3.12 Connection of devices via RS232 interfaces
The 746 VA Trace Analyzer has two interfaces 16 16 and 17 17 of type RS232C, which
are identical in hardware terms but differ with regard to software (in the functioning
of the 746 VA Trace Analyzer) (see Fig. 24):
RS232 interface 1 • Attachment of a PC
(”remote keyboard” function possible) or
• Attachment of a printer
RS232 interface 2 • Attachment of a PC
(”remote keyboard” function not possible) or
• Attachment of a printer and/or
• Attachment of a balance (balance and printer
can both be attached at the same time)
The technical data of the RS232 interfaces can be found in section 8.3. The present
section describes the procedure for the attachment of devices to the RS232 inter-
faces. To configure these interfaces, dialog page ”VA TRACE ANALYZER” must be
selected (see section 5.3.1).
Before connecting a device to the RS interfaces, the 746 VA Trace
Analyzer must be switched off by means of mains switch 11 11. The
attachment of devices to the 746 VA Trace Analyzer when it is
switched on can necessitate initialization of the RS232 interfaces (see
section 5.3.1)!
