The Eurotech COM-1274 is a fully RoHS compliant PC/104 module specifically
developed forperforming advanced communication tasks in embedded
systems.
It features 8 independent asynchronous serial channels and up to two Control
Area Network (CAN)ports. For flexibility and high-speed transmission, the
board’s 16C550C serial ports operate at up to115 Kbaud and are configured
in pairs via software as RS-232, RS-422 or RS-485.
The CAN interface supports the “CAN extended frame” mesasge format (CAN
2.0B protocol).
In order to meet the demands of high reliability in industrial environment, an
optically isolated RS485physical CAN interface option is available.
