RS232 and RS422 Interface Chip .
  • High-resolution eddy current sensor system
    The features are shown in Table 2 . This triggered device was combined with a multiplexer and a controlling unit. The electronic is connected to a LabViewTM interface via Ethernet, digital I/O ports and RS232 .
  • Performance measurements of superconducting current leads with low helium boil-off rates
    The software used to dis- play and record the data is Labview 2 (developed by National Instruments). All analog signals are routed to the multiplexer , which is connected to a qultifunction I/O board installed in the computer. RS232 signals (silicondiodes and measurement reservoir pressure) are routed directly to the computer's serial ports .
