Appendix  D

Sending Binary Data Over RS-232

About This Appendix

This appendix describes the procedure for sending pure binary data over an
RS-232 interface.  The formatting described is used in the

DIAG:DOWN:CHEC[:MADD]

, 

DIAG:DOWN:CHEC:SADD

, and

DIAG:DRIV:LOAD:CHEC

 commands.  This appendix contains the following

main sections.

Formatting Binary Data for RS-232 Transmission

The most straightforward way to send a block of data is to open the data
file, read the next byte from the file, and send it to the System Instrument
until you reach the end of file.  However, binary data cannot be sent to the
system instrument as is.  It must be converted into a format that will not
conflict with the special characters that the RS-232 interface recognizes.
This is done by sending only one half byte (a nibble) at a time.

To prevent this nibble from being confused with a special character, bit 7 of
the nibble is set to one.  This gives all data bytes in the block values greater
than 127 so they are not confused with ASCII characters.  It also doubles
the size of the file to be sent and the transmission time for the file.  Since a
transmission error that required re-transmission of the entire data block
would be very time consuming, a 3-bit error code (which allows for
correction of single bit errors) is added to the transmission byte.  The
following format is sent for each nibble:

Bit  #

7

6

5

4

3

2

1

0

1

Correction Code

Data

The error correction code is based on the nibble of data sent.  The easiest
way to implement this code is to use Table D-1.  It is indexed based on the
value of the nibble to send out, so there are 16 elements to the table.
