tM-7530A Intelligent Tiny UART/CAN Converter, CAN 2.0A/2.0B

I-7530A-G bridges serial devices and CAN bus networks. Its single COM port can be set to RS-232, RS-485 or RS-422, and CAN messages are passed on to the serial side, so legacy equipment can take part in CAN-based control and monitoring without changes to the devices themselves.The converter is compliant with CAN 2.0A/2.0B and ISO 11898-2 and supports CAN baud rates from 10 k to 1 M bps. CAN and serial communication parameters are software configurable. Galvanic isolation (3 kV DC-to-DC and 2500 Vrms photocoupler on the CAN side) protects the serial equipment from faults arriving over the CAN network.A hardware watchdog helps the unit recover from disturbances in harsh or electrically noisy environments. Power, data and error LEDs show operating status, and the DIN-rail housing with a -25 ~ +75 °C operating range suits industrial control cabinets.ApplicationsConnecting RS-232, RS-485 or RS-422 devices to CAN bus networksControl and monitoring systems that combine diverse serial and CAN communication devicesIsolated serial-to-CAN integration in industrial cabinets

tM-7530 CR is a small RS-232 to CAN converter for engineers who need to link serial devices to a CAN network in a confined space. It supports CAN 2.0A and CAN 2.0B to ISO 11898-2, with CAN baud rates from 10 kbps to 1 Mbps including user-defined rates, and RS-232 rates from 110 bps to 230400 bps.The module is isolated on both the power side and the CAN bus side, with 3000 VDC isolation for DC-to-DC and 2500 Vrms for photo-coupling. Its function is fully compatible with the I-7530 and I-7530T, and it adds a listen-only mode for monitoring CAN traffic and detecting errors without transmitting. Communication parameters are set in software, and LED indicators show power, data flow and errors on both sides.Pair connection mode allows a PC and other RS-232 devices to be served at the same time, with user-defined end-of-character handling. Software buffers on both the CAN and RS-232 sides, a watchdog and time stamp responses on the RS-232 side add robustness for continuous operation.ApplicationsConnecting RS-232 devices to CAN bus networksMonitoring and error detection on CAN bus systems using listen-only modeConnecting a PC and other RS-232 devices at the same time via pair connection modeSpace-constrained control and monitoring installations across industries

The tM-7565 CR is a compact USB to CAN converter for engineers who need a laptop or PC to talk to a CAN network in a confined space. It complies with CAN 2.0A and 2.0B and ISO 11898-2, and supports CAN baud rates from 10 k to 1 M bps, including user-defined rates. Its functions are fully compatible with the I-7565.Power is taken from the USB connection, and both the power side and the CAN bus side are isolated. A selectable 120 Ω terminal resistor is built in, and communication parameters for both the CAN and USB sides are set in software. Software buffers on each side and an internal watchdog support stable operation.Listen-only mode lets the converter monitor CAN bus traffic and detect errors without transmitting. Pair connection mode allows two PCs to communicate with each other via USB, with a user-defined end-of-characters setting. The unit mounts on DIN-rail and is supplied with a CA-USB18 1.8 m cable.ApplicationsConnecting a laptop or PC to a CAN network where space is limitedMonitoring CAN bus messages and error conditions in listen-only modeCommunication between two PCs via USB in pair connection mode

The I-7530-FT-G CR bridges RS-232 and CAN networks, letting a PC, HMI or serial controller exchange messages with CAN devices without a dedicated CAN interface card. It supports CAN 2.0A and CAN 2.0B and conforms to ISO 11898-3 low speed fault tolerance, with CAN and RS-232 parameters set in software.Designed for industrial installations, the converter includes a hardware watchdog that resets the unit to keep it running in harsh or electrically noisy environments. Power, data flow and error LEDs for both the CAN and RS-232 sides help with commissioning and fault finding. Transparent communication mode is supported, and the CAN and RS-232 receive buffers hold 1000 and 900 frames respectively.Note that full-duplex communication with RS-232 devices is not supported. The unit operates from +10 VDC to +30 VDC, runs between -25 and +75 °C, and mounts on a DIN-rail in a plastic housing.ApplicationsConnecting PCs or HMIs to CAN bus devicesIntegrating RS-232 embedded controllers into CAN networksMonitoring and control of CAN devices from serial-equipped hostsIndustrial control and monitoring systems
