A Trimble Standard Interface Protocol
The Trimble Standard Interface Protocol (TSIP) provides commands
that the system designer can use to configure a GPS receiver for
optimum performance in a variety of applications. TSIP enables the
system designer to customize the configuration of a GPS module to
meet the requirements of a specific application.
TSIP is a simple bidirectional, binary packet protocol used in a wide
variety of Trimble GPS receivers. TSIP offers a broad range of
command packets and report packets that provide the GPS user with
maximum control over the Acutime 2000 and ACE UTC receivers.
This appendix provides the information needed to make use of the
powerful TSIP features, enhance overall system performance, and
reduce the total development time. The reference tables beginning on
page A-7 help you determine which packets apply to your
application. For those applications requiring customization, see
TableA-12 for a detailed description of the key setup parameters.
Application guidelines are provided for each TSIP command packet,
beginning on page A-10.

A.1 Interface Scope

The Trimble Standard Interface Protocol (TSIP) is based on the
transmission of packets of information between the user equipment
(host) and the GPS receiver. Each packet includes an identification
code (1 byte, representing 2 hexadecimal digits) that identifies the
