Data transfer

3.1

RS-232-C Interfaces

®
The AVS 370 has two RS-232 C interfaces. Interface 1 is used to communicate with the computer;
interface 2 is used to connect to another viscosity meter AVS
®
AVS 350/360.
Connection between more than one AVS
To establish the data transfer between more than one AVS

Make a RS-232-C connection from the computer to interface 1 of the first device.

Then use another cable to make a connection from interface 2 of the first device to interface
1 of the second device.
The device address of the second connection viscosity measuring device AVS
different from the address of the first viscosity measuring device AVS
be moved on the second device when connecting a second AVS
service (backside of these operating manual).
If burettes are used, these can be connected to interface 2 of the second AVS 370 via an
RS-232-C cable.
3.2

Interface configuration

The interface parameters cannot be changed! All transmission parameters are firmly set to the
following values:
Baud rate
Parity
Stop bits
Data bits
All other devices to be connected (burettes, AVS
settings.
3.3

Connetion to a USB port on the PC

®
The AVS 370 can also be connected to a USB port on the computer if suitable adapters are used
USB serial. We recommend the adapter USB-RS232 TZ 3080.
This adapter is part of the delivery scope of the AVS
3.4

Device address

In order for the devices to be addressed by the software, you need unique addresses.
The communication protocol used allows the addressing of 16 devices.
The addresses used are 0 to 15.
3.4.1 Automatic address assignment with the AVS
®
Within an AVS 370 module, the ViscoPump inserts are automatically populated based on their
positions at the addresses 1 (first slot) to 4 (fourth slot).
When using an additional AVS
that the addresses 5 to 8 are allocated in this module.
All other sizes (burettes, AVS
Please check the instructions for use of the respective devices.
The WinVisco software expects viscosity measurement devices in the address zone 1 to 8 (ViscoPump,
® ®
AVS 350, AVS 360). Burettes are expected in the address range 9 to 15 and at address 0.
