The BS/Ex-LP is a low profile x1 lane, PCI Express serial card offering eight ports of RS-232/422/485 connectivity, compatible with any PCI Express slot. Bi-directional data speeds up to 7.8 Mbps (RS-422/485) ensure your data acquisition, office automation, POS, self-service kiosk or scientific/instrumentation applications communicate in a reliable, cost-effective manner.

BS/Ex-LP is compatible with x1, x4, x8 and x16 lane PCI Express slots. Upgrading a PCI system to the more efficient PCI Express requires a hardware change only – your new PCI Express system is backwards compatible with PCI software.
