Data rates on every port are up to 1Mbps in RS-232 mode, and 10Mbps in RS-422 and RS-485 modes. The board’s serial protocols are selected via software controlled GPIO lines built into the UART or on-board jumpers. I/O signals are provided on two miniature connectors with 2 ports per connector.
The DS-MPE-SER4M serial port PCIe MiniCard is a significant product introduction for Diamond Systems. Because PCIe MiniCard is becoming pervasive due to its small size and lost cost, it makes sense for Diamond, an I/O-focused company, to offer products in this form factor. This 4-port serial module is the first in what we plan as a series of high quality, cost competitive PCIe MiniCard I/O modules from Diamond.
