I-8120W-G CR ICP DAS CAN

The I-8120W has one CAN communication port with 5-pin screw terminal connector. It uses the NXP
SJA1000T and transceiver 82C250, which provide both CAN 2.0A and 2.0B specific, re-transmission
function, bus arbitration and error detection. Combining the benefits of PACs of ICP DAS without
increasing the CPU loading heavily, it could be a powerful multi CAN port programmable device
server by driving the program in the 186 CPU of the I-8120W. It can also communicate with other
kinds of communication interface, such as RS-232/RS-485/Ethernet ports to be a programmable
multi-interface device server.
