VXC-182iAU
Universal PCI Bus, Serial Communication Board with 1 Isolated RS-422/485 port and 1 RS-232 port (RoHS)
Features
The VXC-182iAU serial card is equipped with two communication ports: RS-422/485 and RS-232 port. It can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication. Both configuration supports speed up to 115200 bps allowing information to be transmitted over a long distance communication link.
Users can 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, allowing for large file transmission.
The data lines of each serial ports on i version VXC cards is designed with photo couplers. 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. This helps eliminate 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) protects the computer and equipment from the sudden and momentary electric current by preventing charge away from the circuit.
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.
