Industry Pack Modules Industry Pack Modules IP512-x Isolated Serial 485 Communication IP512 Industry Pack (IP) modules provide an isolated, high-performance serial communication interface for your computer. Large 64-byte FIFO buffers reduce the processing burden on the CPU to increase the overall system performance. Large FIFO buffers on the transmit and receive lines of each serial port enable more efficient data processing. Environmental Specifications When the buffer is full, an interrupt is sent to the Operating temperature: 0 to 70°C CPU to read the data. To match your budget and Serial Ports Storage temperature: -40 to 125°C. Configuration: 4 independent, isolated, RS485 ports. performance requirements, you can order 16 or 64-byte Relative humidity: 5 to 95% non-condensing. (IP512-16/64) buffers.
