Will a haltech ic-7 dash work in a s300? I’m pretty new to the concept of a digital dash but have a lead on one for cheap

What input protocols does it use?

he S300 can output CAN packets for datalogging or other use. This is available from the CANL and CANH pins on the S300 digital connector.



Format: 11 bit, 250 kbps, big-endian

Speed: 100 Hz, cycling through the packets

The S300 does not have a CAN termination resistor.



MoTeC SDL/ADL: 500 kbps, same packet format

Sorry meant to post the following :

The IC7 software has the protocol for both Motec M1 and Motec 100 series. From the S300 details, it looks like it can out put directly to Dash via the Motec protocol.

Would be great to see if anyone could test this.
