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 support.
The Product allows for receiving and combining messages of other standards if they are separated by “carriage return” (CR) and (or) “line feed” (LF).
