Operation and configuration
14 TGH1365en/10.2012
4.1.1 Connecting a printer
A printer can be connected to print out the test results. Providing that:

The printer used has an IBM 8-bit character set

The printer is set to IBM emulation
GDI printers (GDI = Graphic Device Interface) are not suitable for the UNIMET
®
300ST.
You need a standard printer cable (25-pole D-Sub plug to Centronics) to connect the printer. This ca-
ble is not included with the equipment.
4.1.2 Connecting the keyboard and barcode scanner
A keyboard and/or barcode reading wand or barcode scanner can be used to make it easier to input
the ID numbers and names of test engineers. UNIMET® 300ST supports the PS/2 interface to which
either a standard keybboard, a PS/2 barcode-pen reader or PS/2 barcode scanner can be connected.
If an AR100 barcode-pen reader is connected to a PS/2 keyboard switch cable (see “Ordering data”
auf Seite 57.), it can be connected to a keyboard at the same time. If no keyboard is connected, then
plug the keyboard simulator supplied with the AR100 barcode-pen reader to this port.
The keyboard and barcode pen reader or barcode scanner can be plugged in and unplugged during
operation. Adjustments on the UNIMET are not necessary. The keyboard and barcode pen reader
must not be connected before switching on the UNIMET. This increases flexibility during testing.
When the UNIMET detects a PS/2 keyboard, then the "Num-Lock" LED lights up. The LED indicates
that the keyboard is ready.
4.2 Principle of operation
4.2.1 Operating the device
All the functions of the UNIMET
®
300ST are controlled using the four control keys and the displays on
the screen. The current position on the menus is indicated by a flashing marker (cursor).
Earthed printers can affect the measurements. Therefore, during the measure-
ments, make sure that either
- the Centronics interface is not connected to an earthed printer or
- the Centronics interface is electrically isolated via a suitable component.
 
Use the arrow buttons to move the cursor up or down on the menus.
Use the Enter button to confirm selection of the current menu item.
