4 Adapter Connection and Initial Start-Up
4.1 Connecting the Adapter
The screw connections between the stacked adapters serve exclusively to secure the
connections at the serial interface plug connectors. Disconnect each individual adapter prior
to transport in order to prevent them from being damaged.
➭ Connect the 9-pin subminiature socket at the connector cable to a vacant COM port at
the PC.
➭ Plug the other end of the cable into the left side of the first adapter. Plug additional
memory adapters into the right side.
➭ Secure the plug connections between the individual memory adapters by tightening the
screws.
➭ Plug the multimeters into the adapters.
Caution
The memory adapter’s housing is made from electrically conductive plastic. It may
not be allowed to come into contact with voltage conducting components.
4.2 Initial Start-Up - SI232-II Memory Adapter
Before data can be transmitted to the PC, an individual address must be selected for each
memory adapter, and the memory adapter must be set to transmission mode operation (PC
or online) (see memory adapter operating instructions).
If several memory adapters are used, the same transmission speed must be selected for all
devices.
If more than 4 memory adapters are used in the online mode, a transmission speed of 19,200
baud must be selected in order to assure interference-free data transfer.
➭ Set the required multimeters to data transmission before performing measurement by
simultaneously pressing the DATA key and the ON key.
➭ Check the addresses for the interconnected memory adapters.
➭ Start the PC and METRAwin 10 software.
All interconnected memory adapters are addressed via the serial port and a connection
with the PC is established automatically (see PC function, chapter 6.2, page 12 and
chapter 7.10, page 22).
➭ Activate “Adapter” under menu item “Set/Channels” in the “Interface” field and select the
appropriate port and transmission speed for your system.
➭ Check data transmission to the PC by clicking the “Test” button under menu item “Set/
Channels”.
➭ The memory adapters can be addressed and configured individually under menu item
“Set/Memory adapter”, and the clock and transmission speed can be selected.
➭ In order to perform a measurement, click “Operating mode: ONLINE” under menu item
“Set/Memory adapter”. All memory adapters connected to the interface are placed
online and can be queried with their respective addresses.
➭ Save the selected configuration under menu item “Set/Save configuration”.
This command saves all configurations which have been selected in the “Set” menu.
Measurements can then be performed with the selected configuration.
