Use the Auto connect in the File Port menu to establish communication with the SSII. It will search through all of the baud rate in Binary mode then NMEA mode. Use the Protocol Dialog Button to connect to the unit in Binary 9600. Click on Tool Setting | Set Receiver Configuration. In the window that appears, set the navigation rate to 5 HZ and click okay. Use the protocol dialog button to change the unit to NMEA 19200. The SSII 5Hz model can output binary and NMEA at both 1 and 5 Hz. However, the NMEA messages that can be output at 5Hz are the GGA, GLL, GSA, RMC, VTG and 906. Click on Tool Setting | Set default messages list to open the NMEA output configuration window Enter "0" first to clear the setting for each NMEA message that you would like to re-configure then check each NMEA message accordingly. Checkmark the corresponding NMEA messages that you need outputted. You can change the rate by clicking on the rate twice slowly. The NMEA messages that can be output at 5Hz are the GGA, GLL, GSA, RMC, VTG, and 906. You must also have the 5Hz model loaded on your receiver. Message 45, the HW SW Part number, will indicate this with Config #1 saying 169-613955-204 or 169-316955-211 (Non SBAS). For 5Hz output, enter "999" in the rate box. For once every 5 seconds, enter 5 in the rate box. Check "Update NVM List" and click send. Power cycle the receiver. Open "NMEA Output Configuration" window again, then enter "999" for 5 Hz and "1" for 1 Hz, then check the NMEA message. Check "Update NVM List" and click send. Power cycle the receiver and the NMEA message(s) will be output at either 5 Hz or 1 Hz whichever you have chosen.
