12.2.2 Connecting the Configuration Computer
In order to download the configuration, a connection between the configuration
computer (PU or PC) and TP must be established. There are two connection
options available for this:
S the serial connection of a configuration computer to the TP interface IF2
(serial downloading),
S the connection of a configuration computer to the TP interface IF1B (MPI
downloading). In this case, the configuration computer and TP are con-
nected to the MPI network. A condition for this is that a configuration al-
ready exists on the TP.
Both connections serve for downloading the firmware and configuration data
(chapter 13.2). Standard cables are available for the connections shown (refer
to the ST80.1 catalog).
