1.1.4 General operating and safety strategy of Technica
Engineering’s Products
Technica Engineering’s products are designed for operation in automotive systems
and for supply voltages of nominal 12 V or 24 V. The applicable limit values adhere to
the standard norms for 12 V or 24 V automotive onboard power systems
correspondingly and can be found in the mentioned norms.
Should Technica Engineering’s products be operated in voltage ranges beyond those
specified in the norms, which represents a breach of the conditions of operation, then
this will void the product warranty and Technica Engineering will assume no liability
whatsoever of the results and/or consequences thereof.
This is especially valid whenever the voltage level reaches or exceeds the limits of the
low-voltage directive. In this case, damage to the devices cannot be excluded. Due to
the manufacturing characteristics of the devices, there is no imminent fire hazard from
the device itself, if the devices are being operated in an environment according to the
conditions of use. A secondary fire hazard cannot be excluded, should those
conditions not be met. A protection against overvoltage cannot be provided in such a
breach of the conditions of use.
1.1.5 General design rules for the power supply of Technica
Engineering’s products
The power supply circuit of Technica Engineering’s products are equipped with self-
protection components. This automatic function protects the devices against
excessive temperature and too high supply-voltage by switching the device off. This
automatic switch-off function is independent of any software function.
The root-cause of excessive temperature in the power supply circuit can eventually be
due to a too high environment temperature or due to an internal failure of the device.
In both cases, the automatic switch-off function will switch-off the power supply from
the device to avoid further damage.
The protection against too high supply-voltage protects the device even in case of an
internal failure of the Technica Engineering device.

The power supply for the device is supplied by Pin 1 (12Volt) and Pin 2 (Ground).
Requirements for the MediaGateway itself: 12 Volts DC up to 1 Ampere (typical
600mA)
Please note, that the power supply for the 12 Volts camera power output is also
supplied form Pins 1 and 2.
Warning: If you apply a voltage higher than 16 Volts, the device will be damaged!
A wake-up line can be connected on Pins 7 or 8. The wake-up line should have the
same voltage level as the power supply (12 Volts). A high level on one of these pins
wakes up the ECU from sleep mode and keeps it active. If the voltage on this pin drops
below approx. 6 Volts for more than about 3 seconds, the ECU will enter sleep mode
until voltage increases and it wakes again.
The LIN interface on Pin 9 can be used to communicate with the microcontroller by
LIN bus. In the default software there is no data transmission specified. This interface
may only be used in customer specific software.
The FlexRay interface on Pins 17 and 18 can be used to communicate with the
microcontroller by the FlexRay bus. In the default software there is no data
transmission specified. This interface may only be used in customer specific software.

You have to connect the (P) pin to the (P) pin of the periphery device. You have to
connect the (N) pin to the (N) pin of the periphery device.
Note: If you swap these two pins, the link LED may be lit on the 100BASE-T1 slave side,
but no data transmission will be possible.
The pins marked with (+) or (-) are 12 Volts power output pins. The actual voltage level
of these pins depends on the supply voltage of the ECU. Be aware that the sum of all
12 power output pairs will deliver a maximum of 1.2 ampere. If more current is used
the output will temporarily switch off.
The power output has to be switched on by website configuration (Control panel).
2.1.3 RJ-45 Ethernet connectors
There are three RJ-45 Standard Ethernet Connectors at the front side for Gigabit
Ethernet. They are working with autonegotiation for 10/100/1000 Mbps.
2.1.4 SFP Slot
There is one SFP cage for a MiniGBIC module.
The following modules have been tested:
Edimax Mini GBIC (SFP) LC, 1 Gigabit/s, 1000 Base-SX Module
SFPEX S1GT-A Mini GBIC (SFP) 10/100/100 Mbps RJ-45 Module
BEL SFP-1GBT-05 SFP 10/100/100 Mpbs RJ-45 Module
Note: Technica Engineering´s 100/1000BASE-T1 SFP Modules are compatible with the
MediaGateway!

2.2 Other Interfaces
2.2.1 Status LEDs
The MediaGateway has several status LEDs at the front side of the case.
Figure 2-2: LEDs
The “Host” LED can toggle at three different speeds:
Slow toggle (approx. 0.5 sec) during normal operation to show that the
microcontroller is running in normal mode.
Fast toggle (approx. 0.1 sec) when the microcontroller is in bootloader mode.
The bootloader mode is used for firmware update only (see below in this
manual). You cannot access the website when the device is in bootloader
mode.
When the device is in bootloader-update mode the LED toggles with moderate
frequency (ap- prox. 0.25 sec).
Note: If the HOST LED is stuck, the microcontroller is overstrained. Please make sure
that only necessary communication hits the microcontroller port (S1-P4) and try a
power reset.
The 12 port status LEDs of all 100BASE-T1 Ports monitors the link status of the
corresponding port. The LEDs are lit when there is a BroadR-Reach link detected. They
begin to blink when there is data traffic on this link.
Note: There is a known issue: Whenever P/N of the bus swap, data transmission won’t
be possible, not even if the LED is lit in the 100BASE-T1 slave side.
The In-built LEDs in RJ-45 connector shows the status of the gigabit ports. The left
(orange LED) is lit by a link-up. The right (yellow) will blink on data traffic.
2.2.2 Push Button (Reset to default)
The push button on the very left side at the front side of the case (hole) will reset all
settings to factory default.

MediaGateway User Manual
18
Press this button down for 5 to 6 seconds with a pointy stick or pen while the HOST
LED is blinking normally.
After that:
IP Address are set to default (192.168.0.49)
Complete configurations are lost and set to default
Note: If the device is blocked and all LEDs are lit, device must be sent to Technica
Engineering. In order to avoid controversies here please make sure that the HOST LED
is blinking its normal operation mode and the power supply is stable before the reset.

3CONFIGURATION OF DEVICE
3.1 Access to Webserver
You get access to the Webserver by connecting the device via a GB-port (RJ-45) to
your PC.
1. Please go to the network adapter settings of your PC and adjust the IP in the
same range of your MediaGateway. Default-IP address of the MediaGateway is
192.168.0.49, the subnet mask is 255.255.255.0.
2. Enter the IP address of the MediaGateway in your browser.
Note: Firefox is the recommended browser.
3. The following website should appear:
Figure 3-1: Home Screen MediaGateway
Note: If there is a lot of broadcast traffic on the switch, the host microcontroller
may be jammed. You cannot access the website in this case. Please use VLAN
configuration to forward only relevant messages to the microcontroller.
Sometimes a power reset works, too.
Please select one of the tabs for further configuration.

3.2 Save changes
If you changed anything in the configuration the following hint appears every time:
Figure 3-2: Save Configuration
You don’t have to save every time when this hint appears. You can make all wished
changes and save the configuration at the end. Please check the box “restart after
saving” and then press the “Save configuration” button.
After the restart, all changes are applied.
3.3 System Information tab
Figure 3-3: System Information tab
On the tab “System Information “, some status information about the device is
displayed. You can check the version number of the application firmware and the
bootloader or the unique MAC address of the device. The version number registers of
the switch and PHY chips are displayed for information only.
