The QC250 SAFEmine devices include a self-contained WLAN module. The module is a complete
IEE 802.11 b/g/n based wireless device.
The module supports WPA2-PSK, WEP (64 and 128 bit) and TKIP security encryption.
The typical transmit power is 17dBm for 801.11b, 15dBm for 802.11g/n. The sensitivity is -97dBm @
1Mbps to -71dBm @65 MBps.
The connector is a reverse polarity female SMA (RP-SMA) with center pin contact and outside
threads for passive WiFi Antennas with 50 Ω wave impedance.
Only antennas supplied by SAFEmine may be used.
3.5.6. Main Interface
The main interface has a 8-pin M12 male connector. This interface is connected to the vehicle and
optional add-on modules. It provides the connection points for power supply and communication
ports a dedicated voice signal line as well as one configurable digital I/O:

Please consult chapter 4.6 for general instructions on configuration of I/O’s.
Use of CAN-Bus, Serial Port, I/O1 and Audio connection depends on the application. They may be
left unconnected if not used.
The main interface also includes a hardwired input (I/O0) which is internally connected to pin 1 in
order to monitor the power supply voltage.
The SAFEmine CAS system can operate with a supply voltage down to 9V
dc
, but if the supply voltage
is below 9.6V at startup, an error code or a message indicating the low supply power is displayed
and the device will refuse service. If the supply voltage drops below 9.6V during operation, the
‘power’ LED will turn red and the error message is issued. In case the voice option is enabled ‘error
