PC/104-Plus – COM-1460 Module 17

J7, J8, J9 for Firewire

Each of the Firewire ports - compliant with the IEEE 1394 OHCI standard - is a high speed bus that supports data transfer rates up to 400Mbps (100/200/400 Mbps selectable) and delivers more than 30 times the bandwidth of the popular USB peripheral standard. Each of these ports can be used to connect up to 63 external devices, support “hot plug-and-play” and provide power supply to peripherals through an internal DC/DC converter (that is specifically used to isolate power between the physical layer and the host computer). The Firewire bus is Power Class 1.
