FUN-E SNAIL

Summary

The Firmware Utility Network Exchange System for Non-Applied and Integrated Logistics (FUN-E SNAIL) is a PCB designed by the electrical team to make prototyping CAN networks easier. The board has a number of DB-9 connectors, which each support CAN high and low and 12V power, which can be used to power connected devices. Boards can be connected for testing using custom wire harnesses produced by the integration team.

Setup

The only setup that needs to be done to get the FUN-E SNAIL working is for whatever board you'd like to connect. For boards that use the standard EVT Ampseal connector, you can use one of our standard wire harnesses without modification. For an FTB, you'll need a wire harness that has only CAN high and low and that leaves the wires without a connector on the FTB's side because it will use the screw terminals. For any other boards, talk with the integration team to have them produce a wire harness for your application. If you'd like to connect a CAN dongle, like the PEAK, you'll need a gender switcher.

Use

To use the FUN-E SNAIL, unplug anything plugged into it, plug in the barrel jack, and flip the switches to enable all the ports you intend to use and disable the rest. The red LEDs indicate which ports are enabled. These switches only control power, so you can also disable any ports for devices that don't need 12V, as their CAN connection will still go through. Once you have the right ports enabled, switch the FUN-E SNAIL off and plug in all the devices you want on the network. When you're finished, switch the power back on.
