used when connecting your NavTalk to external NMEA
devices, a DGPS beacon receiver, a personal computer,
etc. Five format settings are available:
GARMIN - the proprietary format used to
exchange waypoint, route, track log
data with a PC or another NavTalk unit.
NMEA - supports the input/output of standard
NMEA 0183 version 2.0 data.
None - Provides no interfacing capabilities.
RTCM/NEMA - allows Differential GPS (DGPS)
input using a standard RTCM-
104 format and also provides
NMEA 0183 version 2.0 output.
RCTM In - allows DGPS input using a standard
RCTM-104 format without any output
capabilities.
RTCM Text - allows DGPS input using a standard
RTCM format, without any output
capabilities
Text Out - allows DGPS output using a standard
RTCM format, without any input
capabilities
To select an input/output format:
1. Highlight the Format field and press ENTER.
2. Select the desired setting using the arrow keypad and press
ENTER.
3. If the GARMIN format is selected, highlight the Transfer
Mode field and press ENTER. Select the desired setting
and press ENTER. The Transfer Mode field allows you to
specify what information to request or send to a second
NavTalk. The Host setting lets you control all data transfer
functions from the second NavTalk or from a PC.
4. If an RTCM format is selected, additional fields are pro-
vided to control a GARMIN GBR 21 beacon receiver
directly from your NavTalk. You can enter the beacon fre-
quency and bit rate on the NavTalk and the information will
be used to tune the beacon receiver. For more information,
refer to owners manual for the GBR 21.
