19. Appendix E: Serial Data Output
Any of SkyView’s five RS232 serial ports can be configured to output various types of serial data
via SETUP MENU > LOCAL DISPLAY SETUP > SERIAL PORT SETUP. Technical information on the
installation and connection to the serial ports can be found in the Serial Devices section of the
SkyView Installation Guide. To log serial data, you must select either DYNON EMS, DYNON
ADAHRS, DYNON SYSTEM, DYNON ADAHRS + SYSTEM, DYNON ADAHRS + EMS, or DYNON
ADAHRS + SYS + EMS, NMEA OUT (BASIC), or NMEA OUT (FULL) as a Serial Out device, select a
baud rate, and connect the serial port to an external serial device such as a PC. The serial data
can be logged using any standard serial terminal program, a data logger program, or dedicated
data logger device. All numbers are output in decimal except where noted and are standard
ASCII. To view the data using a terminal program, that program should be configured to receive
data in the following format:
 Baud rate: Set baud rate to match the baud rate selected on SkyView’s serial port
 Data: 8 bit
 Parity: none
 Stop: 1 bit
 Flow control: none
Multiple SkyView display systems: SkyView’s serial ports are designed in a way
that allows serial transmission to continue, uninterrupted, as long as at least one
SkyView display is operational. SkyView accomplishes this by only transmitting
from exactly one display’s serial ports in a multi-display system. SkyView manages
which display is the “actual transmitter” automatically to avoid serial port
conflicts. However, the display that transmits is not user-selectable. Therefore, for
reliable serial reception in multi-display systems, a SkyView serial data output wire
should be wired from each display, in parallel, to the external serial device that is
being used to capture SkyView’s serial data. Then, the serial port employed in all
displays (it is useful to use the same serial port on each display for ease of setup)
should be set to output the format desired. If the serial outputs are not configured
in this fashion, serial data will not be seen by your external serial device at all
times.
