Command format and answer format
1.3
This unit shall be based on commands each of which consists of a data row ( some commands are without a PC ) composed of command codes ( CC ) and parameter codes ( PC ) . The trans-mitting station shall be designed to send block check characters ( BCC ) following ETX, with the data row enclosed in STX ( text start : 02h ) and ETX ( text termination : 03h ) . The receiving station shall regard receipt of BCC as the completion of command reception when it has received STX.
Here are the formats.
Commands : <STX> <CC> <PC0> <PC1> <PC2> <---------> <PCn> <ETX> <BCCH> <BCCL>
STX (Start of TeXt) : 02h CC (Command Code) : Command code PC (Parameter Code) : Defined for each command ( contents and number of parameters ) ETX (End of TeXt) : 03h BCC (Block Check Character) : CC + PC0 + PC1 + PC2 + --------------- + PCn + ETX = XYh (Each of X and Y is 4 bit long ) X , Y=0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F BCCH ( high-level byte ) = X as converted to an ASCII code BCCL ( low-level byte ) = Y as converted to an ASCII code
Answers : <STX> <RC> <AC> <PC0> <PC1> <PC2> <--------> <PCn> <ETX> <BCCH> <BCCL>
STX (Start of TeXt) : 02h RC (Reply Code) : Reply code (=Command code) AC (Answer Code) : Answer code PC (Parameter Code) : Defined for each command ( contents and number of parameters ) ETX (End of TeXt) : 03h BCC (Block Check Character) : RC +AC + PC0 + PC1 + PC2 + ------------- + PCn + ETX = XYh (Each of X and Y is 4 bit long) X , Y=0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F BCCH ( high-level byte ) = X as converted to an ASCII code BCCL ( low-level byte ) = Y as converted to an ASCII code
Protocol for data transmission and reception
1.4
This unit is based on half-duplex communication. The unit shall therefore transmit commands and receive answers according to the following procedure.
1.4.1
1)
2)
3)
Basic procedure
The host shall select commands for this unit and transmit them to this unit. Command
interval time is MIN 40µsec.
Having issued a command, the host shall receive an answer from this unit, then issue
the next command.
The host shall analyze the RC, AC, and PC as answers given and decide whether the

command has been normally executed.
The host shall give an answer to a command that gives operational instructions, then
4)
issue a status request command, and decide whether this unit has finished operating with regard to the command that gives operational instructions.
The time from the start of command transmission to the end of command transmission
5)
should be max 40 msec.
The time from the completion of command transmission to the start of answer-back is
6)
MAX.60 m
This unit cannot receive any commands for about 5 seconds after the power switch is
7)
turnied on.
5sec.

2)
3)
4)
5)
Communication errors
Having received a command, which results in a communication error ( overrun, framing, or parity error ) , this unit shall give NAK ( 15h ) . ( MAX 80ms from the start of command transmission )
If the host has received NAK from this unit, it shall retransmit the command that it has transmitted immediately beforehand.
Having received an answer, which results in a communication error ( overrun, framing, or parity error ) , the host shall respond with NAK.
If it has received NAK from the host, this unit shall retransmit the answer it has transmitted immediately beforehand. ( MAX 40ms)
When there is no answer from the unit within 80 m command.
6s, the host shall retransmit the
