OPTO Inputs

The differential opto-isolated inputs are designed to handle

a variety of NMEA 0183 device output specications.

Please determine (from device manufacturer’s information)

if the device(s) required to be connected to the NDC-4

conforms in full to the NMEA 0183 network communication

standard.Ifitdoesnot,theexibleNDC-4inputsshould

stillbecapableofinterfacingwiththedevice,thoughthisis

not guaranteed.

Thediagramaboveshowsatypicalinstallationwithboth

fully compliant NMEA devices with differential inputs/

outputs, and non-differential output devices.

Note: All NDC-4 inputs are identical and the connections

shownareexamplesthatcanbeusedoneveryinputport.

NMEA Talker Devices 1 and 2: These devices conform in

full to the NMEA 0183 standard. Talker 1 shares the same

connection ID’s as the NDC-4, so connection is a simple

matter of matching the ID’s. Connect ‘+’ to ‘+/A’ and ‘-’ to

‘-/B’ or ‘A‘ to ‘+/A‘ and ‘B’ to ‘-/B’ (refer to gure 2).

NMEA Talker Devices 3 and 4: These devices do not

conform completely to the NMEA 0183 standard. However,

byconnecting‘+‘ to ‘+/A‘ or ‘Data/Signal’ to ‘+/A‘ and ‘G/

Ground’ to ‘-/B’ the NDC-4 should receive the NMEA data

correctly.

ISO-Drive Outputs

The ISO-Drive outputs are capable of driving up to 10

NMEA 0183 fully compliant listening devices, or a mixture

of NMEA 0183 devices and a Personal Computer (PC)

communication port. However, if you wish to maintain

isolation between all devices, then only one listening

deviceshouldbeconnectedtoanISO-Driveoutput.

NMEA Listener Device’s B and C: These devices

conform in full to the NMEA 0183 standard and their

connection ID’s match that of the NDC-4.

Personal Computer: Whilst the OPTO IN 0 and ISO-

Drive0provideabidirectionalRS232compatibleportfor

connectiontoaPC,theISO-Drive1outputisalsocapable

ofbeingreadbyaPC’sRS232port.Simplyconnect‘+/A’

to ‘Rx’ and ’-/B’ to ‘G/Ground’ on a standard D-type

connector.See“Figure26-DB9Connection” onpage8

of the “Full user manual” available on the CD and from

www.actisense.com for a diagram of this wiring

connection.

NMEA Listener Device A: This device does not conform

infulltotheNMEA0183standard.However,byconnecting

‘+/A‘ to ‘+‘ or ‘Data/Signal’ and ‘-/B’ to ‘G/Ground’ the

deviceshouldbeabletoreceivetheNMEAdatacorrectly,

though this is not guaranteed.
