3 Pinning
The pinning of the ECU connectors is listed on the label on top of the device.
The Tyco Electronics (TE) Micro Quad Lock System (MQS) is used.
Tyco, MQS Abdeckkappe, 2x9 Pol, black Part Number 1-967416-1
alternatively Part Number 1-1355350-1
Tyco, MQS Abdeckkappe, 2x9 Pol, blue Part Number 3-967416-1
Tyco, MQS Buchsengehäuse, 2x9 Pol Part Number 965778-1
alternatively Part Number 962108-2
Tyco crimp contact Part Number 928999-1
Note: You can use the official Tyco tool for these crimp contacts. A cheap variant is the
crimp tool for “PSK” contacts.
3.1 Power connector (top left)
Connector color: Black
Power supply for the device is supplied by Pin 1 (12Volt) and Pin 2 (Ground).
Requirements for the MediaGateway itself: 12 Volt DC up to 1 Ampere (typical 600mA)
If the 12 Volt camera power output is used, this current is also sourced of Pin 1 and 2.
Warning: If you apply a voltage higher than 16 Volt, the device will be damaged!

CAN Bus interface (CAN A) on pins 5 (BP) and 6 (BM). This interface may be used for CAN
based wakeup and data transfer. In the default software there is no data transmission speci-
fied. This interface may only be used in customer specific (Gateway) software.
CAN B to CAN E do not support wakeup functionality. They are for data transfer only.
A wakeup-line may be connected on pin 7or 8. The wakeup-line should have the same volt-
age level as the power supply (12 Volt). 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 Volt for
more than about 3 seconds the ECU will enter sleep mode. It will wake up on a high level
again.
Alternatively the “Prevent sleep“ checkbox in the control panel of the website can be ena-
bled.
Attention: Ethernet Traffic on any port will prevent sleep mode. Timeout is set to 100 sec-
onds.
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 pin 17 and 18 can be used to communicate with the Microcontroller
by FlexRay bus. In the default software there is no data transmission specified. This interface
may only be used in customer specific software.

3.2 Switch connectors
Connector color: blue
The pins marked with (P) or (N) are used for the BroadR-Reach ports. Four ports are availa-
ble per switch.
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 BroadR-Reach slave side,
but no data transmission will be possible.
The pins marked with (+) or (-) are 12 Volt 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
temporary switch off.
The power output has to be switched on by website configuration (Control panel).

3.3 RJ45 Ethernet connectors
There are three RJ45 Standard Ethernet connectors of the front side.
3.4 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 MBit RJ45 Module
BEL SFP-1GBT-05 SFP 10/100/100 MBit RJ45 Module

4 Status LEDs and Pushbutton
The MediaGateway has several status LEDs at the front side of the case.
The “Host” LED is toggles slowly (approx. 0.5 sec) during normal operation to show that the
microcontroller is running in normal mode. It is toggling fast (approx. 0.1 sec) when the mi-
crocontroller 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
(approx. 0.25 sec).
The port status LEDs Switch 1 to 3 and Port 3 to 0 monitor the link status of the correspondig
port. The LEDs are lit when there is BroadR-Reach link detected. They begin to blink when
there is data traffic on this link.
Note: There is an issue when P/N of the bus are swapped. The LED may be on in this case
on BroadR-Reach slave side, but there will be no data transmission possible.
The LEDs built in the RJ45 connector show the status of the gigabit ports. The left (orange
LED) is lit by a link-up. The right (yellow) will blink on data traffic.
The pushbutton on the left side of the case will reset all settings to factory default.
Press this button down for 10 seconds with a pen during powerup/startup of the device.
The IP Address will be reset to default (192.168.0.49)
All settings will be lost.
Note: The MAC Address will not be changed.

5 Configuration Website
You can access the configuration website with a standard web browser (Firefox is recom-
mended, Chrome is not recommended).
Connect your PC to a RJ45 connector.
The default IP address of the device is 192.168.0.49 and subnet mask 255.255.255.0
If someone has changed the IP address you can reset it to default as described in chapter 3
of this manual.
For example set the configuration PC to IP address 192.168.0.100 and subnet mask to
255.255.255.0

5.1 Website Home
Warning: If there is a lot of broadcast traffic on the switch, the host microcontroller may be
jammed. You can not access the website in this case. Please use VLAN configuration to
forward only relevant messages to the host.
With the first access to the website you will get the home screen. Please select one of the
tabs for further configuration.
5.2 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
