Inserting the Strain Relief Clip

Once the strain relief clip is inserted it cannot be removed. Insert the strain relief clip on the right hand side if 
connecting to an NMEA 0183 Listener or RS232/RS422 receiving device and for bi-directional connections. Insert on 
the left if connecting to an NMEA 0183 Talker or RS232/RS422 transmitting device only.

*NB – Use of the strain relief clip is optional, however it is required in order to remove the screwless header 
from the screwless connector.

Securing Data Wires

To protect against vibration, wrap the supplied cable tie around the terminated wires and in-line with the groove on the 
strain relief clip. Pull the cable tie tight enough that it secures the data wires to the strain relief clip, but not too tight 
that it begins to crush the wire. 

Power Supply and USB Drivers

The USG-2 is powered by the USB connection.

On PC’s with an internet connection, USB drivers should be 
downloaded and installed automatically. Otherwise USB  
drivers can be downloaded from the USG-2 downloads web  
page or are available on the CD provided. To install the  
USB drivers, please refer to the USB Driver Install Manual.
