RayChart 620
The RayChart is waterproof and provided with a sun cover. It is
designed for above or below deck installation, where it is:
• Easily read by the helmsman
• Protected against physical damage
• At least 230mm (9in) from a compass
• At least 1m (3ft) from radio receiving equipment
• Accessible from behind for ease of installation and cable running
Although the RayChart is designed to meet the CFR46 waterproofing
standard, it is advisable to mount it, whenever possible, so that it is not
exposed to the direct effects of salt spray or the hot sun.
Note: LCD displays have a specific viewing angle for optimum visibility,
which is normally within 30° of head-on viewing. You may wish to apply
power to the RayChart and view the display in various locations before
mounting the unit permanently.
Connection Options
The RayChart 620 can be configured to operate in one of three different
operating modes:
• SeaTalk, using the dedicated SeaTalk input/output ports.
Navigation data can be received from the dedicated GPS port or
from the SeaTalk port. If data is available on both, then data from the
SeaTalk port will have priority.
All SeaTalk sentences are decoded, and can be selected for display
via data windows (see Section 6.3). All SeaTalk data is available as
output.
• GPS, using the GPS port as the only source of navigational data.
You should only select this option if you are connecting a RayStar
112 GPS and also require NMEA output. In this mode there is no
SeaTalk interface: use SeaTalk mode if you wish to use the SeaTalk
and GPS ports together.
• NMEA, using the NMEA port as the only source of input data. The
position fixer is normally connected via the NMEA port,
not
via the
GPS port. In this mode there is no SeaTalk interface
The data input and output in each mode is detailed in the following
table. If data from two sources is available, the source marked
“Priority 1” is used.
