Tutorial Install Usb Port

The main dashboard module has a free 6Pin Connector.

The Pinout of the connector (MQS generation II) is as follows:

USB CONNECTOR

. . . . . . . . . 6 | o o | 3
. . . . . . . . . 5 | o o | 2
. . . . . . . . . 4 | o o | 1

Pinout (according to PSA documentation) :

1 Reserved
2 Reserved
3 +5V (red cable)
4 GND (black cable)
5 USB Data (white cable)
6 USB Data + (green cable)

Note: the colors of the cables are the standar used in USB cables, but they could be diferent.

This kind of connector is widely used by PSA for a lot of purpose (warning, auto AC, …). But for some usages,
only 3 pins are present on the connector. In this case, you have to buy 2 of them to have one usable for the
USB.

Instructions:
Just connect an usb flash drive according to the pinout!

** DO NOT REVERSE THE +5V AND GND OR ELSE YOU COULD DAMAGE YOUR USB FLASH DRIVE OR
EVEN THE RT4 SYSTEM. **

(reversing the data pins caused no problems in my RT4, but be advised that you are at your own risk!.)

It is recommended to use an USB flash drive with a read/write access led, so you can visually check that the
system is reading or writing data from the flash disk.
