function with two-place precision. Refer to the manufacturer’s instruc-
tions for how many digits of precision are required for that particular
device.

(PORT 1 / PORT 2 SETUP)

The 941X defaults to a two-second update interval for data transmission.
There are some applications where a longer update period is required,
and the 941X allows you to increase that span to 999 seconds.

(PORT 1 / PORT 2 SETUP)

Many new marine electronic devices (such as radars and electronic plot-
ters) can display your waypoint names, if they are output by the 941X.

If your peripheral equipment has this capability, change the WAYPOINT
ID AS field from NUMBER to NAME, using the EDIT menu key, then
the up/down cursor arrow keys. Press ENTER. The listening device will
now display your six-character waypoint names.

Certain older devices may not accept sentences containing the NMEA
0183 checksum that is output by the 941X. In such cases, the device may
not operate properly, if at all.

If you encounter difficulty when interfacing to older equipment, the 941X
offers you the flexibility of turning off the NMEA 0183 checksum. Move
the cursor to NMEA 0183 CHECKSUMS, press the EDIT menu key,
and use the up or down cursor key to change the setting from ON to
OFF. Press ENTER, then RETURN when you are done.
