Campbell Scientific ET107 Evapotranspiration Monitoring Station - Manual (Page 44)

ET107 Weather Station
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,
Communication Modems Schematics.
Default settings for the CR1000 in the ET107 station.
• PakBus address 1
• RS-232 Port: Autobaud (300 – 115,200 Baud)
• ME: Autobaud
• SDC7 or SDC8: 115,200 Baud
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 2-26). 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 ET107 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.
It’s best to use Device Configuration Utility (DevConfig) and
connect directly to the station to change the CR1000
configuration. DevConfig is included with LoggerNet and can be
obtained, at no charge, from our website.
