See the following table for each "Error information" display and its explanation (status).
Display order is q , w , e , r , t , y , u
Condition
Compared with the destination setting on the
q
board. This is displayed when the model name
Firm Check
or destination information written into the
NG
firmware does not match. ( b )
w
No response from SUB microcomputer.
SUB NG
An error occurred in testing writing data
e
between IP SCALER and DDR.
IP SCALER

Testing writing data between IP SCALER and
DRR resulted in no response.
r
Error occurs in GUI version and Main μ-com

t
No response from DIR
DIR NG
When DSP code boot is performed, the DSP
FLAG0 port does not change to "H" even if
DSP reset is executed.
Before DSP command is issued, the DSP
BUSY port does not change to "L".
When DSP data read is performed, executing
WRITE="L" does not result in ACK="H".
y
When DSP data read is performed, executing
DSP NG
REQ="L" does not result in ACK="L".
When DSP data writing is performed,
executing WRITE="H" does not result in
ACK="H".
When DSP data writing is performed,
executing REQ="L" does not result in
ACK="L".
u
Error occurs in EEPROM checksum.(*** is a
EEPROM
block address number.)
NG
b
The written Firmware and product settings
(model name, brand name, destination) are
compared. If Firmware that is not designed
for this product is written, ▲ or ▼ is
displayed in the first column, as shown on
