The DSC1400 includes a list of 9 working chan-
nels which can be scrolled through when using
the Routine or Group Calling options (see sec-

5 Installation
5.1 Fitting the DSC1400
Choose a suitable location that is free from
moisture, excessive heat and vibration, and
which is sufficiently close to the RT1400 radio
for the interconnecting cable to reach.
The DSC1400 has been designed to use the
same mounting accessories as the RT1400 and
so can be desktop, overhead or flush mounted.
The MB1000 standard bracket for desktop and
overhead mounting is supplied with the unit
(Fig 5.1), and the flush mounting bracket
FMB1000 is available as a separate accessory.
Allow at least 15mm (0.6in) clearance behind
the DSC1400 for the cables when choosing a
location. Note that, unlike the RT1400, the
DSC1400 is not waterproof and therefore
should always be fitted in an interior position.
5.2 Electrical Installation
To connect the DSC1400 to the RT1400, simply
unplug the Fistmike/Handset from the front of
the RT1400 and plug in the cable from the back
of the DSC1400, which supplies all data and
power to the DSC1400 from the RT1400. Plug
the Fistmike/Handset into the socket on the
front of the DSC1400 (Fig 5.2).
5.3 Interfacing via NMEA
The DSC1400 incorporates an internal
NMEA0183 processor which is used to provide
position, date and time data from an external
navigator - ideally a GPS.
The DSC1400 can process NMEA0183 version
2.0 sentences
RMC, GGA
and
GLL
, either of
which will provide the necessary data.
NMEA0183 version 1.5 is also compatible, if
ZDA
is provided in addition to
GLL
.
