Transmit any CAN data with Julie™

Have you ever needed to wake up an instrument cluster on the bench, simulate a missing control module, or test how an ECU reacts to specific CAN messages? If you are involved in automotive diagnostics, bench testing, or reverse engineering, you know how crucial it is to have a reliable way to inject custom CAN frames into a network.

Meet your new favorite tool: the Julie™ SEND DATA emulator.

While our standard Julie emulators come pre-programmed for specific immobilizer or ESL/ELV solutions, Julie SEND DATA gives the power back to you. It is a fully customizable, standalone device designed specifically to let you send whatever CAN data you want, whenever you want.

Why Choose Julie SEND DATA for CAN Injection?

Instead of relying on bulky PC interfaces and complex scripts just to send a cyclic wake-up frame, Julie SEND DATA acts as a tiny, autonomous node. Once programmed and powered on (whether in the car or on your test bench), it tirelessly broadcasts your custom CAN frames.

It is the perfect solution for:

• Bench Testing: Simulate ignition statuses to wake up dashboards, radios, or power steering racks outside of the vehicle.
• Module Simulation: Emulate the presence of missing or damaged components on the CAN network to clear faults or test ECU behavior.
• Custom DIY Solutions: Build your own permanent emulators for custom engine swaps or retrofits.
• Automated "Macros" & Startup Settings: If you know the specific CAN parameters for certain vehicle functions, you can use Julie SEND DATA to create a custom "macro." Program the emulator to execute a specific sequence of commands right after the car starts.

The Power of the Online Configurator

You don't need to be a programmer or a hex-code wizard to use Julie SEND DATA. We have built an intuitive, web-based tool that does all the heavy lifting for you.

With the Julie™ SEND DATA — BIN Configurator, you can easily configure up to 8 independent CAN frames. For each frame, you have total control over:

• Frame Type: Choose between Standard (11-bit) or Extended (29-bit) identifiers.
• CAN ID & Speed: Define your target identifier and match the vehicle's baud rate (e.g., 500 kb/s).
• Data Payload (DLC): Set the data length and input the exact hex bytes you want to transmit.
• Timing: Define the interval between sends (in milliseconds) and set the number of repeats (or set it to '0' for an endless loop).

Once you've set up your frames, the configurator provides a helpful summary and instantly generates a .bin file. All you have to do is download this file and write it to the 24C02 EEPROM memory on the Julie emulator using your favorite programmer!

See It in Action!

We know seeing is believing. We’ve prepared a video that shows the Online Configurator in use – how to write the file to the emulator, and see the CAN frames successfully broadcasted on the network.
