→Garmin and the RTCM
The VOTER is designed to accept both 3.3V or 5V signals, and ''should'' work fine.

* Some of the Garmin GPS's come with 4800 baud set as default. If you are getting a "Warning: GPS Data time period elapsed" error on your RTCM, change both the GPS and RTCM to use 9600 baud. To do this, interface the GPS to a DB9 connector as per page 8 of the [http://wiki.allstarlink.org/w/images/4/41/GPS_18x_Tech_Specs.pdf manual] (remembering to ONLY use 5V as the power source *facepalm*). Once done, download, extract and open [http://www8.garmin.com/support/download_details.jsp?id=4053 SNSRXCFG_330.exe] and run.
# Select your GPS (in most cases GPS 18x PC/LVC). Press F10 to switch to NMEA mode (Config > Switch to NMEA Mode)
# Select Config > Setup and choose the COM port your GPS is connected too. Leave baud rate as auto for now, OK.
# Select Comm > Connect to connect to the GPS.
# Go to Config > Get Configuration from GPS to download it's current configuration
# Click File > Save to save the current configuration
# In Config > Sensor Configuration change the Baud Rate to 9600. You can also check to make sure 1PPS is enabled here too. Click OK.
# Hitting F7 when in the main window of the software also brings up the GPS sentences to output if that is of interest.
# File > Save to a different file than step 5.
# Press F9 or Config > Send Configuration to GPS. This will then send all the changes you made to the GPS unit (including baud rate so a reconnect may be needed)
