4.5.3 PC/external printer (RS 232 interface, pH 340i)

Via the RS 232 interface, you can transmit the data to a PC or an ex-
ternal printer.
Use the AK340/B (PC) or AK325/S (ext. printer) cable to connect the
interface to the instruments.
The data output automatically switches to the RS 232 interface.
Warning
The RS 232 interface is not galvanically isolated.
When connecting an earthed PC/printer, measurements cannot be per-
formed in earthed media as incorrect values would result.
Set up the following transmission data on the PC/printer:
Baud rate selectable between: 1200, 2400, 4800, 9600
Handshake RTS/CTS + Xon/Xoff
Parity none
Data bits 8
Stop bits 1

4.5.4 Remote control (pH 340i)

The measuring instrument can be remotely controlled from a PC. This
requires the KOM pilot communication kit. It is available as an acces-
sory.
The instrument is then controlled via commands that simulate key-
strokes and request the current display contents.
Note
A more detailed description is provided within the scope of delivery of
the communication kit.
