Danfoss 11153051 CG150-2 CAN USB INTERFACE

The Danfoss 11153051 CG150-2 is a professional-grade CAN USB interface module designed for real-time communication between CAN bus networks and host computers via USB connectivity. HVAC technicians, refrigeration engineers, and industrial automation professionals use this interface to configure, monitor, and diagnose Danfoss electronic controllers and drive systems in the field. This device solves the critical problem of establishing reliable bidirectional communication with Danfoss equipment without requiring proprietary hardware, enabling faster troubleshooting and system optimization across commercial and industrial cooling applications.

Product Overview

The Danfoss CG150-2 CAN USB Interface functions as a protocol bridge that converts CAN (Controller Area Network) bus signals into USB data packets compatible with Windows-based diagnostic and configuration software. The device features galvanic isolation between the CAN bus and USB interface, protecting sensitive computer equipment from voltage spikes and ground loop issues common in industrial environments. This isolation, combined with integrated CAN transceiver circuitry and USB 2.0 high-speed communication, ensures stable data transmission at CAN bitrates up to 1 Mbps while maintaining compliance with ISO 11898 CAN specifications.

The CG150-2 model specifically supports Danfoss AK-CC series controllers, ETS series compressor units, and VLT frequency drive systems through native CAN protocol implementation. Its compact form factor with integrated LED status indicators provides immediate visual feedback on communication status, CAN bus activity, and power supply conditions. The interface requires no external power supply as it draws operating current directly from the USB host connection, eliminating the need for additional power infrastructure in field service scenarios. Professional-grade construction with conformal coating and reinforced connectors ensures reliable operation in challenging environments including high-temperature plant rooms and moisture-prone cooling installations.

How to Use

Begin by connecting the Danfoss CG150-2 interface to your host computer via an available USB port. Windows will automatically detect the device and install required drivers from the system device database. Once detection is complete, connect the CAN bus connector to your Danfoss controller or drive system using either the 9-pin D-Sub or M12 A-coded connector depending on your equipment configuration. Verify proper connection by observing the green USB power LED and the CAN activity LED which should flash when the connected device is transmitting data on the bus.

Launch your Danfoss diagnostic software such as AK-CC Service Tool or VLT DriveWindow and select the CG150-2 interface from the communication device list. Configure the CAN bitrate to match your equipment setting, typically 250 kbps for most commercial HVAC systems or 500 kbps for industrial drive applications. Once communication is established, you can read real-time parameters, modify configuration settings, retrieve historical alarm logs, and perform system diagnostics. Always verify that the CAN network termination resistors are properly installed at both ends of the bus before establishing communication to prevent signal reflection errors.

Frequently Asked Questions

Is the Danfoss CG150-2 compatible with non-Danfoss CAN devices?

The CG150-2 is specifically designed as a Danfoss proprietary interface and works exclusively with Danfoss controllers, drives, and equipment that implement Danfoss CAN protocol specifications. While the device uses standard ISO 11898 CAN physical layer, the message format and parameter definitions are proprietary. For communication with third-party CAN devices, you would require a generic CAN USB interface that supports standard CANopen or J1939 protocols.

What is the maximum cable length between the interface and CAN device?

Standard CAN bus specifications allow cable lengths up to 40 meters at 1 Mbps bitrate, extending to 500 meters at 125 kbps. For the Danfoss CG150-2, we recommend using shielded twisted-pair CAN cable with 120-ohm characteristic impedance and keeping cable runs under 30 meters in industrial environments with high electromagnetic interference. Always ensure proper grounding of the cable shield at one end only to prevent ground loop currents.

Can I use the CG150-2 with older Danfoss controllers that use serial RS-485 communication?

No, the CG150-2 is exclusively a CAN bus interface and cannot communicate with legacy RS-485 serial devices. Danfoss controllers manufactured before 2005 typically used serial RS-232 or RS-485 protocols. For those older systems, you would need a Danfoss serial communication interface module. Check your equipment documentation for the communication protocol type before purchasing this interface.

Does the interface support simultaneous connection to multiple CAN devices?

Yes, the CG150-2 connects to the CAN bus network, which by design supports multiple devices on a single cable. You can connect up to 110 CAN nodes on a properly terminated bus, allowing simultaneous communication with multiple Danfoss controllers and drives through a single interface. However, the software application must support multi-node communication and you must configure unique CAN node IDs for each device.
