3 Pinning
The pinning of the ECU connectors is listed on the label on top of the device.
Connector color: Black
Power supply for the device is supplied by Pin 1 (12 Volt) and Pin 10 (Ground).
Warning: If you apply a voltage higher than 18 Volt, the device will be damaged!
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 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.
Warning: The Power “loop through” function is just a short circuit between pins 1-2
and pins 10-11. There is no fuse and no diode. If the current exceeds 0.8 Ampere the
device will be damaged!

4 Configuration
The MediaConverter is configured by 2 DIP Switches on the front of the device.
DIP Switch 1: ON = BroadR-Reach Port is set to Master.
OFF = Slave
DIP Switch 2: ON = BroadR-Reach Port is set to FullOut.
OFF = HalfOut
Note: In a BroadR-Reach Link one device has to be set to Master, the other has to
be set to Slave Mode.
Note: The MediaConverter should always be set to FullOut. HalfOut was a former
configuration for EMC optimization but will cause an instable link.
