The SafePilot CAT v4 series is a wireless connection between the AIS pilot plug and a portable piloting display, with the added benefit of a rate gyro and microprocessor to improve the standard data coming from the AIS pilot plug. This method facilitates the addition of decimal degrees to the heading information, as well as good quality ROT (Rate Of Turn) data. An advanced internal program handles the calculations, providing a reliable inertial platform needed for crucial positioning predictions; this being especially important in critical turns. It is common knowledge that very often the...

Operating the CAT ROT Place the CAT ROT on a horizontal surface where it can be left and not moved during operation. It is important that the CAT ROT is horizontal and not moved during operation since this will interfere with the Rate Gyro computations. Connect the cable between the AIS pilot plug and the CAT ROT and turn on the CAT ROT by pressing the power button. When connected to an AIS plug the unit will flash blue until it receives AIS NMEA data and then it will emit steady blue. A steady blue light indicates that the CAT ROT is working properly. Now you can connect to the Wi-Fi...

Wireless Interface Wi-Fi The CAT ROT has got an IEEE 802.11 b/g/n Wi-Fi interface that complies with the FCC, IC, ETSI, TELEC, Wi-Fi standards. The range of the Wi-Fi is >200m with a clear line of sight. On a ship with a lot of metal structures this range cannot be achieved but if the unit is placed on monkey island it will cover the entire bridge. One thing that can reduce the range of the Wi-Fi is if the windows have built in heat. The CAT ROT / I / XT work by default on Wi-Fi channel 11. It is possible to change this channel in case there is a lot of traffic on this channel in the...

AIS Pilot Plug Mode AIS Pilot Plug The CAT ROT/XT connects to the AIS pilot plug with the supplied cable. The cable has got a standard plug used for pilot plugs and a SafePilot specific connector at the other end. The USB cable on this Y-cable is used for charging and it can be done while the unit is in operation onboard the vessel. Sometimes the installation of the AIS transponder do not follow the wiring standard on the pilot plug, and this can mean opposite polarity on the data wires as well as using other pins in the plug. The SafePilot CAT ROT/XT units take care of this automatically...

CAT I/XT in GPS Mode The GPS antenna is located below the cross on the lid of the unit. Do not cover this during operation, as this will affect the performance and accuracy of the GPS in backup mode. Avoid placing the unit nearby large objects when the unit is in GPS mode, as this may give unwanted shadows or reflections resulting in poor GPS stability. Avoid locations nearby ships’ transmitting antennas and radar scanners. GPS Data Format The data format from the CAT I/XT(GPS) is standard NMEA messages. It provides NMEA GGA, VTG, GSA and GSV Here you find an example of the data format. UDP...

Charging the Unit The charger provided is a USB charger capable of outputting 5V, 2.0A. It will charge the CAT ROT/I/XT from a flat battery in 5 hours. Using another charger is not recommended and we cannot guarantee the charge time. When the CAT ROT is connected to a charger and it is charging it will flash red. Once fully charged it will emit steady red. If the CAT ROT/XT is out of power you can connect it to a PC that is capable of providing 5V 0.5A on the USB port. This is enough for the CAT ROT/XT to operate and it will also be charging. The internal battery is a Lithium Ion battery...
