If the circulator is put into remote control mode via the configuration level, the
display will read "r OFF" = REMOTE STOP.
The circulator is now operated via the computer.
In general, the computer (master) sends commands to the circulator (slave). The
circulator sends data (including error messages) only when the computer sends a
query.
A transfer sequence consists of:
• address (RS485 interface only)
• command
• space (⇔ Hex: 20)
• parameter (the character separating decimals in a group is the period)
• end of file (↵; Hex: 0D)
The commands are divided into
in or out commands.
in commands: asking for parameters to be displayed
out commands:
setting parameters

The
out commands are valid only in remote control mode.
When the RS485 interface is used, the three-digit instrument address stands in
front of each command.
(example: address Ad32 = A
032)
