power’ is announced every 30 seconds on the speaker as long as the supply voltage is sufficient to
do so.
3.5.7. Display / Serial Connector (only QC230 & QC235)
The QC230/35 MainUnit has a female 4-pin M8 display connector and is placed next to the main
connector interface. On the QC24X/220/250 devices the display connector has been integrated into
the main connector and is branched out through the QM106 serial Y-cable.
This connector provides the data and power necessary for the display. The display connector can
also be used for debugging and firmware update purposes. The protocol used on the display serial
connector is standard RS232

The serial communication port is used for the display communication as well as for configuration, programming and
debugging.
3.5.8. I/O Connector (only QC220/240/250)
The I/O connector is an 8-pin M12 male type. The general purpose input output (GPIO) ports present
on the I/O interface of the device can be used to monitor and record vehicle parameters such as:
reverse gear, seatbelt clicked, bucket position, bucket load, fuel gauge, etc. The vehicle signals can
be used to influence the behavior of the CAS system in order to react to different situations.
Additionally, the traffic and GPS information gathered by the CAS MainUnit can be used to trigger
outputs in order to control external applications.
The GPIOs are almost all on the I/O connector with the exception of ports I/O0 and I/O1. I/O0 is
hardwired to the pin 1 of the main connector in order to monitor the power supply voltage. I/O1 is
