2.4.5 RS 232 port (V.24)
The RS 232 port can be used for connecting a laptop, PC or a printer to a
serial port. Programming of the PABX via PC or laptop is performed via this
port (see Programming). This port is not electrically isolated from the PABX
ground.
All work on the RS 232 port may only be performed when the functional
ground is properly activated. Devices which are to be connected via the
RS 232 port (e.g. PABX and printers) must first be switched off and discon-
nected from the 230 V AC power supply before connection is made.
