2.6.1.1.3 GWUtilities Status Messages
The GWUtilities program produces a variety of status messages on the bottom line of the
program window. Following is a list of status messages and suggested actions, if any.
No response received from gateway
The gateway has not responded to a command sent to it by GWUtilities.
Suggestions:
• Check that the correct port has been assigned in the Gateway Serial Port listbox
• Check that the gateway has been supplied with power
• Check that the cable connection between the gateway and the PC is secure
Failed to open serial port portname
GWUtilities was not able to open a connection to the serial port portname.
Suggestions:
• Check that the correct port has been assigned in the Gateway Serial Port listbox
• Check that any required drivers for the gateway have been installed correctly. You can
do this by opening the Device Manager, opening "Ports (COM & LPT)", and selecting
"Properties..." for the desired port and verifying that the port is operating correctly.
2.6.2 NMEA 2000® Device Selection
Normally, the USB100 translates messages from all devices on the NMEA 2000® network.
However, in some cases you may have multiple devices on the NMEA 2000® network; for
instance, two GPS receivers or two depth transducers. When you have multiple devices of the
same type on the NMEA 2000® network, you should configure the USB100 to translate PGN’s
from only one of those devices. The easiest way to configure these translations is with an
attached Maretron DSM200 Multi-function Graphic Display unit. Please refer to the DSM200
User’s Manual for details on how to configure device selection on a USB100 or copy device
selection settings from a DSM200 to a USB100.
2.6.3 NMEA 0183 Sentences to NMEA 2000® Translations
The USB100 is capable of receiving certain NMEA 0183 sentences from charting software
running on a PC and converting the sentences to NMEA 2000® PGNs for subsequent display
by NMEA 2000® devices. For example, when a PC charting system is in the process of
navigating to a waypoint, it is capable of transmitting certain navigational sentences such that
external equipment can display “rolling road” information. The following table shows the NMEA
0183 sentences received from PC charting systems and the corresponding translations to
NMEA 2000® PGNs. Refer to Appendix B for specific details regarding translations.
