Instruction manual

LS300G GSM/GPRS/EDGE/HSPA+ Sierra Wireless Cellular Modem
• Modem Interface
If connecting to RS-232 port:
Null Modem Cable (pn 18663) — connects the modem to the
CR23X, CR3000, CR800, CR2XX, CR1000, or CR5000 RS-232
port.
If connecting to CS I/O port:
SC105 or SC932A Interface — connects the modem to the 21X,
CR510, CR10(X), CR7, or any current datalogger with a CS I/O
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
• LS300 Mounting Kit (pn 30988) — includes mounting hardware for
securing the modem to below-referenced environmental enclosure and a 9-
pin male to 9-pin female cable.
• Antenna — the following antennas are available from Campbell Scientific.
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 18285 is a 1 dBd omnidirectional antenna. This antenna is dual
band, covering both the 800 MHz and 1.9 GHz bands, and is strongly
recommended where cellular coverage is strong. The 18285 includes
a mount/U-bolt assembly for attaching the antenna to a mast, post, or
crossarm up to 3.8 cm (1.5 in) in diameter.
o The 31128 8 dBd Yagi Antenna is a higher gain antenna that should
be “aimed” at the service provider’s antenna. It covers both the 800-
MHz band and the 1.9-GHz band. The 31128 comes with bracket/
U-bolt assembly for attaching the antenna to a mast or post. This
antenna is recommended for fringe areas that require a higher gain
antenna.
