C Trimble ASCII Interface Protocol
(TAIP)
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, seven bit modems and portable computers. Although,
sensors incorporating this protocol are shipped from the factory with a specific serial port
setting, the port characteristics are fully programmable through TAIP messages.
This appendix is designed for easy reference to TAIP message formats and describes all
the TAIP messages defined at the time of printing. Some of the defined TAIP messages
are not supported by the Lassen-SK8 receiver. The Lassen-SK8 supports the following
TAIP messages:
Lassen-SK8 supported TAIP messages include:
AL Altitude/Up Velocity PR Protocol
