VEX-142 CR信息

产品详细说明:

The VXC-142 series card provides two RS-422/RS-485 serial ports. Each port can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication. It supports for speed up to 115200 bps and supports full-duplex communication.

Users may specify a COM port number manually by setting dip switch, or let the driver choose an available number automatically. The driver provides a maximum of 128 KB software FIFO for each COM port under Windows. It's practical for large file transmission.

The data lines of each serial ports on i version VXC cards come with photocouplers design. The on-board photo couplers use a short optical transmission path to transfer a signal between elements of a circuit, and keep the data lines electrically isolated. It can help cutting down on ground loops, common mode voltages and block voltage spikes, provide electrical isolation, and offer significant protection from serious over-voltage conditions in one circuit affecting the other.

In harsh industrial environments, the on-board ESD protection component (for i version) diverts the potentially damaging charge away from sensitive circuit to protects the computer and equipment from the sudden and momentary electric current.

The serial communication card are designed for use with intelligent devices like bar code reader, serial printers, intelligent sensors, instrumentation equipment, computers and almost any device with an RS-422/RS-485 port.

Note: The users using VXC-142U just need to reinstall the latest driver, regardless of modifying application program. back •Provides 2 RS-422/485 ports •Built-in COM-Selector •+/-4 kV ESD Protection •128 KB Software Buffer (max.) for Each COM Port Under Windows •2500 VDC Isolation for i versions •3 kV Isolated ports for VXC-142i •Short Card Design •128-byte Hardware FIFO for Each Port for VXC-142(i)(A)U •Supports 3.3 V/5 V PCI bus, Plug and Play for VXC-142(i)(A)U •Supports PCI Express, Plug and Play for VEX-142(i) •LED diagnostic indicators for VXC-142(i) •Supports 5 V PCI bus, Plug and Play for VXC-142(i) •16 bytes hardware FIFO for each port for VXC-142(i) back •Windows NT4/2000 drivers for VXC series. •Drivers for 32-bit Windows XP/2003/2008/Vista/7/8 •Drivers for 64-bit Windows XP/2003/2008/Vista/7/8 back •Industrial Machinery •Building Automation •Restaurant Appliances •Laboratory Equipment & Research •Industrial Communication back Models VXC-142 VXC-142i VXC-142(A)U VXC-142i(A)U VEX-142 VEX-142i Communication Port COM1 ~ COM4 RS-422/485 The RS-422 and RS-485 cannot be used simultaneously RS-422 TxD+, TxD-, RxD+, RxD-, RTS+, RTS-, CTS+, CTS-, GND RS-485 2-Wire Data+, Data-, GND Bias Resistor Yes, 1 KΩ Node 256 (max.)
