11.5 Analog / Digital Input
The blue PiraT Mini has three analog and three digital inputs, whereas respectively the first
channel is located in the logger and records the input voltage. The measuring range is between
0 V and + 20 V, the accuracy is 3 %. The sampling rate is adjustable from 1 ms to 100 s. The
switching threshold for the digital input is 7 V ± 0.2 V, see chapter 14 Data sheet.
The interfaces are combined, which means that either ANA or DIG is usable.
The combined ground has to be connected always!
11.6 Digital Output
The blue PiraT Mini models CAN, FlexRay and LIN have two digital outputs. The output current
is up to 2 A.
11.7 Ethernet
All versions of the blue PiraT Mini data logger are able to log Ethernet data. All data loggers
have two 1 Gbit Ethernet ports with RJ45 connector on the front and two more at the rear side.
The two interfaces
ETH #1 / TSL
and
ETH #2 / TSL
can be used to connect the data logger to
the PC and for the TSL (Telemotive System Link) connection.
At blue PiraT Mini CAN the two interfaces ETH #3 and ETH #4 can be configured and
used either as IEEE 802.1 Ethernet or as Broad-R-Reach

11.7.1
Supported protocols
This section gives an overview of the available protocols. When a protocol requires a license,
this will be marked.
11.7.1.1
GNLogger
For connecting a standard TCP (open socket connection) is used. Therefore the blue PiraT Mini
is a TCP slave device.
GNLogger is a proprietary serial protocol used for some ECU diagnosis.
11.7.1.2
UTF8
The blue PiraT Mini will initiate a TCP connection to a TCP server by using an open socket con-
nection (you can configure IP/Port of server via client software).
By using UTF8 data transmission the logger will write a timestamp after every detected Linefeed
(LF) from the incoming data.
If the connection is getting lost, it will take about 5 seconds to build up a new connection for
logging data again.
