Industry Pack Modules IP511-x Isolated Serial 422 Communication IP511 Industry Pack (IP) modules provide an isolated, asynchronous serial communication interface for your computer system. 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, full-duplex, performance requirements, you can order 16 or 64-byte Relative humidity: 5 to 95% non-condensing. RS422B ports. (IP511-16/64) buffers. Power: Interface: Asynchronous serial only. +5V (±5%): 160mA maximum. Data rate: Programmable to 512K bits/second. Consult factory Features ±12V (±5%): 0mA (not used). for custom baud rates up to 1M baud. ■Four asynchronous RS422B ports MTBF: Consult factory. Character size: Programmable 5-8 bits. ■Isolated serial ports Parity: Programmable odd, even, or no parity. Ordering Information Stop bits: Programmable 1, 1-1/2, or 2 bits.■16 or 64-byte FIFO buffers Industry Pack Modules Data register buffers: Double-buffered (16C450 mode) or ■Programmable baud rate (up to 512Kbps) IP511-16 16/64-byte FIFO buffered, Four RS422B ports with 16-byte FIFOs.
