Summator-combiner of NMEA signal (sentences)
NC-217
NC-217 connection to the PC through USB-port facilitates settings of input and out-
put ports.
The Product is equipped with a special output “ALARM OUT_AU-106”, based on
closing and opening of relay dry contacts; this output enables to notify personnel about
emergency operation of the Product, see figure 6.
Figure 6 – Dry contacts status of “ALARM OUT_AU-106” output
Dry contacts are actuated in case of input data loss on “DATA_I/O 1” port; in this
case, the Product starts to receive data on “DATA_I/O 2” port.
Attention!
Powered from terminal “Pwr_Out”, an alarm unit AU-106 will be
de-energized in case of supply voltage failure on “POWER IN” terminal of the Product.
If a user needs to ensure alarm signaling of the Product’s power failure along with the
main/standby ports switching,
AU-106 should be powered from SB
AU-106 or similar unit that causes closing or opening of relay dry contacts may be
connected to “ALARM OUT_AU-106” alarm output of the Product. Terminal “ALARM
OUT_AU-106” includes a special group of contacts “Pwr_Out” intended to power supply
an alarm unit. Voltage on “Pwr_Out” power terminal is equivalent to voltage on
“POWER IN” terminal.
Depending on the operation principle of AU-106, one of the following connection
types may be used:
a)
alarm actuation by closing of relay contacts, see figure 7;
b)
alarm actuation by opening of relay contacts, see figure 8.
Actuation mode of AU-106 is selected by jumper JP2 located on the AU-106 printed
circuit board.
