- It is a conversion device for the signals between bus analog signaland digital signal.
- If need connect with more than 60 substations,we can use ip networkmaster to connect with the analog-to-digital converter.
- 300-call master stationNLS-300 could manage up to 300 substations via connecting with 5 analog-to-digital converters.
- 600-call master StationNLS-600 could manage up to 600 substations via connecting with 10 analog-to-digital converters.
- Dialing master stationNLS-10000 could manage up to 36000 substations via connecting with 600 analog-to-digital converters.
- Connect with master station via LAN(could cross segment and router),connecting with substation via 5-wires cable.
