Taking the Product Back and Recycling
Applicable to product that is sold into the European Union, the European Union has passed a directive called
Waste Electrical and Electronic Equipment, or WEEE for short, to ensure that systems are setup throughout the
EU for the collection, treating and recycling of electronic waste.
This ensures that the devices are recycled in a resource-saving way representing no danger to health or the
environment. The WEEE symbol is shown at the right.
The WEEE symbol on the product or its packaging shows that the product must not be disposed of as residual garbage. The
user is obliged to collect the old devices separately and return them to the WEEE take-back system for recycling.
The WEEE directive concerns this device but not external cables or batteries. For more information on this recycling
program, contact your local service center.

Universal Serial Bus (USB)
The MDI has a xed USB conguration which cannot be changed. This ensures that the MDI can always be connected to
a single PC running the MDI Manager software so you can congure to LAN or WLAN congurations required by your local
network. Refer to the MDI Network Communications Setup Functions or the PC application help le supplied with MDI
Manager software.
The connectors on the USB cable are slip in connectors that do not have any kind of a latch. In order to keep the USB cable
connected, you can secure it to the MDI using the supplied cable keeper (Figure VIIC-4a). The cable keeper is secured to
the MDI case with a screw, the USB cable is inserted into the slot, and then plugged in as shown in Figure VIIC-4b.
Local Area Network (LAN)
The MDI’s LAN connection is setup and congured while the MDI is
connected over USB to a PC running the MDI Manager software. After
conguring, the MDI is connected to the LAN using the ethernet cable.
Refer cable to MDI Network Communications Setup Functions or the
PC application help le supplied with MDI Manager software for details.
The connectors on both ends of the Ethernet cable are latched. To
disconnect them you must press down on the latch (Figure VIIC-4c)
while you pull the connector out.

Data Link Connector and Cable
Communication between the MDI and the vehicle’s electronic systems is through the heavy duty 16-pin to 26-pin Data Link
Connector (DLC) cable that is connected to the bottom center of the MDI.
Power Source
The MDI is intended to be powered from the vehicle battery via the DLC Cable.
The MDI may also be powered using the AC 12-volt adapter with a UAL approved extension cord or when located near a
suitable wall socket.Typically the AC 12-volt adapter is used during bench operations or when conguring the MDI, updating
software, or during testing of MDI.
To comply with safety regulations, use only an approved AC Adaptor. One has been shipped with your MDI. Phihong
Model PSA15R-120P is approved for all MDIs. For MDI with manufacturer part number F-00K-108-062, Regal JG-
12151-N is also approved.
