Redwing Digital Cellular Modem

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 Redwing when upgrading from analog cellular to CDPD.

An RF adapter connector is required to connect the TNC female connector

on the Redwing to the mini UHF male connector on the 10530 cable (e.g.,

Radio Shack Part No. 278-148).

• Power Supply.

• Environmental Enclosure—typically an ENC 12/14 or ENC 16/18.

5.2 Power Considerations

The communication connection between the Redwing 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 Redwing Serial Port via SC932:

CS I/O >> SC12 Cable >> SC932 >> 10871 >> SC12 >> Serial Port

Datalogger CS I/O connection to Redwing Serial Port via SC932A:

CS I/O >> SC12 Cable >> SC932A SC12 >> Serial Port

CR23X or CR5000 RS-232 to Redwing 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.
