SERIAL Terminals Connection
The SERIAL terminal is used when this Display is controlled by
a computer.
Display No.1
[RS-232C]
NOTES:
• Use the RS-232C cross cable to connect the computer to
this Display.
• The computer shown is for example purposes only.
• Additional equipment and cables shown are not supplied
with this set.
Signal names for SERIAL IN terminal:
6 7 8 9
1 3 4 5 2
Pin No. Signal Name
1 DCD
2 RXD
3 TXD
4 DTR
5 GND
6 DSR
7 RTS
8 CTS
9 RI
These signal names are those of computer specications.
The SERIAL terminal conforms to the RS-232C interface
specication, so that this Display can be controlled by a
computer which is connected to this terminal.
The computer will require software which allows the sending
and receiving of control data which satises the conditions
given below. Use a computer application such as programming
language software. Refer to the documentation for the computer
application for details.
Communication parameters:
Signal level RS-232C compliant
Synchronization method Asynchronous
Baud rate 9600 bps
Parity None
Character length 8 bits
Stop bit 1 bit
Flow control -
Basic format for control data:
The transmission of control data from the computer starts with Header byte, followed by the command, the parameters, and
lastly byte of checksum in that order. If there are no parameters, then the parameter signal does not need to be sent.
Header MonitorID Category Code0 Code1 Length Control Data[0] Data[1] ~ Data[N] Checksum
0xA6 0~26 0x00 0x00 0x00 N+3 0x01
Command
Parameter The total from Header to Data[N] calculated by XOR
NOTES:
• Multiple commands are transmitted, be sure to wait for the response for the rst command to come from this unit before
sending the next command.
• If an incorrect command is sent by mistake, this unit will send an “ERROR” command back to the computer.
