On connecting the Brake and Throttle to the Grin Baserunner

[H Franz]

I'm confused, I'm looking at the Baserunner's ‘Main9 Cable’ connector and I don't understand which pins to connect a normal brake ‘Brake power off’ connector (2 pins), and which pins to connect a normal throttle (3 pins).
Furthermore, I would like to know if it is possible, and to which pins on the ‘Main9 Cable’, to connect a third-party LCD display and use the button on the display to switch the controller on/off.
The same goes for the front light: is it possible to connect it and control it via the display?

The baserunner (and phaserunner, for that matter) do not directly support 3rd party displays. Gotta add a superharness for that.

There is a breakout cable for the mains that separates all of these out for you: 9 Pin Mains to Throttle and Ebrake Breakout Cable

Il baserunner (e il phaserunner, se è per questo) non supportano direttamente i display di terze parti. Devo aggiungere un superharness per quello.

C'è un cavo breakout per la rete che separa tutti questi per te: Cavo breakout da rete a 9 pin per acceleratore e Ebrake

Grazie, ho visto il cavo che separa i segnali dell'acceleratore e dell'e-Brake, ma non vedo il connettore per il display LCD. Come collegare un display di terze parti?

You can not. It does not support a 3rd party display. You can connect a Cycle Analyst, but that's all.

You can not. It does not support a 3rd party display. You can connect a Cycle Analyst, but that's all.

However, the indications are clear: the wiring with the superharness cable allows the main signal to be divided into throttle, brake and third-party display, etc.

Superharness is not really just a cable. It's a cable with a cycle analyst built in, but the cycle analyst's display has been removed.

3 Wiring Strategies

The Baserunner V6 has three supported hookup modes. It can be connectedunder the full control of a V3 Cycle Analyst, under the control of a 3rd partydisplay with a Superharness, or “headless” with no display at all.

The product page is, perhaps, a bit abbreviated. It *can* use alternate displays, but as Inanek noted, does require a superharness. You can't use any directly, is more what I'm saying.

And you can't use ANY 3rd party display, just the 3 special models Grin supports.

What you say made me suspect that these Grin-supported displays also have custom firmware, but reading on page 8:

3.2 Docking third-party displays with Superharness
The Baserunner V6 can be used with some third-party displays (King Meter, Star-Union, Superharness).

These appear to be standard displays, but have a specific communication protocol.

Grin has always said the non-superharness 3p display support is for business partners only last I checked. Did read one thread on it previously, though

I have one and it shows the grin logo on boot up so I assume custom ...
