abbreviation of TZ/TZN.
