Actisense products are intended for use in a marine environment, primarily for below deck use. If a product is to be used in a more severe environment, such use may be considered misuse under the Active Research Ltd guarantee.
Warning 1: Accuracy The Actisense NDC-5 is designed to accurately transfer data from input to output. When the NDC-5 is in a Basic Mode no data integrity checking is performed, therefore any incomplete, inaccurate or corrupt data received on a NDC-5 input will be duplicated to the NDC-5 outputs.
NMEA 0183 interconnectivity headaches. The five NMEA 0183 inputs can be routed to any of the two NMEA 0183 outputs, as well as the serial and Ethernet ports* providing a highly customisable network. The bi-directional serial port and Ethernet port also allow for simple configuration and diagnostics using Actisense software.
Connecting to NMEA Devices The ‘A/+’ and ‘B/-’ of the NMEA 0183 device should be matched to the ‘A’ and ‘B’ on the NDC-5. If the NMEA 0183 device has a ground (GND) wire (and no ‘B/-’ wire), simply connect this to ‘B’ on the NDC-5.

NDC-5 in place. Bulkhead Mounting Actisense recommends the NDC-5 is installed using the DIN rail supplied for the most secure installation. However, the NDC-5 can be secured to a bulkhead using the two screw catches on the reverse of the NDC- 5 shown in the diagram below.
NMEA 0183 Multiplexer - NDC-5 Web Browser Configuration Tool The Configuration Tool for the NDC-5 is built-in and can be accessed via the Ethernet connection. As the Configuration Tool is web based it is compatible with all popular web browsers and Operating Systems.
Direct connections or basic Ethernet networks If the NDC-5 is connected directly to a PC (or the Ethernet network does not have a DHCP server), the NDC-5 will communicate using auto-IP by default. The auto-IP process can take up to 60 seconds to complete.

NMEA 0183 Multiplexer - NDC-5 First level NDC-5 diagnostics / fault finding can be performed by observing the LED behavior. The normal behavior of the NDC-5 LEDs is described in the table below. If the LEDs are not behaving as expected, this will indicate a fault in either the device connected to the NDC-5, the wiring/connections, or the NDC-5 itself.
Actisense Technical Support to help trace the issue before considering the return of the product. If the Actisense support engineer concludes that the NDC-5 unit should be returned to Actisense, a ‘Return Merchandise Authorisation’ (RMA) number will be issued by the support engineer.
