Programming
The data modem is pc programmable. The parameters available for programming
include:
Frequency, channel spacing and sub-audible tones on a per channel basis
Radio settings such as power save mode,TX lockout, TX timeout, Squelch
Module options when A FSK, FFSK or GMSK module is
fi
tted, such as setting baud
rate, dumb or auto mode, Hyper Terminal mode and data settings (
fl
ow control,
block size etc)
The pc program also allows for squelch adjustments and calibration Refer to
programming manual and PC software.
Installation
Antennas
It is important that any antennas are installed in a suitable location with an adequate
ground plane. Ideally, multiple antennas should be separated by a minimum of a
wavelength (at the lowest frequency), whilst still retaining a good ground plane for each
antenna. Therefore, for a 400MHz system, the ideal separation should be a minimum of
0.75m (~30in), and for 150MHz system the minimum should be 2.5m (~98in).
Warning: If installing an antenna near people it is necessary to ensure the minimum
separation is maintained. This particularly important where prolonged exposure is likely.
For a full range of antenna options and other accessories visit the Mobile Expertise
Global web site.
Power sources
It is important that a “clean” source of power is used for the supply to the modem
Fuse replacement
We recommend an inline “quick blow” fuse rating of 4 amps be
fi
tted to the +ve supply.
Cabling
If possible, run RF cables separately from other cables and keep RF cables apart from
one another to avoid interference / coupling.
When
fi
tting the modem into a
fi
xed installation care must be taken in the routing of all
cabling such that the insulation cannot become damaged.
Fixing
We recommend that the TS-D200/me-D350 is securely
fi
xed to a surface, either directly,
or with a suitable bracket. The
fi
xing hole centre dimensions are as shown.
The modem can be attached to any surface by using suitable size screws through the
M3.5 holes in the mounting
fl
anges.
N.B.
Mounting hole positions are different on each side.
