VEX-112i
PCI Express, Serial Communication Board with 2 Isolated RS-232 ports. PCI-Express counterpart to VXC-112iAU.
Features
![Application Image of VEX-112i](images/VEX-VCX-112i_app.jpg)
The VEX-112 series card provides 2 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 VEX 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.
