Abaco Systems / Radstone PME SIO-4 Serial Communications Controller

The Abaco Systems / Radstone PME SIO-4 is a serial communications controller designed for embedded systems, providing multiple serial ports for peripheral and device communication. This controller features sixteen independently programmable input/output channels, each driven by a Dual Universal Asynchronous Receiver/Transmitter (DUART). These channels are accessible via two 64-way connectors on the front panel and are configured for RS-232C communication. The PME SIO-4 interfaces with the host processor as 1 Mbyte of RAM mapped into the VMEbus memory map. Its onboard components include DIL switches for address selection and full VME interrupt generation and handling capabilities. As a slave device, it can be configured to respond in either the A24 or A32 address spaces via jumpers.
