Is a wireless cell phone transmitter available for Campbell Scientific dataloggers?
Yes. Both the RavenXTV (Verizon) and the RavenXTG (AT&T) are available.
Do the RavenXTV and the RavenXTG come with a half-wave antenna?
No. A half-wave antenna may not work in the transmission area. Several antenna options, however, are available for purchase:
Do the RavenXTV and the RavenXTG require a dipole cellular antenna?
No. A dipole antenna, such as the 21831, transmits a short distance, emitting a signal 360° around the antenna plain. To transmit to a distant point, a Yagi antenna, such as the 10530, is a more appropriate option.
Do the RavenXTV and the RavenXTG have an RS-232 DB9 connector?
Yes. Both modems connect to a datalogger using an RS-232 9-pin connector for their communication.
Do the RavenXTV and the RavenXTG run on 12 Vdc?
Yes. These modems have an input voltage range of 6 to 28 Vdc.
What configuration settings need to be made to a RavenXTG to make an AT&T network mobile-to-mobile connection?
AT&T’s standard Access Point Names (APN) do not allow mobile-to-mobile connections within their network. However, a mobile device on a non-AT&T network would be able to connect to an AT&T mobile device; for instance, connect with LoggerLink on a Verizon device to a datalogger with a RavenXTG. For more details, contact an application engineer at Campbell Scientific.
Can a RavenXTG be used in an application outside of the U.S.?
Yes. The RavenXTG uses the GPRS/GSM technology, which is commonly used throughout the world. However, be sure to check with the service providers to verify what network technology they use.
Are there any unique cabling requirements to connect a CR800 or CR850 with a Raven XT-series modem?
A standard null modem cable can be used to connect a RavenXT-series modem to the datalogger’s RS-232 port. Alternatively, an SC12 cable and an SC105 interface can be used to connect the RavenXT-series modem to the datalogger’s CS I/O port.
What needs to be done to have a data table sent to an FTP server using a RavenXTV or a RavenXTG?
For the datalogger to transfer data via FTP, the modem has to be set up to use a PPP connection between it and the datalogger.
Is it possible to network two dataloggers to download data from both over a single cell phone using a Raven XT-series modem?
It is not possible to connect two dataloggers to one modem and transmit data from both dataloggers. However, two dataloggers can be networked together so that data is sent from one datalogger to the other, and then the datalogger connected to the modem can transmit the data from both dataloggers.
How can the RavenXTG or RavenXTV be coded to only work for a couple hours when the data is to be sent to the server?
The simplest and most robust way of doing this is to program the datalogger to turn the modem on and off at the user-specified times. See the “Decisions, Decisions, Decisions…” article for more information.
Using the RavenXTG or RavenXTV as an Internet device, is it possible to have the datalogger email the data file to multiple email addresses daily?
Yes. This is done in the datalogger program.
If the RS-232 connection between a datalogger and a Raven XT-series modem works fine, but the CS I/O connection doesn’t work, what might be the cause?
If the connection can no longer be made to a datalogger that is connected to a Raven XT-series modem via an RS-232 port, what might be the reason?
There are three main reasons that a datalogger might lose communication over a cellular modem:
