Trimble ThunderBolt E GPS Disciplined Clock User Guide     

Setting up and Running the ThunderBolt E     

8.

The ThunderBolt E automatically begins its self-survey. When this is complete 
and the receiver achieves a position fix, the following information appears in the 
software:

–

position

–

time

–

satellites tracked

–

GPS receiver status

If the Trimble GPS Monitor program displays a question mark (?) in a data field, the 
receiver has not reported a status for this field. If the question mark stays in place, the 
GPS module may not be communicating with the computer. Check the interface cable 
connections and verify that the serial port selection and settings are set to 9600 baud, 
no parity, 8-bit, and 1 stop/start bit.

If the communication fails, call the Trimble Technical Assistance Center (TAC) at 
1 (800) 767-4822.

Packet 0xBC sets the ThunderBolt E GPS port characteristics. To change the receiver 
port and then set or request the Input/Output baud rate, data bits, parity, stop bits, and 
flow control parameters, select Configure / Receiver Configuration / Port Configuration 
dialog.

The Trimble Standard Interface Protocol (TSIP) consists of command packets and 
report packets. The basic features that are described here include some of the more 
commonly used commands and reports. For a complete description of TSIP, see 

Packet 0x8E-4A enables you to delay or advance the 1 PPS. This may be required to 
compensate for a long cable run. Negative values advance the 1 PPS and compensate 
for cable delay. The 10 MHz and 1 PPS output will remain synchronized.
