3.4.5 Connecting input/output contacts and NMEAcommunication
For connection to other systems following input/output contacts are provided:
1. Alarm output - voltage-free change over contacts, max. 250V AC/1A acctivated in case of broke light
circuit and power/system failure.
2. External alarm accept input - normally open voltage-free contact, when acctivated quits main unit
buzzer only (sound alarm).
For communication with other systems NMEA 0183 communication is provided. ITNSL-01 NMEA 0183
TRANSMITTER and RECEIVER are used as bi-directional interface to transfer external alarm from
Navigation and signal lights controller type ITNSL-01 to external systems and audio alarm acknowledgement
from external systems.
Connect as shown bellow. Connect shield of cables to instrument earth.
