Garmin GMA 347 Installation Manual page 55

If the user presses the Disconnect button after an initial connection is made with the GMA 347, the
Connect button will replace the Disconnect button. After the Connect button is pressed the application
will behave similarly to initial startup in that it will continuously try to connect to a GMA 347 on COM
ports 1 – 10 until successful.
If a GMA 347 is connected to the PC COM port, the Disconnect button will be visible above the Apply
button. Pressing the Disconnect button causes the GMA 347 Configuration Tool to disconnect from the
GMA 347 and the Connect button will have to be pressed to reconnect.
If there is a connection between the PC and the GMA 347 and the connection gets
interrupted for more than five seconds (either by loss of power to the GMA 347 or a
disconnected data cable), the effect will be identical to pressing the Disconnect button.
5.5.1 Save and Exit Buttons
The Save and Exit button will apply the SET settings and will close the Configuration Tool.
5.5.2 Cancel Button
The Cancel button will NOT apply the SET settings and will close the Configuration Tool.
5.5.3 Apply Button
The Apply button will apply the SET settings and the Configuration Tool will remain open.
5.5.4 Upload Button
The Upload button is used to perform a system or boot block code upload.
5.5.5 Load Config and Save Config Buttons
The Load Config option will load settings from a configuration file into the GMA 347. The data format
of the config file is shown in the CONFIG EXAMPLE at the end of this document. The config file
format should never be changed, only the values that follow the equals (=) signs.
If values entered are not valid as specified in the VALID DATA RANGES section at the end of this
document, the incorrect value will be replaced with a default value.
For options that have a data range of –31 to 31 the Load Config operation will accept a two digit number
with or without a negative sign (Ex.... -15, 15). If characters are entered after a number (i.e. 8c), the 8
will be the only value output to the application's window. If only characters are entered, a zero (0) will
be output to the display for that value.
For options that use a 0 or 1 for the config, a 0 represents NOT SET, and a 1 represents that the option
will be SET.
The Save Config button queries the GMA 347 for the current config values, then stores those values in a
".ini" file regardless of whether or not the SET box is different than the ACTIVE box. The default file
type is ".ini". When saving the config file leave the file type as ".ini". This will make it easier when
loading the Config using the Load Config button (since the file type is defaulted to ".ini").
