RJ-11 Telephone Line allows a Nexus Meter with the Internal Modem Option to communicate with
a PC. No other hardware is necessary for this easy-to-use connection. The Nexus 1250/1252 Meter
with the Internal Modem Option can connect via RS-485 to other Nexus Meters in local or remote
sites in a daisy chain configuration, as depicted below.
The Nexus Meter with the Internal Modem Option has a unique label; Port 2 is labeled Modem
Gateway. If you are going to use RS-485 to connect multiple Nexus 1250/1252 meters, you MUST
use the Modem Gateway. For more details, see Chapter 10 of this manual.
