S STRUCTURE AND OPERATION
1.3.1
General description
NC-217 receives NMEA messages via input ports “DATA_IN1” to “DATA_IN4”,
combines line by line the received messages and repeats them simultaneously as a single
packet to the inputs of “DATA_I/O 1” to “DATA_I/О 2” ports. The data packet, received
on the outputs of “DATA_I/O 1” and “DATA_I/O2” ports, is repeated to the ports “OUT1”
to “OUT12” according to the customer’s settings; while there are data on “DATA_I/O 1”,
the Product operates with this port. When there are no data on “DATA_I/O 1”, in a second
the Product switches to the port “DATA_I/O 2” and receives data on this port unless they
are restored on “DATA_I/O 1”. A user may configure data receive and transmission rate
and rules of combining messages by means of a built-in keyboard and LCD. The LCD indi-
cates data activity by backlight of the active port.
Note – Built-in keyboard and LCD are located under the Product’s top cover.
In case of data loss on port “DATA_I/O 1” and data reception on “DATA_I/O 2”,
and in case of NC-217 power supply failure, dry contacts of alarm relay are actuated.
