Q&A about TR-71W / 72W
Q.1 The TR-7W loggers use an AC adaptor, what happens when there is power
shortage ?
A
During a power shortage the Web Server will not function and communication via LAN
cannot occur, but with the backup battery, data measurement and recording will continue.
The backup battery life is about 3 months. If the battery loses all of its power, the recorded
data will also be lost, so please be careful.
- For info about what a web server is, see [Q&A about Web Server Functions].
Q.2
Can I connect directly to my computer with the LAN cable that comes with
the logger ?
A
The LAN cable supplied is a straight LAN cable and in some cases it cannot be used to
connect directly to your computer. Therefore, we suggest using a cross LAN cable in order
to connect an TR-7W directly to your computer. Please purchase a cross LAN cable at your
local computer supply store.
Q.3 Does the TR-7W have a clock and calendar ?
A
The TR-7W has an internal clock (calendar) built into it.
If the internal clock’s date and time are set incorrectly, the programmed recording start
time, the download data time, and the monitor current readings time will all be wrong. Make
sure to set correctly before using.
NOTE:
- If you make clock settings manually, the clock will lose its settings upon removal of the AC
adaptor or after restarting the system.
Q.4
If two TR-7W are connected to the same router, how can I identify which is
which ?
A
If two or more TR-7W loggers are connected to the same router, it is possible to identify by
setting each with am individual IP address and from the Internet side can be identified by
the port number to which it is connected.
See Q.7 in "Q&A about the Internet" for more details.
Q.5 Where can I set the port number ?
A
The port number can be set in the TR-7W " TR-7W Settings Utility".
Under normal conditions, for HTTP communication the setting is 80, but if you wish to
synchronize the settings to match the router settings, it is necessary to change the settings
for the TR-7W and for the router.
