devices
Connecting with a Yeoman chart plotter
To enable the 951/952 to communicate with a Yeoman electronic chart
plotter, refer to the table below.
Connecting with a radar device
The 951/952 can be set to interface with a radar device. The unit supports
the NMEA TLL sentence, sometimes referred to as the “rattle” sentence.
This sentence lets the unit communicate its position to an interfaced
radar device, which tracks a user-defined target. In turn, the interfaced
radar device communicates to the unit the target’s position—in lat/lon
coordinates—so that you can see the target symbol, displayed as a way-
point, right on the CHART screen (after you save the position). The target
symbol is displayed with the name -RADAR on the CHART screen, as well
as on both the ALPHA and LOCAL waypoints lists (to access these lists,
press the
key, then menu key, then the
menu key until you reach the desired list). On the ALPHA and
LOCAL lists, this radar waypoint is displayed with the hours/minutes/sec-
onds/day/month/year (for example, 12:50:20-30JUN99) in the descrip-
tion field.
Setting the anchor-watch alarm honk
In the anchor-watch alarm function, you can set the 951/952 to honk, in
addition to beep, as long as you’ve connected a honker with pin #14 on
the interface connector. See Figure 23 below for the hardware modifica-
tion required to support the unit’s honk feature. You can use Radio Shack
part number 273-060, or an equivalent.
