NETWORK CONVERTOR (UTR-YSSA) TROUBLESHOOTING
Circuit board
error 1
1. Error occurence condition
The signal synchronization
between the network devices
is not normally performed.
2. Relevant operation
Error code is displayed.
All control items are not
available.
3. Clearance 
Error is cleared when the
signal synchronization
between the network devices
is normally performed.
2. Network convertor printed
circuit board is faulty.
1. After the SW104 button of network
convertor PCB is pressed for more
than five seconds, or the power of
network convertor is reset.
1) If error dosen't occur, printed circuit
board is normal. Please remove
noise sources near network convertor.
2) If error occurs again, remove noise
sources and take measure with
the following countermeasure.
1. Error occurence condition
Error occurs when the
memorized information in
EEPROM is faulty or
when the intial setting of
network convertor is not
performed correctly.
2. Relevant operation
Error code is displayed.
Other control methods
are still possible.
3. Clearance 
Error is cleared when the
network convertor becomes
operable again.
2. Network convertor printed
circuit board is faulty.
1.
1) If error doesn't occur,printed circuit
board is normal. Please remove
noise sources near network convertor.
2) If error occurs again, remove noise
sources and take measure with
the following countermeasure.
1. Error occurrence condition
Transmission between
standard wired remote
controller and network
convertor is not performed
normally.
2. Relevant operation
1) Error code are displayed.
Control from and display on
the standard wired remote
controller cannot be
performed.
Other control methods
are still possible.
3. Clearance 
Transmission between
standard wired remote
controller and network
convertor is performed
normally.

1) If error doesn't occur,printed circuit
board is normal. Please remove
noise sources near network convertor.
2) If error occurs again, remove noise
sources and take measure with
the following countermeasure.
2. Check the remote controller line to
find whether it has been disconnected,
connected faultily and has a wrong
wiring or not.
3. Check the setting of DIP-SW 107[2]
of network convertor.
5. Check the setting of DIP-SW 1-1 and
DIP-SW 1-4 of standard remote
controllers.
6. Replace standard wired remote
controller printed circuit board or
network convertor printed circuit
