Industry Pack Modules Industry Pack Modules IP502 Serial 485 Communication These modules provide an asynchronous serial communication interface for your system. The IP502 has four asynchronous, half-duplex RS485 serial ports. It provides a cost-ecient interface to RS485 The IP502 provides a cost-eective interface to RS485 networks. A variety of features add exibility to handle more applications multi-driver networks which support up to 32 nodes. However, for full handshaking support, use the full- Environmental Specications Operating temperature: 0 to 70°C. duplex IP501. RS485 Serial Ports Storage temperature: -40 to 125°C.
