Replace Legacy Lassen SKII Modules
NLC-SKII 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 SKII module.
Mechanical - The NLC-SKII has the same mechanical dimensions as the Lassen SKII. It has the same 8 pin data connector as the SKII and has the same SMB antenna connector (both located in the exact same locations as found on the SKII). The Copernicus II does not require a metal shield, which was an add-on option for the original Lassen SKII.
GPS Protocol - The Lassen SKII 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 SKII supported ODD, EVEN and NO parity with a default of ODD parity. This default setting might affect compatibility for some customers.
Performance: The Copernicus II is a far superior product to the SKII. It supports more concurrent satellite tracking, faster startup and is much more sensitive.
WHAT IT REPLACES:
