4.2 External Connector
The External Connector makes all of the MTi-600 pins available on a 2.54 mm pitch header. The pin
numbering is an exact copy of the MTi-600 pinning itself. All pins have a direct connection to the MTi-
600 except for pin 1 (Vext). Pin 1 is connected though a diode and can only be used to power the MTi-
600 (not for monitoring). The pinning can be seen in Table 4.

4.3 Power
The MTi-600-DK can be supplied by USB or through the External Connector. In case the External
Connector is used to power the board, the USB power will be disconnected from the MTi-600.
Additionally, pin 9 of both DSUB9 connectors can be connected directly to pin 1 (Vext) of the External
connector by placing the corresponding zero-Ohm resistor.
The DSUB9 VIN_Ext pins are directly connected to pin 1 of the External connector
when the zero-Ohms resistors are placed. Do not supply power to more than one of
these pins at the same time!
