xRSUNI range offers high reliability, simplicity of installation and unequalled performances whatever your PCI computer owns a +3.3VDC or +5VDC bus power supply and whatever it is a standard or a low profile model.

They are designed to be installed in machines whose CPU is not overloaded or for real time applications when the time latency for signals control or characters sending is very critical.

xRSUNI boards uses communication controllers of last technology (silicon built-in 32 bits PCI Interface and UART), 128 bytes buffer for each receive and transmit channel. These features make it possible to reduce the host CPU load by more than 75% compared with the traditional solutions and allow the card to reach a 1,8 Mb/s data rate on each channel.

This communication solution is perfectly suited "Point of Sales" applications in order to connect tickets printers, scanners, bar code readers, cash registers and all other peripherals used in this area.
However, xRSUNI cards can be used in industrial applications to connect sensors, measurement systems, automats and all other serial peripherals used in the field of automation.

The xRSUNI range feature a very high level of protection against electrostatic discharges and overvoltage.
Its exceptional MTBF (10e6 POH) enables us to practise for all the products of this range a lifetime warranty (except isolated model).
