VXC-148U Universal PCI Serial Board, 8-Port RS-422/485

The VXC-148U/D2 CR is a universal PCI serial communication board that adds eight RS-422/485 ports to a computer. Each port has its own 256-byte hardware FIFO and supports full-duplex communication at up to 115200 bps, making it suited to engineers who need multiple serial links from a single PCI slot.The card supports both 3.3 V and 5 V PCI bus signalling and can assign COM port numbers automatically, or allow them to be selected under software control. Its short card design suits compact PC builds. Typical peripherals include bar code readers, serial printers, intelligent sensors and instrumentation equipment.Key specificationsConnector: female DB-62, supplied with a CA-PC62M D-Sub connector in the standard listingBaud rate: 50 - 115200 bpsData bits: 5, 6, 7, 8; stop bits: 1, 1.5, 2Parity: none, even, odd, mark, spacePower consumption: 120 mA @ 5 VThe price list description for this ordering code refers to a CA-9-6210 cable in place of the CA-PC62M connector, so check the included accessories against your cabling requirements before ordering.ApplicationsIndustrial machineryBuilding automationRestaurant appliancesLaboratory equipment and researchIndustrial communication

The VXC-142iAU CR adds two RS-422/RS-485 serial ports to a PC through a universal PCI slot. Each port can be set to RS-485 for half-duplex or RS-422 for full-duplex operation, with speeds up to 115200 bps.The i version isolates the data lines with on-board photocouplers, keeping the serial channels electrically separated from the host. This helps reduce ground loops and common-mode voltage problems, and the 2500 VDC isolation and ±4 kV ESD protection add robustness where electrical noise and voltage spikes are a concern.COM port numbers can be fixed with an 8-bit DIP switch or left to the driver, which assigns an available number automatically. Under Windows the driver provides up to 128 KB of software buffer per port, backed by a 128-byte hardware FIFO, which suits large file transfers.ApplicationsIndustrial machineryBuilding automationRestaurant appliancesLaboratory equipment and researchIndustrial communication

The VXC-112AU CR is a short-card universal PCI board that adds two RS-232 serial ports to a host PC. It suits engineers who need dedicated serial connections for bar code readers, serial printers, intelligent sensors and instrumentation that communicate over RS-232.Each port has a 128-byte hardware FIFO and supports full-duplex communication at up to 115200 bps. The card works with both 3.3 V and 5 V PCI bus signalling. COM port numbers can be set manually using the built-in 8-bit DIP switch COM-Selector, or the driver can assign an available number automatically. Under Windows, the driver provides up to 128 KB of software buffer per COM port, which helps with large file transfers.Each port's data lines are standard RS-232 with no isolation on this variant. For isolated and ESD-protected data lines, the i versions of the VXC-112 series, such as the VXC-112iAU, should be considered. The board is rated for 0 ~ +60°C operation and is CE, UKCA, FCC, RoHS and WEEE listed.ApplicationsIndustrial MachineryBuilding AutomationRestaurant AppliancesLaboratory Equipment & ResearchIndustrial Communication

VXC-114U CR is a universal PCI serial communication board that adds four RS-232 ports to a host PC. It suits engineers who need to connect several serial devices such as bar code readers, serial printers, intelligent sensors and instrumentation to a single computer.Each port has a 128-byte hardware FIFO and supports baud rates from 50 to 115200 bps with full-duplex communication. Under Windows, the driver provides a software buffer of up to 128 KB per COM port, which helps with large file transfers. The COM port number can be set manually with the built-in 8-bit DIP switch selector, or left to the driver to assign automatically.This is the non-i version of the card, so the isolation and ESD protection features are those of the i versions and are not part of this model. The board supports 3.3 V and 5 V PCI bus signalling and uses a short card design. One CA-4002 connector is included.ApplicationsIndustrial MachineryBuilding AutomationRestaurant AppliancesLaboratory Equipment & ResearchIndustrial Communication
