[B] Error messages that are not displayed in the
Last Error Message
1 Error messages that can be displayed on the FL or
LCD
1) Communication Error between the Front
Microprocessor and EEPROM
If no response is detected between the Front Microprocessor
and EEPROM within a regulated timeframe, the display
will show the following message.
Ensure that IIC communications have been established
between R235 and R236 on CUP12190x when the unit
is powered on or put into STANDBY.
If no communication is detected, check the soldering of
R212, R213, R235, R236, IC21 and IC22.
IF the error cannot be corrected through normal
operations, IC22 may be broke. If such is the case,
replace IC22.
2) Error Messages special to USB
If no response is made while the unit is communicating
with the USB Module, the display will show the following
message.
If the indication will not be changed to "USB_Com_Err",
the communication may be unstable. Check if the
regulated voltage is applied to each of L161, L251 and
L252 on CUP12190x.
Check if 1pin and 50pin in IC11 on CUP12190x receive
the clock signal of the designated frequency
Check the soldering points of IC21, IC11and around.
Refer to the communication between the USB module and
the microprocessor on the communication waveform
page and check the signal. If the message below cannot
be cleared while the unit is functioning normally, IC11 may
be broken. If that is the case, replace IC11.
When the unit is connected with an incompatible UBS
device or a device configured with an incompatible
communication protocol or command, the display will
show the following message.
If this message is displayed, the device is incompatible
and cannot be connected to the unit.
If the information obtained from the USB has a aw or
improper data, which are detected by the USB host
controller in the unit, the display will show the following
message.
