Table 6-6 Checksum Example Error
In section 6.2.11 Table 6.6 we have an example of checksum usage.
It happens to use of a GET_COMMAND: STATUS_MESSAGES and shows in slot #24 a value of 0xFF for the paramater data STATUS_ERROR. HOWEVER the Status Type define for STATUS_ERROR is shown in Table A-4 as 0x04. How did I find this ?? A controller (by others) sent me a GET:STATUS_MESSAGES with 0xFF in the paramater data, which I rejected with a NACK: NR_DATA_OUT_OF_RANGE, since the only valid values (from Table A-4) are 0x00 thru 0x04. I suggest we review this (and other task group posts) in Dallas before making some of this knowledge public via this forum regards |
