I am trying to daisy chain 2 Innovate MTX gauge together.
Innovate technical page says... to connect the out cable to the in cable of the next gauge.
I tried to make the 4 pin cable. Does anybody knows if I should swap the pin 1 out to pin 2 in ?

I cannot seems to find any info on the pin-out. Any help would be appreciated.

Assuming the out plug is

1 - tx
2 - rx
3 - gnd
4 - gnd

In plug

1 - rx
2 - tx
3 - gnd
4 - gnd.

 

Oldish thread I know, but did you have any luck with this?

I'm wanting to connect three gauges together to use them with the data logger, but the cables are 4 foot long, and my gauges are mounted in a smallish jiffy box, so an extra 8 feet of cable isn't going to work!

thanks!

 

this is in the manual...

3. Serial Out
1 RX
2 TX
3 GND
4 GND

4. Serial In
1 TX
2 RX
3 GND
4 *MTS Sense

but I dont know what the MTS Sense pin does? or what needs to be done with it?

edit:

cables are simply pin to pin...

so, pin 1 to pin 1, pin 2 to pin 2 etc.

you need to connect the MTS Sense to ground for it to be enabled, which is what happens when you connect pin 4 to pin 4
