SKU 3575

The I-7530A-MR is helpful for data exchanging between the RS-232/485/422 devices and the CAN devices. It supports three communication modes: “Normal”, “Modbus RTU”, “Pair-connection”.

In the Normal mode, the I-7530A-MR is designed to unleash the power of CAN bus via RS-232/485/422 communication method. It accurately converts ASCII format messages and CAN messages between RS-232/485/422 and CAN networks. This mode let you to communicate with CAN devices easily from any PC or programmable devices with RS-232/485/422 interface.
In Modbus RTU mode, it allows a Modbus RTU master to communicate with CAN devices on a CAN network. The following figure shows the application architecture of this mode.

  • RoHS Design
  • Fully compatible with ISO 11898-2 standard
  • Programmable CAN bus baud rate from 10 kbps to 1 Mbps or user-defined baud rate
  • Support CAN bus acceptance filter configuration
  • Support firmware update via RS-232
  • Provide utility tool for module setting and CAN bus communication testing
  • Built-in jumper to select 120Ω terminator resistor
  • CAN buffer: 128 data frames ; UART buffer: 256 bytes
  • Power, data flow and error indicator for CAN and UART status
  • Hardware Watchdog design
  • Convert CAN message to specific ASCII command string (Normal mode)
  • Convert specific ASCII command string to CAN message (Normal mode)
  • Provide the transparent communication between the RS-232/485/422 devices via CAN bus (Pair-connection mode)
  • Support function code 0x03/0x04/0x10 of Modbus RTU command for reading and writing CAN message (Modbus RTU mode)
