2.5.1: Hardware Overview
The Nexus® 1250/1252 with the 10/100BaseT Ethernet Option (INP200) has all the
components of the standard Nexus® 1250/1252 plus the capability of connection to a
network through an Ethernet LAN or through the Internet via Modbus TCP, DNP3 LAN/
WAN (1252 only), HTTP, SMTP, FTP and/or DHCP.
The Internal Network Option of the Nexus® meter is an extremely versatile communi-
cation tool. The INP200:
• Adheres to IEEE 802.3 Ethernet standard using TCP/IP
• Utilizes simple and inexpensive 10/100BaseT wiring and connections
• Plugs right into your network using built-in RJ45 jack
• Is programmable to any IP address, subnet mask and gateway requirements
• Communicates using the industry standard Modbus/TCP and DNP3 LAN/WAN over
Ethernet (1252 only) protocols
2.5.2: Hardware Connection
Use Standard RJ45 10/100BaseT cable to connect with the Nexus® meter. The RJ45
line is inserted into the RJ45 Port on the face of a Nexus® meter with the INP200
Ethernet Option.
2.5.3: Software Overview
To make the software connection, follow these steps:
1. Using Port 1 or Port 4 (RS485 connection), connect a PC to the meter. An RS232/
RS485 Converter may be required (Example: Electro Industries Unicom 2500).
