5 AC 800F Functional Description

5.4 Diagnosing the AC 800F
The diagnostic interface RS232 on the power supply module serves for diagnosing. It
is solely used in case of error, in the Boot Loader configuration dialog or for
connecting the radio clock DCF77 or a GPS clock.
A standard ANSI terminal (e. g. DEC VT 100, Visa MC4, Ampex A230 or similar) or a
PC or laptop with a free serial interface is used for diagnosing.
The description in this section assumes that the engineering station is used as a
diagnostic PC. The scope of delivery of MS-Windows NT 4.0 and MS-Windows 2000
includes a terminal emulation which you can use for diagnosis. The settings for all
other terminal emulations or terminals are identical or similar to those described
below.
Link the AC 800F with the diagnostic PC as described in Section 4.1.5, using cable
TK 890F or TK 891F. Use the 9-pin port of the PC. For terminals with 25-pin
connector additionally use a commercial adapter.
The diagnostic PC can be connected to a running AC 800F when live.
When connecting the diagnostic PC to a running AC 800F, first start the
terminal emulation and configure as specified. Connecting a PC on
which the terminal emulation is not yet running may stop the AC 800F,
since the hardware handshake lines can only be operated correctly after
the terminal emulation has been started.
The AC 800F with power supply SA 801F/SA 811F has a protective
separation from other circuits. Connecting a diagnostic PC which has
no protective separation and is not battery-powered may cancel out
this separation.
