【Summarize】
CAN232 is used for data exchange between CAN-Bus field bus
and RS-232 bus interface converter, and supports Modbus RTU
protocol. CAN232 interface converter integrated a RS-232
channel and a CAN-Bus channel can be easily embedded using
RS-232 interface for communication nodes, do not need to change
the original hardware architecture enables the device to obtain the
CAN-Bus communication interface, to achieve between the
equipments of RS-232 and CAN-Bus network connection and
data communication. RS-232 channel CAN232 devices to support
a variety of baud rate, the range is 300bps~115200bps. CAN-Bus
channel support CiA recommended a variety of standard baud rate
and user-defined baud rate, the range of 2.5Kbps~1Mbps.
CAN232 interface converter provides three types of data
conversion: transparent conversion, encryption conversion and
Modbus protocol conversion.
Its exterior design supports DIN-Rail mounting and Wall
mounting, which is convenient for engineering application. The
board comes with a photoelectric isolation module, complete
electrical isolation control circuit and CAN-Bus communication
circuit,
