Data transfer

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
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 connected AVS
®
first viscosity AVS
370. Therefore, a jumper must be moved on the second device when connecting a
®
second AVS
370 device. Please contact the service (backside of these operating manual).
If burettes are used, these can be connected to interface 2 of the 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 (especially burettes for rinsing) must have the same parameter
settings.
3.3
Connection 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.
Automatic address assignment with the AVS
3.4.1
®
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.
The addresses of the other devices must be different from the address of the ViscoPump. If, for
example 3 ViscoPumps are used in the AVS
and address 0 can then be used for other connected devices.
Please check the instructions for use of the respective devices.
