Trimble ThunderBolt E GPS Disciplined Clock User Guide     

Trimble Standard Interface Protocol     

Thunderbolt E provides a number of user-configurable parameters that enables the 
user to customize its operation. These parameters are stored in NVS memory to be 
retained during loss of power and through resets. At reset or power up, ThunderBolt E 
configures itself based on the parameters stored in NVS. The user can change the 
values of these parameters to achieve the desired operation using a variety of TSIP 
packets. ThunderBolt E configures itself based upon the new parameters immediately, 
but the new parameter is not automatically saved to NVS. The user must direct 
ThunderBolt E to save the parameters to NVS. This is done by sending packet 0x8E-4C 
with the ID of the segment containing the changed parameter. Users can also direct 
ThunderBolt E to set the parameter values for a specified segment to their factory 
defaults by sending packet 0x8E-45.

To customize ThunderBolt E output: 

1.

Set up ThunderBolt E using TSIP commands until the required operation is 
achieved.

2.

Use command 0x8E-4C to store the settings in non-volatile memory (except for 
position, which is saved or deleted with packet 0x8E-A6.)

These settings will control ThunderBolt E operations whenever it is cold-reset or 
power cycled. The following tables illustrate how the user configurable data is 
mapped.
