How does the Artex Programming Dongle (DGL-1) function?
Most commonly utilized by fleet operators, the DGL-1 programming dongle allows an ELT to be transferred between aircraft without having to reprogram or re-register. The Artex DGL-1 is mounted on the ELT cover (see picture). The DGL-1 is not a memory device that stores multiple ELT coding formats. Instead, the aircraft 24 bit address is coded into the dongle by setting a series of small dip switches. The switches are accessed by removing 4 screws that attach the dongle to the ELT top cover. Inside the dongle, there are two rows of 12 switches (see picture). These 24 switches are used to set the aircraft’s 24 bit address by way of binary 1s and 0s. 1s are electrical ground, 0s are electrically open. A few other notes regarding the DGL-1: • The connector between the DGL-1 and ELT is only compatible with the C406 and G406 series ELTs. • The DGL-1 switches do not have to be set by an approved Artex programming facility. • The 24 bit address programmed via the DGL-1 switches overwrites any o
