The VXC-114 series card provides 4 RS-232 serial ports. It is

equipped with a 128-byte hardware FIFO for each port, 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-232 port. back •Provides 4 RS-232 ports •128-byte Hardware FIFO for Each Port •Built-in COM-Selector •128 KB Software Buffer (max.) for Each COM Port Under Windows •+/-4 kV ESD Protection for i versions •Short Card Design •2500 VDC Isolation for i versions •Supports 3.3 V/5 V PCI bus, Plug and Play for VXC-114(i)U •Supports PCI Express x1, Plug and Play for VEX-114(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-114U VXC-114iAU VEX-114 VEX-114i Communication Port COM1 ~ COM4 RS-232 (TxD, RxD, RTS, CTS, DTR, DSR, DCD, RI, GND) UART 16C950 compatible Baud Rate 50 ~ 115200 bps Data bit 5, 6, 7, 8 Stop bit 1, 1.5, 2 Parity None, Even, Odd, Mark, Space FIFO Internal 128 bytes Isolated - 2500 VDC - 2500 VDC ESD Protection +/-4 kV - +/-4 kV General Bus Type Universal PCI, 3.3 V and 5 V, 33 MHz, 32-bit, Plug and Play mechanism PCI Express x1, Plug and Play COM-Selector Yes (8-bit DIP switch) Connector DB-37 (Female) Power Consumption 120 mA @ 5 V 880 mA @ 5 V 120 mA @ 5 V 880 mA @ 5 V Operating Temperature 0 °C ~ +60 °C Storage Temperature -20 °C ~ +70 °C Humidity 0 ~ 90% RH, non-condensing Dimensions (L x W x D) 142 mm x 84 mm x 22 mm 133 mm x 93 mm x 22 mm
