More Dash


October 21 2007 - More Dash
Spent the day trying to wire everything up, total nightmare! Got the car just about driveable in the end, but don't have a speed reading, and have had to put in the old fuel gauge temporarily.

This is the email i sent to race technology .....

I have the DASH2, DL1 and CAN interface which i'm trying to make work with the MBE 992 / CAN.

I need a bit of help please! I'm at Snetterton on Saturday, so i'm desparate to get as much fixed as possible, my priority being Speed Display! These are my issues....

1. Don't know how to use the 'daisy chain' RS232 cable between DASH2 and DL1. I can get the PC to talk to both individually, and can get the DASH2 to talk to the DL1, but not the PC at the same time. Could you give me a wiring diagram? I'm beginning to think perhaps the cable is faulty, or i'm just misundetsanding what should be acheivable.

2. Fuel level - i have no idea how to get this working! It is a VDO sensor variable resistor to ground. Apparently i need a pull up resistor or something... but this is a bit beyond my knowledge, could you advise? I don't mind a trip to maplin if i know what to buy and how to wire it, but i'm drawing a blank currently!

3. Speed. I have 2 wires going to my VDO 'hall effect' gizmo. I've tried putting 5v down one and the other into the wheel speed, no luck. How should i wire this up?

3. CAN Interface. I've tried to configure just the first message ID 0 to grab the coolant temp from the MBE ECU. No luck at all. I can't tell if its even receiving anything - some sort of output showing serial communication would be handy.

4. Version of firmware on Dash2. I've tried flashing it, but it now doesn't work well - it crashes when it receives serial communication from CAN/DL1, and requires ignition off/on to come back. Where is the flash HEX v7 file for the Dash2? I think i need to try again.

Thanks in advance,
