How to use the RS-232C connector
This input/output connector (D-Sub 9-pin female) is used for
RS-232C external control.
A straight cable available on the market can be connected to
this connector to exercise external control and send status
information.
• Connector pin assignment
• RS232C Connection
The wiring requirements for a 9 pin to 9 pin serial
con nec tion, are a male to female straight cable.
• RS-232C physical specifi cations
• Command reception
The command packets have a data length of 7 - 10 bytes.
ASCII codes from 0x00 to 0x7f are used to receive serial
data. At the transmission end, therefore, take steps to
convert the ASCII codes into HEX data to set the data in
the data packets. CR (0x0d) is added as the data packet
delimiter.
