Lassen-SK8 Embedded GPS Module 1-3
Starter Kit
1.1.1 Interface Protocols
The Lassen-SK8 operates using either of three protocols — Trimble Standard Interface
Protocol (TSIP), Trimble ASCII Interface Protocol (TAIP), and NMEA 0183 and are
physically located at the following ports:
• Port 1 TSIP or TAIP
• Port 2 NMEA 0183
Port 1
TSIP is a powerful binary packet protocol that allows the system designer maximum
configuration control over the GPS receiver for optimum performance in any number of
applications. TSIP supports over 40 commands and their associated response packets for
use in configuring the Lassen-SK8 receiver module to meet user requirements.
TAIP is designed for easy integration using programmable ASCII characters in the form
of 2-character message types which provide position.
Port 2
NMEA 0183 is an industry standard protocol common to marine applications. NMEA
provides direct compatibility with other NMEA-capable devices such as chart plotters,
radars, etc. The Lassen-SK8 receiver module supports most NMEA messages for GPS
navigation. NMEA messages and output rates can be user selected as required. RTCM SC-
104 is the GPS industry standard for differential correction data. The receive side of port 2
is configured to accept RTCM data.
1.1.2 Starter Kit Components
The Lassen-SK8 is available in a developer's Starter Kit or as individual boards. The
Starter Kit includes all the components necessary to quickly test and integrate the module.
