Introduction 1 The RabbitCore RCM2100 series is a family of microprocessor modules designed to be the heart of embedded control systems. In addition to the array of I/O and addressing available on other Z-World products, the RCM2100 series offers an optional integrated Ethernet port. These modules permit LAN and Internet-enabled systems to be built as easily as serial communications- only systems. -
