The PCI Express card by Delock expands a PC by two external serial RS-422/485 ports. Devices such as scanners, protocol converters, POS systems, infrared -, IoT - devices etc. and different modes can be used. The PCIe card supports 2- and 4-wire operation at both connections for RS-422 and RS-485 devices. In addition, the integrated terminating resistors can optionally be activated, thus avoiding unwanted signal interference. RS-422 or RS-485 settings The settings can be set with jumpers on the PCIe card and provide the modes Auto Detect, RS-422 and RS-485 4-wire full duplex and RS-485 2-wire half duplex operation. Low Profile Form Factor By using the included low profile bracket, the PCI Express card can be also installed into a Mini-PC. - Connectors: external: 1 x DB44 female connecting cable: DB44 male > 2 x serial RS-422/485 DB9 male internal: 1 x PCI Express x1, V2.0 - Chipset: MaxLinear XR17V352, SP3078E - Data transfer rate up to 1 Mbps - FIFO: 256 byte - Compatible with 16C550 UART - Data bit: 5, 6, 7, 8 - Stop bit: 1, 1.5, 2 - Parity: even, odd, none, mark, space - Flow control: XON / XOFF, RTS / DTR, CTS / DSR - RS-485 automatic half duplex data flow control - Protection for open, short-circuited or terminated input lines - Status LEDs: TX, RX - ±15 kV ESD protection on all signal pins (HBM) - ±15 kV IEC 61000-4-2 Air Gap Discharge - ±8 kV IEC 61000-4-2 Contact Discharge - I/O address and IRQ assigned by BIOS - Optional termination resistor 120 ohms System requirements - Linux Kernel 2.6 or above - Windows 8.1/8.1-64/10/10-64 - PC with one free PCI Express slot Package content - PCI Express card - 1 serial connecting cable - Low profile bracket - 4 x jumper - Driver CD - User manual Package - Box https://elecena.pl/product/19651102/90048-pci-express-card-to-2-x-serial-rs-422-485-with-15-kv-esd-protect 2021-10-18 https://elecena.pl/product/19651102/90048-pci-express-card-to-2-x-serial-rs-422-485-with-15-kv-esd-protect 2022-01-21 https://elecena.pl/product/19651102/90048-pci-express-card-to-2-x-serial-rs-422-485-with-15-kv-esd-protect 2022-09-14 https://elecena.pl/product/19651102/90048-pci-express-card-to-2-x-serial-rs-422-485-with-15-kv-esd-protect 2023-05-14 https://elecena.pl/product/19651102/90048-pci-express-card-to-2-x-serial-rs-422-485-with-15-kv-esd-protect 2026-03-04 https://elecena.pl/product/19651102/90048-pci-express-card-to-2-x-serial-rs-422-485-with-15-kv-esd-protect 2026-06-29
