1DESCRIPTION AND OPERATION OF THE PRODUCT
1.1 THE PRODUCT’S PURPOSE
The Product is intended to receive NMEA messages through four input ports with
RS-232 and RS-422/485 interface support, combine the messages according to the customer
settings and send them through 12 output ports with RS-232 and RS-422/485 interface sup-
port. The Product allows for receiving and combining messages of other standards if they
are separated by “carriage return” (CR) and (or) “line feed” (LF).

1.3 THE PRODUCT’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/О2” 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.
1.3.2 Controls and LED indicators
The Product has a metal casing where functional elements and indicators are located,
see figure 1. For the description of functional elements and indicators, see table 2.
