2.2 Connectors and Operators
The 24 pin multi connector provides access to many of the Gateway ZAbluegalaxy / DIG-2019NE
interfaces that are described later.
A suitable mating connector with lock-and-release levers is Phoenix Contact order number 1790580. A
model witch screw locking is available with order number 1790399.
The plug uses spring-cage connection and accepts solid or flexible wires from 0.2 mm² to 1.5 mm². Push
in connection is possible, in case of flexible wires you have to use ferrules for this. If you use ferrules
with plastic sleeve, the maximum wire size reduces to 0.75 mm².
Stripping length for the wires is 10 mm.
If you use ferrules, obey that standard ferrules for 0.75 mm² have only 7 mm length.

DANGER
The product may only be operated with power supplies which can be considered SELV
circuits.
Pins 21 and 22 should be connected to EMI protective earth (PE). These contacts are internally
connected to the DC power supply EMI filter and to the D-SUB shell of the console (RS-232). The signal
is doubled to prevent false connection, it only requires one connection. In locations where no EMI noise
is present, the PE connection is not required. The PE has no safety function.

Table 2: Serial Port connector pins
In the RS485 mode the bidirectional differential signals D+ and D- are provided. When the transmitter
is enabled and no data is sent (1=MARK), then D+ > D- (refer to figure 5).
Note that D+ corresponds to pin “A” of the transceiver chip. However, this is signal B according to the
EIA-485 or Profibus standards.
The receiver has the fail-safe input feature, which ensures that no data is received when D+ and D- are
floating or are shorted (e.g. by the termination resistor).
For each serial port, an internal 120 Ohm termination resistor can be enabled between D+ and D- by
shorting jumper J300 or J400. The case must be opened to access these jumpers.
2.2.3 CAN (Gateway ZAbluegalaxy)
The CAN interface is implemented with a MCP2515 controller chip. The interfaces is located on the
multi connector, refer to table 3. The CAN interface signals support ISO 11898-2 (high speed) and are
isolated from system logic, as result it is always required to connect 13 GND-CAN and 17 GND1-CAN
to the belonging CAN ground.

NOTICE
If your Ethernet cable is long (normative limit = 30 m) or leaves a building, then an
additional protection against surges is required.
Add an external surge protector is such cases. E.g. ground the Ethernet cable shield
where it enters the building or your cabinet.
If you just connect to a nearby switch, such countermeasures are not required.
2.2.6 USB host interfaces (USB1-USB4)

Environmental Specifications
To specify an ambient operating temperature for reliable 24/7 industrial operation, the CPU and
GPU load are two very important factors. If all CPU cores are idle all the time, then the
maximum specified ambient temperature can be much higher than in a maximum CPU
utilization application.
The new BCM2837B0 system-on-chip has much more computation power than its
predecessors, but also gets far, far hotter. In high CPU load scenarios, the clock is dynamically
increased from 600 MHz to 1400 MHz and then produces so much heat, that even at room
temperature the clock would automatically throttle down to 600 MHz after several minutes to
prevent overheating.
Because of the thermal limitations of the used standard Raspberry Pi 3 Model B+ single board
computer, the form factor of the casing and the economic limitations in this entry level system,
no extensive passive cooling solution can be used. The internal baseboard designed by us
providing the power supply and the I/Os and two fieldbuses to the Raspberry Pi board, would
allow an ambient operating temperature from -25…60°C but the Raspberry Pi board is the
limiting factor.
The embedded PC uses a passive heat sink on the BCM2837B0 chip and therefore is it not
possible to use all of the computation performance the BCM2837B0 provides. The system
power consumption ranges from 3.0 W (average when idle) to 9.5 W (maximum under stress).
To prevent CPU overheating and throttling, the maximum system power consumption should
not be higher than about 4 W. In most real world use cases of this embedded computer, the
average power consumption will be lower than this limit, but if constant CPU performance is
important for your application, then limiting the maximum CPU frequency to 600 MHz in
configuration file /boot/config.txt is one possibility to achieve this. Without limiting the maximum
CPU frequency, the CPU will dynamically change the frequency depending on the CPU
temperature (see commands: vcgencmd measure_temp and vcgencmd measure_clock arm).
Ambient operating
Temperature
0 .. +40 °C (vertical orientation / wall and DIN rail mounting)
0 .. +35 °C (horizontal orientation / desk-top mounting)
at sea level, derated by 1 °C per 300 m above sea level to
a maximum of 2000 m.
the above temperature ratings are defined under the following CPU
load:
•No GPU load
•4 cores loaded at 600 MHz or 1 core loaded at 1400 MHz,
where the load per core is comparable to that of the Linux
stress-ng utility
•The above numbers are without safety margins to
compensate process variations of the Broadcom SoC
•More load will bring the CPU Junction temperature above
80°C and the CPU will reduce clock frequency towards 600
MHz. The system will not overheat under such conditions.
