Synchronization

During data communication between
the moisture analyzer and an on-line
device (computer), messages consisting
of ASCII characters are transmitted via
the interface.  For error-free data com-
munication, the parameters for baud
rate, parity, handshake mode and
character format must be the same for
both units.

You can adapt your moisture analyzer
by setting corresponding parameters in
the Setup menu.

If you do not connect a peripheral
device to the analyzer’s interface port,
this will not generate an error message.

Handshake

The moisture analyzer SBI interface
(Sartorius Balance Interface) has
transmit and receive buffers.  You can
define the handshake parameter in 
the Setup menu:

– Hardware handshake (CTS/DTR)
– Software handshake (XON, XOFF)

Hardware Handshake

With a hardware handshake, 1 more
character can be transmitted after CTS
(“clear to send”).

Software Handshake

The software handshake is controlled
via XON and XOFF.  When a device is
switched on, XON must be transmitted
to enable any connected device to
communicate.

When the software handshake is
configured in the Setup menu, the
hardware handshake becomes active
after the software handshake.

The data transmission sequence 
is as follows:

Moisture

__ byte __> Computer

analyzer

__ byte __> (receiving

(transmitting

__ byte __>

device)

device)

__ byte __>

<__ XOFF __

__ byte __>

__ byte __>

…

(Pause)

…

<–– XON ––

__ byte __>

__ byte __>

__ byte __>

__ byte __>

Transmitting Device:

Once XOFF has been received, it pre-
vents further transmission of characters.
When XON is received, it re-enables 
the transmitting device to send data.

Receiving Device:

To prevent too many control commands
from being received at one time, XON 
is not transmitted until the buffer is
almost empty.

Activating Data Output

You can define the data output para-
meter so that output is activated either
when a print command is received, or
automatically and synchronously with
the analyzer display.

Data Output by Print Command

The print command can be transmitted
by pressing 

r

or by sending a

software command (Esc P).
