will automatically go into the talk/listen mode and normal signal acquisition will be disabled.
When the USB cable is removed the instrument will automatically return to acquisition. If the
instrument is connected to a PC through the RS-232 port, once the PC sends a message to the
instrument, the instrument will automatically go into the talk/listen mode and normal signal
acquisition will be disabled... but, removing the RS-232 cable does not cause the instrument to
revert to acquisition mode, as with the USB connection. The instrument will need to be powered
down and re-powered to return to signal acquisition mode.
Important Notes:
1.
The proper cable to use is a USB Series ’A’ male to USB Series ’B’ male. Specified
maximum USB cable length for Low-Speed peripherals is 3-meters (9.84 ft.).
2.
The proper cable to use is a D-sub 9-pin male to female Extension Interface Cable (not a
Null Modem cable).
3.
If both the USB and RS-232 ports are connected at the same time, only USB port will
operate as USB is inherently faster than RS-232.
4.6.3 Using the LogView-R Utility
With the supplied LogView-R software, any computer using the Windows operating system that
contains a USB or RS-232 port can download data records logged into the PathAlign-R. First,
install the supplied LogView-R Data Log Utility software into your computer system. Ensure that
the computer and the PathAlign-R are connected. Next, run the LogView-R utility, and in the
lower left corner of the utility’s display, near ”Connection”, select the appropriate ”COM1” or
”COM2” for RS-232 or ”USB” for USB. After a few seconds the circle next to the ”Connection”
will turn green, indicating that the program is communicating with the instruments.
4.6.4 Download / Save Data Records
Once communication has been established, the [Read Instrument and Save Data] soft-button
will be enabled. Selecting (clicking on) the [Read Instrument and Save Data] soft-button initiates
the download/save function and all records stored in the memory of the PathAlign-R instrument
will be saved as a composite file to your hard drive (in the same location that LogView-R
resides) and displayed in the LogView-R program (displaying fifteen records at a time). Scrolling
up and down will show all the records downloaded. This operation does not clear the
instrument’s memory, but simply downloads and saves a copy of the logged data to the
computer.
Note:
If the GPS receiver was not locked at the time of the original recording, the Latitude
and Longitude data will have the word ’Unknown’ in those data fields. If Date and Time data
are captured, the data will appear, otherwise, the word ’Unknown’ will also appear in those
data fields.
