2 Hardware Description
2.1 General
This embedded controller has been designed for industrial environments and offers a high degree of
flexibility, performance, and reliability.
All components are cooled passively.
Factors like quality, availability, and high durability are of particular importance for the selection of our
components.
Exhaustive tests of the embedded controller are performed by our company. Each device undergoes an
in-depth function test. This function test includes a burn-in test with full communication on all interfaces
(min. 48 hours). Communication disruptions, transmission errors, and every important component with
regard to function, temperature, voltages etc. are monitored. Hundreds of restarts are executed whereby
connections to all interfaces are re-established at each reboot.
Quality assurance is conducted according to the four-eye principle. Each device passes a number of
quality inspections.
The mounting brackets can show slight signs of usage.

2.3 Ethernet Line Breaker E1-E4
The industrial breaker for Ethernet lines consists of three functional areas:
The status indicators –E1-E4
The mechanical control switches –E1-E4
Ethernet relay ports arranged in pairs –E1-E4
Figure 3: Ethernet relays E1 –E4
A 3-way switch is provided for each Ethernet interface pair E1-E4 to manually control their
communication state.
ON –Manually switched on
REMOTE –Control via Software
OFF –Manually switched off
In the switch position REMOTE, software control is possible via a communication protocol or via a
graphic web interface (WebConfig - diagnostic area).
Bistable relays are used as "ON/OFF switches" for each of the eight individual lines of an Ethernet
connection. . These remain in their current state even after a power failure or other interruptions. The
partner interfaces are connected or disconnected to each other with the same pin configuration (1:1).
For the RJ45 interface description see chapter 2.4.4 Ethernet-Relays E1-E4.
For the Diagnostic LED’s see chapter 3.2 Status LEDs E1-E4.

2.4.4 Ethernet-Relays E1 –E4
The embedded controller offers four RJ45 relay interface pairs.
RJ45 female –RJ45 female
The interface pairs are wired through or separated with the
same pin layout (1:1).
Compatible for 10M/ 100M/ 1G/ 10G Ethernet connections.
Figure 6: Pin assignment Ethernet relay interface pair
2.4.5 I/O Interfaces
The embedded controller features eight digital inputs and eight digital outputs.
The digital inputs are equipped with overvoltage protection.

The digital outputs are also equipped with overvoltage protection and an additional overcurrent
protection. In case of a fault, the respective digital output switches to a high-impedance state. This
safety-shutdown of a digital output can be reset by setting the specific output to “low” (pin 10 - GND)
via the software.

2.4.6 Flash (Mass Storage)
An SLC NAND flash is used for mass storage, on which the operating system, the gateway software,
and all configuration data is stored. The major advantage over a hard disk drive is the elimination of
moving parts, which significantly increases the reliability.
2.4.7 Lithium Battery
When the system is powered off its real-time clock is buffered by a battery. The durable lithium battery
generally offers a lifespan of more than 5 years.
The default settings are designed in a way that the gateway can operate without errors even after a
battery failure. After replacing the battery, the date and time must be re-synchronized (NTP). When the
gateway is time synchronized, the current time and date information is available to the system without
a battery as well.
Only a qualified electronics technician should perform the battery replacement. However, there is the
possibility to instruct IPCOMM GmbH with this task. Incorrect replacement might yield the danger of
explosion. Replace the battery exclusively with the same type (3 V DC, CR2032). Used batteries are to
be disposed in accordance with the manufacturer's instructions.
Contact IPCOMM GmbH to order a low priced spare battery.

CAUTION: The device must be de-energized. The change of a battery requires ESD safety
measures to avoid charge transfer to the circuit board and system components.
Please perform the exchange only on an earthed and conductive surface when
using an antistatic wrist strap!
Battery replacement:
1. Disconnect the embedded controller from mains; disconnect data lines.
2. Dismatle the device from the 19” rack.
3. Unscrew and lift the housing cover by loosening the corresponding nine screws. It is
recommended to use a Torx screwdriver of size T10.
4. Pull the old battery out of the battery holder.
5. When inserting the new battery, make sure the polarity is correct (see polarity marking on the
battery socket).
6. The embedded controller can be put back into operation after the correct installation.
Figure 9: Battery
Caution: When replacing the battery, pay attention to the polarity of the battery!
2.4.8 Power Supply
The SEC3ER must be connected to a voltage of 230 V AC or 115 V AC via a standard IEC cable. For
further information, see chapter 4 Technical data sheet.
CAUTION: Before opening the device, it is mandatory to switch the device voltage-free!

If the PWR LED is lit, the module is supplied with voltage.
The USR LED is freely configurable. An imaginable function would be to display a particular connection
status (or more than one as an overall status).
3.1 CPU-LED
The CPU LED visualizes the status of the operating system and the gateway software.

3.2 Status LEDs E1 –E4
Figure 12: LEDs E1 –E4
The status LEDs of the interfaces E1 –E4 visualize the current status as follows:
If the red LED (ON) is lit, communication is possible on the corresponding Ethernet interface.
(relay closed)
If the green LED (OFF) is lit, communication is not possible on the corresponding Ethernet
interface. (relay open)
If the orange LED (REMOTE) is lit, the software determines whether communication via the
corresponding Ethernet interface is possible. The status LED for ON or OFF lights up
accordingly.
If no ON or OFF status LED lights up for a connection, for example "E2", the connection is not ready
(possibly nothing connected).

Figure 13: LEDs for digital inputs
When the input level "high" is reached, the input diagnostic LEDs DI 1 to DI 8 light up green.
3.3.2 Digital Outputs
Figure 14: LEDs for digital outputs
If a digital output is activated (UVSO switched to output), this is indicated by the green output diagnostic
LED DO 1 to DO 8. In case of a fault, the respective digital output changes to a high-impedance state
and the LED turns red.
