CD1.1 Tools for Platinum
The Authentication card slot field is used when subframes
are signed. The Spyrus card used for signing can store
nineteen different key-pairs and this parameter selects which is
to be used. If signing is not required, this can be left set to
“disabled”.
The next section of the configuration screen controls channel
selection and channel name mapping. There is a channel
name mapping mode selection drop-down menu and a table of
channel names and associated parameters.
The channel name mapping mode selection drop-down menu
allows you to choose between three channel name mapping
modes:
•
In automatic naming mode, the system will
automatically generate names for the output channels
based on the incoming channel name and any
associated meta-data. If the incoming channels have
usable names, they will not be changed.
•
In semi-automatic mode, the mapping in the channel
name table will be used. Any channel not named in
the table will be mapped with an automatic name (as
in automatic mode).
•
In manual mode, only the channels in the channel
name table will be used.
CD1.1 channels are named either STATION.CHANNEL or
STATION.CHANNEL.LOCATION where STATION consists of
between 1 and 5 characters, CHANNEL of between 1 and 3, and
LOCATION (if present) of between 1 and 2. Valid characters are
A-Z (upper-case only) and 0-9. The period character in the
name serves to separate the components of the name.
If desired, the instrument type and calibration for the channel
description fields may be entered into fields in the table. If left
empty ("auto" for instrument type), then gdi2cd11 attempts to
determine these values automatically.
The columns in the table are:
•
System name — This is the name as used in gdi-
base.
