| The Manual on the adapter of analog input IC539AI programm's configuring for several of multiplexers IC538MA using | The adapter IC539AI is worked under two PDP-channels (transmitting and receiving). For this purpose in the system RAM there are two buffers (both parameters for the transmitting channel and outcome for receiving.
The buffer of parameters for each measurement contains 4 bytes (0... 3), in which is set the task for the adapter. Detaily, in the byte number 1 is resulted the information about the channel which should be connected to ADP (numbers 0... 2 bits) and one is presented the multiplexer channel (0... 7); the bit 3 is defined group of the multiplexers (0... 7 or 8... 15), the bits 4... 6 is defined the multiplexer which is situated in group.
The buffer of an outcome accepts an outcome of a measurement from the adapter as two bytes. First two bytes of an outcome is corresponded to the first 4 buffer parameters' bytes etc. There are number of the channel and number of the multiplexer are set arbitrary in the parameters buffer . I.e. for the first measurement it is possible to set, for example, 15-th multiplexer with the 6-th channel enabling , for the second 2-nd one is set multiplexer with 3-rd channel enabling etc. The outcome is kept in the buffer as 12-bit code. The user program is been to take this code from PC memory and to enumerate under the correction factors from the .CLB extension. file. | | [Frage] |
| Charge of entering ISO-AD32(H,L) has FIFO 1Kbyte. They limited time of registrations (record) signal? | | FIFO needed for the agglomeration of result, and at all does not influence upon the velocity of work. | | [Frage] |
