The Moxa CP-602E-I-T is an industrial-grade PCI Express CAN interface card with two independent communication ports, designed for use in demanding environments. It supports CAN protocol standards 2.0A and 2.0B and enables integration of CAN-based systems into PC-based control and monitoring environments. The card is equipped with an NXP SJA1000 controller and a PCA82C251 transceiver, ensuring reliable bus arbitration, error detection, and data security. The galvanic isolation of 2 kV per port protects the card and the host computer from voltage spikes and potential differences, which is particularly important in industrial installations.

Applications include automation technology, machine building, vehicle technology, and other applications where CAN bus systems are used for communication between control devices and sensors. The card is designed for use in computers with a PCI Express interface and offers a compact form factor that can be integrated into standard PCs and industrial computers. The wide-temperature version CP-602E-I-T is designed for operating temperatures from -40 to +85 °C, making it suitable for use in extreme environments such as outdoor installations, cooling systems, or vehicles.

Functions and features in detail include two CAN ports with DB9 connectors (male), each equipped with LED indicators for transmission (Tx) and reception (Rx). These provide visual diagnostics and facilitate troubleshooting during operation. The transmission rate is user-adjustable and ranges from 10 kbps to 1 Mbps, allowing the card to be flexibly adapted to different requirements. An optional termination resistor of 120 Ohm can be activated per port to minimize signal reflections in the CAN bus.

Technology explained simply shows that the card features a robust hardware architecture based on proven components. The NXP SJA1000 controller handles CAN protocol processing, while the PCA82C251 transceiver provides the physical interface to the CAN bus. The galvanic isolation of 2 kV per port ensures that electrical disturbances or voltage spikes are decoupled from the host system. The LED indicators provide quick visual feedback on communication status, which is helpful during commissioning and maintenance.

Compatibility and accessories include support for Windows drivers and a DLL programming library with sample code, suitable for developers, system integrators, and OEMs. The card is compatible with the PCI Express bus.

Installation and mounting is done by inserting the card into a free PCI Express slot in the computer. Installation of drivers and software components is performed using the files provided in the delivery scope. The card requires no additional power connections, as it is powered via the PCI Express bus. The connections on the DB9 connectors are directly connected to CAN bus networks.

Operational advantages include high reliability, demonstrated by an MTBF of 4,645,502 hours (according to Telcordia SR332). The card complies with EMC standards such as EN 55032/35, CISPR 32, and FCC Part 15B Class B, as well as EMS tests including ESD, RS, EFT, Surge, and CS, confirming its suitability for use in electromagnetically harsh environments. Compliance with RoHS, CRoHS, and WEEE demonstrates the environmental compatibility of the product. The warranty period is 5 years.

The delivery scope includes: 1 × CP-602E-I-T card, 1 × Quick Installation Guide, 1 × Material Declaration, and 1 × Warranty Card. The card is designed for use in industrial environments and provides a stable, long-term solution for CAN communication over PCI Express.

The card is designed for use in systems with CAN bus technology, which is widely used in automation technology and machine building. The PCI Express interface enables fast and reliable integration into modern computer platforms. The galvanic isolation protects against electrical disturbances, and the wide-temperature version extends the range of applications to extreme environments. The LED indicators support diagnostics during operation. The software support for Windows and the provided development tools facilitate integration into existing systems.
