ET9500 NETWORK WIRE CONNECTIONS

3.1 ET9500 Ethernet Connection to Network (For ET90000 and BEMS that uses Ethernet)

• Connect the ET9500 using a standard CAT5 Ethernet cable via a hub, switch or router
to the connector on the bottom of ET9500 (see Figure 6).
NOTE:
• The ET90000's MUST be installed and communicating on an Ethernet network.
All connections need to be on the same subnet. (Section 4.1 & 4.3)
•

3.2 ET9500 RS485 Connection to Network (For BEMS that uses RS485)

• Connect the ET9500 to the RS-485 network wires at the 3-pin RS-485 (Field) connector
on the top of ET9500 (see Figure 7).
o Connect RS-485+ and RS-485 – to Field connector.
