RS-232C Adjustment
5.5.2 Interface
1) Connector
D-sub 9 pins (male/straight)
2)
Pin layout
3)
Baud Rate
9 600 bps (standard)
(switch-able to 1 200, 2 400, 4 800, 19 200, 38 400 bps)
Note
The baud rate of this display should be set to match the baud rate of the PC.
Also, when the RS-232C cable is extended over a long distance, use a slower baud rate.
4)

ETX (03 hex)
(2) Sending numerical direct commands:
STX (02 hex)
ID (2 Byte)
COMMAND (3 Byte)
ARGUMENT (3 Byte)
ETX (03 hex)
ID, COMMAND, ARGUMENT are transmitted as ASCII characters.
From the display to a PC
(1) Echo back (Normal response)
Command received and returned but the ID is not returned.
STX (02 hex)
COMMAND (3 Byte or 6 Byte)
ETX (03 hex)
Received command is a numerical direct effect command and numerical data is returned:
STX (02 hex)
COMMAND (3 Byte)
ARGUMENT (3 Byte)
ETX (03 hex)
(2) Error (Abnormal response)
Received command is a non-corresponding command,
‘
ERR
’
is returned:
STX (02 hex)
ERR (3 Byte)
ETX (03 hex)
Received command cannot be processed (when PON is received when the power is already ON, etc.),
‘
XXX
’
is
returned:
STX (02 hex)
XXX (3 Byte)
ETX (03 hex)
