Protocol Overview
Trimble ASCII Interface Protocol (TAIP) is a Trimble-specified digital 
communication interface based on printable ASCII characters over a serial data link. 
TAIP was designed specifically for vehicle tracking applications but has become 
common in a number of other applications because of its ease of use. TAIP supports 
both scheduled and polled responses.
TAIP messages may be scheduled for output at a user specified rate starting on a 
given epoch from top of the hour. For communication robustness, the protocol 
optionally supports checksums on all messages. It also provides the user with the 
option of tagging all messages with the unit's user specified identification number 
(ID). This greatly enhances the functional capability of the unit in a network 
environment. Additionally, given the printable ASCII format of all communication, 
TAIP is ideal for use with mobile data terminals, modems, and portable computers. 
Although, receivers incorporating this protocol are shipped from the factory with a 
specific serial port setting, the port characteristics are fully programmable through 
TAIP messages.
The Copernicus GPS Receiver supports the following TAIP messages.
