5 QPRO Data Interface Specifications
5.1 Data Interfaces
• 4 Digital Output Switches (2 Switched GND/2 Switched Input Power Voltage)
• 8 Digital General Purpose Inputs/Outputs (CMOS level 3.5VDC)
• 3 Serial Ports (External) Up to 4 RS-232 ports depending on QPRO configuration
• 1 CAN BUS 2.0: J1850/1939

Note: The auxiliary port is not available for customer use on QPRO models that include an Iridium or
Inmarsat satellite option
5.2 Environmental Considerations
The QPRO has been specifically designed for harsh environments. As an OEM product, it is housed in an IP-
67 rated enclosure.
