PV WEB DATA LOGGER
TK-E20-01/08/16/08S/16S/32D Instruction
1. General
TAOKE web data logger of PV plants collects the operation data,
including inverter, radiation, meter data, etc. by RS-485/422, and
sends these data to website via ethernet so that user can check
the power station running status by logging on to internet website.

PV web data logger should be installed where dry and ventilation
are required in-door. It can be installed by desktop or
wall-mounting.
Connection the logger via “RS485/422” socket to the PV devices,
including inverter, meter, sensor (radiation, temperature etc.) etc.,
and wiring among each other with CAT5 cable.

The logger is set to identify network via DHCP automatically.
Connection the logger via “LAN” socket to a network router with
network cable, the LED-ETHERNET flashes quickly. When the
LED is steady on, the IP address is allocated. If the LED flashes
slowly after one minute, the IP address is not allocated
automatically. You can set a fix IP address via computer. Read the
“Logger set tool User Manual” and use the “Logger set tool.exe” in
the disk.
If you want to reset “IP address allocated via DHCP
automatically”, pull out the DC plug, press the reset key and
plug in at the same time. The 4 LEDs on top are flashing. When all
the LEDs are steady on, release the key.
NOTE:Each logger connected to a network has got its own IP

address. This address can not be used twice and can not be
allocated to another logger, computer, etc. appliance. When the
‘ETHERNET’ indicator is steady on, but there is no data on website
or you can not search the logger via computer with “Logger set
tool.exe”. If the logger is set a fix IP address, you have set a
wrong IP address or the IP address is allocated twice. If the logger
is allocated IP address via DHCP automatically, the IP address is
allocated twice.

Reconnecting power after
checking the circuit.
Replace power adaptor.
Check cable among the logger
and PV devices.
Check PV device.
Contact installing personnel.
Check the “LAN” socket, if the
two LEDs are not blinking,
check if the cable get loose.
If the LEDs of “LAN” socket
are blinking, the IP address is
set wrong, or this address is
allocated twice.
