Hardware operation condition confirmation
CNU Normal operation condition confirmation
1) Check CNU LED1 is continuously blinking : 485 communication LED
2) Check L06D, L07D LEDs are Lighting : LAN CABLE connection confirmation LED
3) Check L09D,L08D blinking : LAN communication condition confirmation LED
L08D blinking : connected Deluxe central controller(10M BPS)
L09D blinking : connected PC(100M BPS)
Notice : If the LAN cable is are not connected between PC(or DCC) and CNU then the LED6D,7D are not light
LAN communication condition confirmation
1) After connecting the LAN CABLE, executing, DOS Command of the PC which is connected
2) PING test : type 'ping' and 'CNU IP' then Enter key
ex) PING 192.168.1.101 (The CNU IP will be different which is real set ,so type real CNU IP)
Notice : The response time will be different to system condition
If ping test is fail(request tine out) then check below condition
- CNU IP is correct?
- PC Network information has same with the CNU IP information
ex) If CNU IP is 192.168.1.101 then the PC network information does to have a same network
information 192.168.1.XXX(except same CNU IP number or 1 )
3) When PING test executes well, LAN communication operates in the normality.
485 Communication condition confirmation
1) Before confirm 485 communication condition, check indoor address setting and 485 G/W operation LED's condition
and power resource condition.
2) Connecting RS232 cable and running RS232 monitoring program
3) In order to appear information in monitoring program window, Setup Com port and Baud rate to 57600.
4) The data will come up and it will be able to confirm a number of indoor
Setup address of indoor appears, 485 communication
operational condition of CNU is normality
ex) number monitoring of connected indoor
Notice : The indoor number searching time could be delayed in in
the condition which searches
When neither information of the indoor information is searched
Check below check points
1) Check Indoor unit address are set correct or not
2) Check the 485 gateway setting (s/w setting, connect
