[. . . ] To use 25 & 50 bps, you will need to manually tune the beacon via the GPS receiver or other source. For non-GARMIN receivers which do not supply a valid tuning interface (pg. 11-12) to the GBR 23, it is not necessary to connect to the DATA IN (BROWN) wire of the GBR 23. The GBR 23 should tune into a DGPS station within about 10 minutes. The unit will store the last used frequency in non-volatile memory and default to that frequency on next use. If you lose DGPS signal, the unit will attempt to reconnect to the last frequency and if necessary, tune to another station.

To remotely switch power to the GBR 23, see Figure 2. 10 Figure 3 (cont. ): Sample Wiring to GARMIN GPS Units Operation Using the GBR 23 When using the GBR 23, tuning may be either done automatically or controlled by the GPS unit. Your GARMIN GPS unit provides a Beacon Receiver Setup Page and, in some cases, Beacon Log Page for this purpose. The operating instructions provided below are generalized to cover several different GARMIN models and may not exactly match your display. For additional information on operating your GPS unit with the GBR 23, refer to the owner's manual for your GPS unit. Screen examples from various model GARMIN units are provided on the following pages. 1. From the Interface Setup Page, select an RTCM input. If a baud rate selection is also provided, specify 4800. On GARMIN GPS units, RTCM input/NMEA 0183 output should be selected. If additional devices, such as an autopilot or plotter, are connected to the GPS unit, they must be set to work with NMEA 0183 as well. On some newer model GARMIN GPS receivers, you may set the interface to "Garmin Bcn Rcvr". This is a scan option, seperate from the GBR 23 scan, which will automatically scan for a DGPS frequency and bit rate. Please refer to your GPS owner's manual for using this function. If this setting is used, you may skip step 4. From the Interface Setup Page, enter the "Tuned To:" frequency and the "Bit Rate" for the nearest DGPS beacon transmitter. (Refer to the Beacon Reference Card for this information. ) 5. [. . . ] 4) "RTCM Input Failed" displayed on GPS unit Intermittent connection between GBR 23 and GPS unit. Interference from ship's electrical system, other electronic items, thunderstorm activity, or another source is preventing signal lock-on. Also refer to Troubleshooting problems 5 and 6. Wrong frequency or bit rate selected on GPS unit. [. . . ]
