Modem Interface
If connecting to RS-232 port:
Null Modem Cable (pn 18663) — connects the modem to the
CR3000, CR800 series, CR2XX, CR300 series, CR1000, or
CR5000
RS-232 port.
CPI/RS-232 RJ45 to DB9 Cable (pn 31055) — connects the
modem to the CR6
CPI/RS-232 port.

The SC105 must be configured for use with the modem using
DevConfig . Settings should be:
CS I/O Mode: SDC Address 7, 8, 10, or 11
RS-232 Mode: Modem
Baud Rate: 115.2K or 9600 baud depending on datalogger model
8 data bits, 1 stop bit, no parity
If connecting to Ethernet port:
Ethernet Cable (pn 28899) — connects the modem to the CR6 or
NLxxx.
•
RV50 Mounting Kit (pn 32252) — includes mounting hardware for
securing the modem to below-referenced environmental enclosure.

Antenna — the following antennas are available from Campbell Scientific
(see FIGURE
7-1 ). Contact a Campbell Scientific application engineer for
help in determining the best antenna for your application.
o
The 20679 is a dual-band, omnidirectional antenna for our CDMA
and GPRS/EDGE digital-cellular modems. It covers both the 800-
MHz band and the 1.9-GHz band. For the 800-MHz band, the 20679
provides a 0-dBd gain. For the 1.9-GHz band, the 20679 provides a 3-
dBd gain. This antenna is recommended for locations where cellular
coverage is strong.
The 20679 includes a mount/U-bolt assembly that allows the antenna
to be mounted to a mast, crossarm, or user-supplied pole (outer
diameter of up to 3.8 cm (1.5 in)).
o
The 32262 is an omnidirectional antenna with mounting bracket that
is ideally suited for use with 4G and 3G cellular gateways. The
