20 RS 232 Interface

Jack RS232 is provided for the connection of the following instruments:

• (P)SI module (accessory),

which can be inserted into the lid of the tester

•PC

• Barcode scanner of the following type:

B3261 with RS232 interface (article number: GTZ3261000R0001)

Z720A with RS232 interface (article number: Z720A)

or RFID scanner of the following type:

Z751G with RS232 interface (article number: Z751G)

20.1 Transmission of Measurement Results to the (P)SI module

Test results – except for results from individual measurements and the

function test – can be transmitted from the test instrument to the (P)SI

module, where they can be stored and printed out in the form of measur-

ing, test and statistics reports at any time.

20.2 PC Connection

Connection to an IBM compatible PC is also possible. The PC is

connected to the interface at the test instrument, or to the interface

port at a previously installed (P)SI module.

20.2.1Software Evaluation of Measurement Results

Convenient software programs such as PC.doc-WORD/EXCEL, PC.doc-

ACCESS or PS3 allow for easy preparation of measuring and test reports,

as well as archiving of measured data.

20.2.2Instrument Control via Interface Commands

All key functions included with the test instrument can be simulated

with the help of interface protocols, and the following parameters can be

queried:

• Type of measurement and measuring range

• Test setup

• Measurement sequence progress

• Detailed measuring results
