Note that the 60-pin connector of the AsteRx-m2a is not used by the interface card.
Refer to the board schematics in section 3.5 and to the picture on page 20 for the pinout
of each connector.
3.2
Power Supply Options
When an USB cable is connected, the interface board is powered from the computer
through the USB connector (J2).
Alternatively, the power can be applied from either:
•
Pin#1 of the COM1 connector (J3, or optionally with solder jumper J4 and J5)
•
An external 6-30V DC supply (J10).
Power can be applied from more than one source at the same time. On-board diodes
prevent short circuits (see schematics in section 3.5).
The interface card provides the 3V3 supply to the AsteRx-m2a receiver: there is no need
for a separate 3V3 supply for the receiver.
The interface card provides a 5V DC voltage to the VANT pin of the AsteRx-m2a.
The power consumption of the interface card is 150 mW (not counting the consumption
of the AsteRx-m2a).
3.3
LEDs
The PWR LED is lit if the interface card is powered and the supply voltage after the diode
selector is above 4V.
Refer to Appendix A for a description of the LOG and PVT LEDs.
3.4
Temperature Range
The interface board operates in the same temperature range as the AsteRx-m2a receiver
(-40 to 85°C).
3.5
Schematics
The interface board schematics is shown below. Components printed as dashed lines are
not fitted.
