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

100/1000BASE-T1 MediaConverter hMTDUser Manual
6
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.
1.2 Warranty and Safety Information
Before operating the device, read this manual thoroughly and retain
it for your reference.

2.1.4 Micro HDMI Debug Connector (4)
The micro HDMI debug connector is not to be used by the user. It is for development
only. The required debug cable and extension board are not part of delivery and cannot
be ordered.
This is not a video interface.
2.2 DIP Switches (5)
These DIP Switches are for configuration. You can find more information about
configuration in CHAPTER 3.1
2.3 Status LEDs (6)
The 100/1000BASE-T1 MediaConverter has 5 LEDs on the front side of the case.
LED
Description
Host LED
Will blink slowly (once a second), during normal operation of the device.
GP LED
General Purpose LED. Will be lit when the microcontroller detects an active
100/1000BASE-T1 link.
Error LED (red)
Will be lit when at least one CRC error is detected. This may happen when the
hMTD connector is plugged during operation.
Link LED
100 or 1000Base-T1 Link active.
Activity LED
100 or 1000Base-T1 Ethernet data transmission.
Table 2-5 LEDs Description
The 100/1000BASE-T1 MediaConverter has LEDs integrated in the RJ-45 connector.
For RJ45 connection:
Left side: Green = 100 BASE-TX link
Orange = 1000 BASE-T link
Right side: Orange = ACTIVITY
2.3.1 Resetting Error LED:
If the Error LED is lit red, a disconnection of the link can clear the LED. This can be
done by changing the DIP switch position to break the link and changing it back to form
a link again.

Normal operation
Table 3-1: Configuration of DIP Switches
For establishing a BASE-T1 link one device must be set as Master, the other must
be set as Slave.
It is not possible to mix two speeds of the ports. If the MediaConverter is
configured
for 100BASE-T1, the RJ-45 connector is always 100BASE-TX. If the
MediaConverter is configured for 1000BASE-T1 the RJ-45 connector is always
1000BASE-T.
3.2 Configuration through Power MQS Connector
The PINs 2, 3, and 4 of the Power MQS connector (CHAPTER 2.1.3) can be used for
configuration and link status output.

100/1000BASE-T1 MediaConverter hMTDUser Manual
13
3.2.1 Link Status Output (LS) (PIN 2)
The Link Status PIN 2 outputs a weak 3.3 Volts status signal. There is an integrated
5K Ohm pull up resistor to 3.3 Volts. This PIN is active high. The pull-down transistor
can drain up to 100mA.
3.2.2 Force Link Down (LD) (PIN 3)
If you connect PIN 3 and PIN 1 by a shortcut wire link down is forced. These pins are
active low. There is an integrated 5K Ohm Pullup to 3.3 Volts. For normal operation
please disconnect the PINs.
While removing the shortcut of PIN 3 and PIN 1, a full reset of the device will be
done.
3.2.3 Force Slave mode (FS) (PIN 4)
If you connect PIN 4 and PIN 1 by a shortcut wire Force Slave mode is activated.
These pins are active low. There is an integrated 5K Ohm Pullup to 3.3 Volts.
For normal operation please disconnect the PINs.
Activated Force Slave mode overrides the DIP switch configuration.
Force Slave mode must be applied before powering up. Otherwise, a power reset
is needed.
3.3 Frame Generator
The 100/1000BASE-T1 MediaConverter in frame generator mode is working only on
the BASE-T1 port as a frame generator. The generated frame is in total 1514 bytes
long and is sent with
Roundabout 12 Mbps in 100BASE-T1 mode
Roundabout 120 Mbps in 1000BASE-T1 mode

100/1000BASE-T1 MediaConverter hMTDUser Manual
14
The frame contains no specific MAC source or destination. All bytes have the same
pattern: 0xA5 and 0x5A in alternation.

4 STANDARD USE CASE
Here you can see a standard use case of the 100/1000BASE-T1 MediaConverter:
Figure 4-1: Example of a use case
MC
Media Converter
DUT
Device Under Test
DIP Switch 1: Master/Slave setting, is dependent on the DUT. If DUT is Master, MC
must be configured as Slave, DIP Switch 1 must be OFF [down], and vice versa
DIP Switch 2: 100/1000 speed setting is dependent on the speed of the DUT. If it
is a 100BASE-T1 connection DIP Switch 2 must be OFF [down] and vice versa
DIP Switch 3: Legacy/IEEE mode setting: If the PHY of the DUT is a Marvell PHY
A0 (Only 1000BASE-T1) then the DIP Switch 3 must be OFF [down]. If it is any
other IEEE 1000BASE-T1 conform PHY the DIP Switch must be ON [up]
DIP Switch 4: Frame Generator function, always must be OFF [down]. Only in
Frame Generator-Mode, the DIP Switch must be ON [up], in this case, the device
no longer works as a converter
