5.5.1 Modem Connection using the L18663 Null Modem Cable
In order to connect to a CR1000, CR3000, CR800, or CR200X series RS-232
port you will require a Null Modem Cable, Campbell Scientific part number
L18663. Connect one end of the Null Modem Cable to the IPn3Gb Cellular
Modem and the other to the datalogger’s RS-232 port.
5.5.2 Modem Connection using the SC932A
If connecting to any datalogger’s CS I/O port you will require an SC932A
interface from Campbell Scientific. Connect the supplied black SC12 cable to
the datalogger side of the SC932A interface, and then to the CS I/O port of the
datalogger. Connect the DCE Device side of the SC932A interface to the
IPn3Gb Cellular Modem’s RS-232 port using the supplied straight through
serial cable L10873.

5.5.3 Modem Connection using Ethernet
In some cases it may be desirable to connect using the Ethernet interface
available on the IPn3Gb Cellular Modem. To do this, you will require a
CR1000 or CR3000 with either a NL120 Ethernet Interface, NL115
Ethernet/Compact Flash Module, or any datalogger using a NL2XX series
device. A crossover Ethernet cable is needed to connect the two devices.
Please review the literature for the specific interface for more details.
5.6 Test the Cellular Connection
After the Device Map has been configured, it is recommended to test the
cellular connection using the “Connect” screen, as shown below. Click on the
appropriate station, then click the “Connect” button to initiate a call to the
datalogger. Be sure all connections are complete and power is supplied to both
the modem and datalogger.
If the call is successful, the connectors at the bottom of the screen will come
together, and time information from the datalogger will be displayed the
“Station Date/Time” field. If the connection fails, a “Communications Failure”
message is displayed. Troubleshooting procedures can be found in
Section 7
