B. 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. Appendix C,

beginning on page 167 of the

Lassen iQ_Reference Manual_Rev b.pdf

(included on the CDROM of this manual), provides the

information needed to use of the TAIP functions.

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.
