Programming Tools
In-system-programming is an important aspect of the modern production processes. The programming tool UNICOM from CSM is optimized for fast flash programming. In addition it can also be used for communication tasks and functional tests. It provides versatile interfaces towards the attached target. A simple but powerful connection to the production equipment is used to control the tool.
Key Features
- Fast, reliable flash programming in a production environment
- Technical support by qualified engineers with application experience
- Long-term availability of hardware and software
- User-friendly licensing
- Universal hardware
UNICOM3
UNICOM3 is the modern version of the reliable UNICOM tools. It combines the successful principle with a powerful new hardware. It is designed to adapt custom-specific solutions quickly and cost-effectively by selecting from a comprehensive collection of generic software components.

Functional principle
UNICOM is used as an intelligent adapter between the production equipment (e.g. in-circuit-test or test computer) and the produced product (e.g. vehicle control unit). It is also an effective tool for developing, testing and validating of electronic control units.
UNICOM provides a RS232 interface as well as a USB port for the connection to the computer. The test computer controls of UNICOM by using command/response telegrams. All flash data to be programmed is stored in UNICOM and can be accessed during in the production process very reliable and fast.
As an OEM product intended for the integration into the production equipment, all interfaces are completely documented, including the communication protocol to the computer. UNICOM has a modular design and uses the same command/response format for all hardware interfaces and software components.
CSM offers individual, complete packages for project-specific solutions upon request. They consist of all software components, related documentation, connection diagrams and detailed example sequences. The package provides the optimum start position for the quick and smooth integration of the UNICOM solution in the production equipment of the customer.
