The JCOM1939 Monitor Software is a comprehensive Windows application developed by Copperhill Technologies, designed to monitor, record, analyze, and simulate SAE J1939 data traffic. It serves as an essential tool for professionals and enthusiasts working with Controller Area Network (CAN) protocols, particularly in heavy-duty vehicle networks.​

Key Features:

• ECU Simulation Setup: Users can configure Electronic Control Units (ECUs) by setting parameters such as preferred node addresses, negotiable address ranges, and NAME fields. This feature facilitates the simulation of ECUs, including full node address negotiation capabilities.​

• PGN Filtering: The software allows filtering of specific Parameter Group Numbers (PGNs) for display. Users can input desired PGNs and assign descriptions, enabling focused monitoring of relevant data traffic.​

• PGN Transmission: Users can design and transmit J1939 PGNs, either as single-shot messages or at assigned frequencies. This includes the ability to create request messages and define responses, enhancing the simulation and testing of network communications.​

• Analog and Digital Signal Simulation: The software supports the simulation of both analog and digital signals. Users can modify byte data through text input or sliders for analog signals and utilize checkboxes for digital signal manipulation.​

• Network Scanning: The network scanner feature enables users to identify active nodes within a J1939 network. By sending a "Request for Address Claimed" message, the software detects and displays information about other ECUs, including their node IDs and NAMEs.​

• Data Recording: The recorder function allows the storage of received PGNs into MS-Excel-compatible CSV files. This facilitates detailed analysis and documentation of network traffic over time.​

Hardware Compatibility:

The JCOM1939 Monitor Software is designed to work seamlessly with Copperhill Technologies' SAE J1939 gateways, including:​

• SAE J1939 Starter Kit and Network Simulator: This kit enables monitoring, simulation, and recording of any PGN as defined in the SAE J1939-71 standard, including diagnostic messages. It's ideal for users aiming to simulate specific diesel engine parameters by entering relevant PGNs.​

• SAE J1939 ECU Simulator Board with USB Port: A high-performance, low-latency vehicle network adapter that allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with the vehicle network. It supports the full SAE J1939 protocol, including network management and transport protocols.​

• SAE J1939 to Bluetooth Gateway Module: A wireless vehicle network adapter that enables any host device with a Bluetooth COM port to monitor and communicate with the SAE J1939 vehicle network. It features an external antenna to ensure optimal transmission quality.​​
