Mercury OTC-M Serial to CAN GPS Gateway Kit

Kit includes parts to add GPS to a MoTeC ECU equipped Mercury watercraft. The RaceGrade OTC-M converts serial data stream from a MoTeC L10 GPS into the M1 CAN Decode format. The serial connection will directly connect to a MoTeC L10 (38,400kbps) GPS device. This serial GPS data is converted onto CAN starting at base message ID 0x680 for decode by an M1 ECU. Additionally, the OTC-M provides the correct 5v power supply for these GPS devices.

• Kit contains both GPS-L10 and OTC-M

The GPS-L10 is a 10 Hz GPS which combines the electronics and antenna into one small unit. A highly sensitive receiver allows the GPS to lock onto signals even in difficult environments. It is fitted with a DTM connector and is pre-configured to be compatible with MoTeC Dash/Data Loggers. It is not compatible with MoTeC Mx00 ECUs. (See GPS-L5)

This unit is suitable for speed, position and lap timing.

Mounting

The GPS unit has an integrated antenna and should be mounted on an external horizontal surface that has a clear view of the sky. The unit should be mounted away from sources of interference including other antennas.

If mounting on a non metallic surface it may be necessary to add a metallic ground plane under the unit to improve the signal level. The ground plane should be at least 150 mm (6 in) square and may be made of aluminum or steel.
