Raven II Digital Cellular Modem
6
14453 2 dB ½ Wave Dipole Whip Cellular Antenna
14454 8 dB Yagi Cellular Antenna with 10' Cable
The 10530 antenna sold with the COM100 analog cellular phone can also
be used with the Raven II when upgrading from analog cellular to CDPD.
An RF adapter connector is required to connect the TNC female connector
on the Raven II to the mini UHF male connector on the 10530 cable (e.g.,
Radio Shack Part No. 278-148).

5.2 Power Considerations
The communication connection between the Raven II serial port and the CS
I/O port on the datalogger (or RS-232 on CR23X or CR5000) is made with the
following interfaces:
Datalogger CS I/O connection to Raven II Serial Port via SC932:
CS I/O >> SC12 Cable >> SC932 >> 10871 >> SC12 >> Serial Port
Datalogger CS I/O connection to Raven II Serial Port via SC932A:
CS I/O >> SC12 Cable >> SC932A SC12 >> Serial Port
CR23X or CR5000 RS-232 to Raven II Serial Port Via Null Modem
Dataloggger RS-232 >> 14392 Null Modem Cable >> Serial Port
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, thereby conserving power.
