Remote control

Important times for a command transmission:
To ensure secure data transfer, the time gap between two commands
should be at least 250 ms.
The circulator automatically responds to an
in
command with a data string
followed by an LF (Line Feed). The next command should be sent only
after 10 ms.
The
out
commands are valid only in remote control mode.
Examples:
When the RS485 interface is used, the three-digit instrument address
precedes each command.
(example: address Ad32 = A
0 3 2
)
