Introduction

NLC-LP is a GPS receiver based upon the popular Trimble Copernicus II surface-mount receiver. It has been designed to be a fit/form replacement for the end of life Trimble Lassen LP module.

COMPATIBILITY

Mechanical - The NLC-LP has the same mechanical dimensions as the Lassen LP. It has the same 8 pin data connector as the LP and has the same MCX antenna connector (both located in the exact same locations as found on the LP).

GPS Protocol - The Lassen LP supported Trimble's TSIP (Trimble's own binary based protocol), NMEA (industry-standard ASCII protocol) and TAIP (Trimble's own ACSII protocol). The Copernicus II supports all of these protocols.

Serial Interface - the Copernicus II has one limitation which is that the serial port parity is not configurable (only 'NO' parity is supported). Trimble's Lassen LP supported ODD, EVEN and NO parity with a default of NO parity. 

Low Power Mode - the Lassen LP supported a low power mode via pin 1. Copernicus II does not support this mode, hence this feature will not work. Pin 1 is not connected.

Performance: The Copernicus II is a far superior product to the LP. It supports more concurrent satellite tracking, faster startup and is much more sensitive.

WHAT IT REPLACES:

This module can replace all released Lassen LP modules including:

• Trimble 39263-10 Lassen LP (Non RoHS)
• Trimble 39263-15 Lassen LP (RoHS)
