7. How to use the communication interface
Precautions when preparing a communication program
Be sure to check the parameters in the communication specifications and the
specifications of the PC to use.
The host shall append delimiters (<CR> <LF>) at the end of a command to send.
Since any commands other than the terminal command shall be sent/received in
principle and sending or receiving by character strings will cause a hang-up.
BF500 always appends an ID prompt (example:01>) at the end of data when sending
it. The host shall regard one communication session has completed when it receives
an ID prompt not delimiters (<CR> <LF>).
Communication data for this interface is in the ASCII format without exceptions.
A remote target temperature and a remote pump speed level shall be set before
issuing a remote operation start command.
When the standard communication interface of your PC is RS-232C only, use our
optional RS-
422A converter “RC-23”. And use our optional cable for connection
between your PC and BF500 and between two or more BF500 units.
Chack that power for BF500, your PC and the converter are OFF before connecting a
cable.
