Overview
The BT-2010:
•
Utilizes the Trimble Lassen™ SQ GPS receiver module
• Tracks up to 8 GPS satellites and computes location, speed,
heading and time
• Supports 3 communication protocols: TSIP (default), TAIP and
NMEA 0183
• BlueVue supports the GPS receiver by providing the user with
location information in digital and graphical formats.
Changing the default
data settings
The default data output protocol for the BT-2010 is Trimble Standard
Interface Protocol (TSIP), a binary, bi-directional protocol.
The modem can also be configured to output GPS data using one of two
other protocols: Trimble ASCII Interface Protocol (TAIP), and National
Marine Electronics Association Protocol (NMEA 0183).
TAIP is a Trimble-specified digital communication interface based on
printable ASCII characters over a serial data link. TAIP interface
provides the means to configure the Lassen SQ GPS receiver to output
various sentences in response to query or on a scheduled basis. 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.
