T107 Weather Station

2.4.9 Sensor Verification and Clock Set

The T107 comes with a default program (see Appendix D).

Use standard time in the station if calculating evapotranspiration

(ETsz). Do not use daylight savings time.

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 Campbell

Scientific 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,

Communication Modems Schematics.

Default settings for the CR1000 in the T107 station.

2.5.1 Direct Connect to T107 Station

The T107 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 2-23). 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 serial cable. The CR1000 datalogger used in the T107 station can speak

with more than one device at a time allowing troubleshooting to be done in the

field with a laptop while remote communication devices are accessing the

station.
