The industrial router are designed for stationary applications. Often these routers are mounted on a DIN rail. Beside multiple LAN and WAN communication capabilities they provide means for data acquisition, protocol conversion or local data processing and storage. Applications include CCTV, Digital Signage, remote management and condition monitoring.

Dexcel’s Multifunction Signal Conditioning Card offers 16 analog and 20 digital isolated channels along with 4 isolated Analog Outputs and 8 Potential Free Digital Outputs. Analog Outputs and Inputs are capable of source and measure 4 – 20 mA of current. This card can be interfaced to the PC or data logging equipment using redundant RS-232 interfaces. This card is also capable of doing 4 channels RS232 to RS485 conversion.

Application : Signal Conditioning and Data Acquisition in Industrial Applications. and Industrial Control Systems.

The glue logic designed in the FPGA reads the serial data from both the inputs using the serial clock and converts the serial data into 64-bit parallel words. A frame sync sequence is detected to determine the start of the input serial data frame. The converted parallel data is buffered on the onboard FIFOs. The size of the FIFO depends on the serial data rate and the latency of the data transfer to the PC. Using DMA transfer the FIFO contents are transferred to the PC RAM. The special software application transfers the data from PC RAM to the PC hard disk. The design ensures no loss of data in the process of transfer from the serial inputs to the storage device.

Application : systems using PC for storage. and Geological and weather data collection systems
