1. Introduction
This is the user manual for eSurvey UA301 smart antenna. It gives basic description
and operation guide which may help user to operate device properly.
1.1 Appearance
UA301 has superior antenna gain, phase difference, quadrature axis ratio
performance to obtain centimeter- level positioning accuracy. The antenna is
integrated with WIFI, Bluetooth and Web user interface. It can be used for agricultural,
machinery assisted driving, engineering vehicles, ships, surveying and mapping and
other fields.
1.2 Pin Ports
The 12-pin port is used for the data communication and power supply. The definition
is as below:
There are two RS232 ports on UA301. The port A is connected to the position board
directly while the port B is not. The port A can be used for NMEA output and correction
data input. The port B (also named as port user) is used for NMEA data output.
1.3 Mounting
The base mounting size on UA301 is 3/4. The convertor 5/8 size is coming with it for
