2.4.11 Sensor Verification and Clock Set
1.
Send the weather station program to the station using your Campbell
Scientific software such as VisualWeather, PC400, or LoggerNet. Verify
all sensors are functioning correctly. Verify the weather station clock and
set as necessary.
The ET107 comes with a default program (see Appendix D).
NOTE
Use standard time in the station if calculating evapotranspiration
(ETsz). Do not use daylight savings time.
NOTE
2.
Additional Station Communication Options:
a)
The station can be accessed directly using a CR1000KD keypad
display at the weather station. Plug the keypad into the extra plug
coming off the 9-pin connector marked “CS I/O”.
b)
A laptop can be used to connect directly to the RS-232 port at the
station using a standard 9-pin serial cable. Do NOT use a null modem
cable.
c)
The station can be connected directly to using a Palm with CSI
PConnect software and connector/cable or PConnect CE if using a
Windows CE based handheld with connector/cable.
2.5 Communication Peripherals
Only one communication kit can be mounted inside the ET enclosure.
Communication kits ordered with the ET Enclosure are pre-mounted and pre-
wired; no further connections inside the enclosure are necessary. Follow the
"External Installation" procedures in later sections to make the external
connections.
If you received a telecommunication kit separate from the ET Enclosure,
follow the "Internal Installation" procedures outlined in later sections.
Schematics for the phone and short haul modems are in Section 4.3.3.

2.5.1 Direct Connect to ET107 Station
The ET107 station does not require an interface device for direct RS-232
communication. The inside of the enclosure has a RS-232 and CS I/O port
available for communication (see Figure 2.5-1). Most standard communication
options use the CS I/O port leaving the RS-232 port free for direct
communication with a laptop or desktop computer using a standard RS-232
