8 Data Interfaces
8.1 RS 232 Serial Interface
The data interface socket connector (4) is used to connect the
SECUTEST PSI module (feature I1), a barcode scanner (acces-
sory no. B3261) or the PROFI-MFII interface adapter (accessory
no. Z504H) for entering data with a PC keyboard.
Test results can be printed out at the SECUTEST PSI as a report
by listing measured values only.
An IBM compatible PC can also be connected to this interface,
thus allowing for data exchange.
Pins 9 and 6 may not be short jumpered to pin 5!
8.1.1 Software Analysis of Measurement Results
Test reports can be conveniently created at a PC and down-
loaded to the test instrument with the included software.
8.1.2 Interface Specification and Protocol
The interface included with the MERISO PRIME+ complies with
the RS 232 standard.
Technical Data:
Baud rate 9600 baud, fixed
Character length 8 bit
Parity none
Stop bits 1
All MERISO PRIME+ control functions can also be remote con-
trolled via this interface. Signal and display values can be read out
as well.
A description of the interface protocol, as well as commands and
syntax, can be requested from GMC-I Messtechnik GmbH.
