Programming the A76
Before the A76 can operate, the radio must be configured correctly. The PROGRAM command is used to set
up the default configuration of the A76. An Tait PC application is available for this.
As the serial port of the A76 is expecting NMEA data, the programming command must be in NMEA type
format. For this purpose four new Tait proprietary NMEA messages have been created:
•
PTPGM - for programming the database configuration
•
PTWDB - response from the A76 to a PTPGM message
•
PTRDB - for reading the database configuration
•
PTDAT - response from the A76 to a PTRDB message
The NMEA PROGRAM command has the format :
$PTPGM [ITEM1] , [ITEM2] , [ITEM3] , [ITEM4] , [ITEM5] , [ITEM6] , [ITEM7] , [ITEM8] , [ITEM9] , [ITEM10]
[PARAMETER]
