Abstract
PURPOSE:To extend transmission/reception modules with no influence of the memory capacity set at a data connecting part, by adding buffers as necessary at the data connecting part and at the same time transferring a display data transfer request to each transmission/reception module from a computer via a common bus. CONSTITUTION:The capacity of a transmission waiting buffer of a measurement/ transmission memory 20 is roughly decided by a data transmitting speed to a computer 1 and a data receiving speed from a data bus 6. However, the buffer 20 has an overflow if time control is not carried out at the data input side since the capacity of the buffer 20 is limited. Therefore, the transmission/ reception/reception modules 7 and 8 that received an entire data transfer request from the computer 1 send display data to the bus 6 with the time delay set by a time constant peculiar to each module. Thus the concentration of data can be avoided at a data connecting part 5.
