tM-7530 Intelligent Tiny RS-232/CAN Converter with Pair Connection Mode

I-7530-G is an RS-232 to CAN converter that lets a PC or any device with a serial port exchange messages with CAN devices. It handles conversion between the two networks, so serial hosts can monitor and control CAN nodes without a dedicated CAN interface.The CAN port is compatible with CAN 2.0A and 2.0B and conforms to ISO 11898-2, with a jumper-selectable 120 Ω terminal resistor. CAN and RS-232 communication parameters are set in software, and transparent communication mode is supported. The CAN side provides 3000 VDC isolation, helping to protect the RS-232 equipment from faults on the CAN network.A built-in watchdog monitors operation, and power, data flow and error indicators show the status of both interfaces. The module has a 1000-frame receive buffer on the CAN side and a 900-frame buffer on the RS-232 side. Full-duplex operation of RS-232 devices is not supported. Installation is on a DIN-rail in a plastic housing, with an operating range of -25 ~ +75 °C.ApplicationsConnecting PCs or HMI hosts to CAN device networks over RS-232Linking RS-232 programmable controllers and embedded controllers to a CAN networkMonitoring and control of CAN devices in industrial automation systems

The tM-7530A CR bridges serial UART devices and CAN bus networks in a small DIN-rail housing, suited to panels where space is limited. It is designed to ISO 11898-2 and handles both CAN 2.0A and CAN 2.0B frames, with user-defined CAN baud rates as well as preset rates across the 10 k ~ 1 M bps range.Beyond straightforward protocol conversion, the unit offers a listen-only mode for monitoring CAN traffic and detecting errors without transmitting, and a pair connection mode that lets a PC and other UART devices share the link. CAN and UART parameters are set in software, and a selectable 120 Ω terminal resistor is built in. Its functions are stated to be fully compatible with the I-7530 and I-7530T.Power and CAN bus sides are isolated, and a watchdog and separate status LEDs for power, data flow and errors support straightforward commissioning and fault finding. The operating range of -25 ~ +75 °C suits typical industrial enclosures.ApplicationsConnecting UART or serial devices to a CAN networkMonitoring CAN bus messages and detecting errors in listen-only modeSharing a serial link between a PC and other UART devices in pair connection modeInstallations with limited space in control cabinets

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
