C25 : DPR-119 DIAG INFO
This function informs the result of the self-diagnosis of the
DPR-119 board of BKNW-118. It is displayed when the
BKNW-118 option is installed.
When a failure occurs on the DPR-119 board, this function
guess the default IC but do not specified.
n
“ERROR” may be displayed as the diagnosis result even if
the boards except DPR-119 are defective.
An initialize check and something check are available as
the self-diagnosis function.
. In the initialize check, check the communication of the
communication bus (PAD0-7, STAT0-1, STRB, and CS)
between SY2 CPU on the SS-83 board and IC213 or
IC216 on the DPR-119 board.
Initialization data is transferred from SY2 CPU to each IC.
After that, the initialization data set in each IC is read and
compared with the initialization data transferred at first.
. In the something check, a parity check and FIFO memo-
ry check are performed for the input signals of IC200,
and the result of the self-diagnosis of IC200 is displayed
by reading from SY2 CPU on the SS-83 board.
