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
