4.5.3 PC/external printer (RS232 interface)
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 devices.
The data output automatically switches to the RS232 interface.

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.
