2.3 Power Considerations
•
A power cable included with the modem connects to the datalogger's 12 V
or switched 12 V terminal. Connection to the switched 12 V terminal
allows the datalogger to switch power to the modem during scheduled
transmission intervals if desired.
•
When using the switched 12 V terminal, the modem can be powered with
a BP12 battery, CH100 charger/regulator, and MSX10 solar panel.
3. Configuration
3.1 Establish Cellular Service
Prior to contacting Alltel, have the following information on hand:
1.
Electronic Serial Number (ESN). The ESN is found on the unit label.
2.
Desired area code and local prefix. Normally, choose the same area code
and prefix as the calling PC. These will ensure that calls are billed at local
rates, even if the phone is used outside the local calling area.
Contact the provider, tell the account representative that you would like to
open an account for a new voice phone. Request a voice plan and ask that
voice mail NOT be activated. The Redwing may show up on Alltel’s network
as a MultiTech device; this is okay.
The provider will provide you with the following:
1.
MDN (Mobile Directory Number). This is the number you dial.
2.
MIN (Mobile Identification Number). This number identifies the Redwing
on the cellular network. This may be the same number as the MDN.
3.2 Program the Modem
Program the modem with CellWizard.exe, available from Campbell Scientific,
Inc. The appendix describes how to program the modem via a terminal
emulator; however, programming via a terminal emulator is NOT the preferred
method.
1.
Connect the phone to your computer COM port.
2.
Apply 12 volts to the phone. Red lead to +, black lead to -.
3.
Start CellWizard.exe and select the COM port you will be using to
program the Redwing.
4.
Select desired datalogger baud rate. For the CR1000 or CR5000
dataloggers, set the baud rate to 115200. For the CR10(X), CR510, CR7,
21X, or CR200 dataloggers, set the baud rate to 9600. For the CR23X
datalogger, set the baud rate to 38400.
