Chapter 12: Ethernet  
Communications to the inverter is via Ethernet on the Control Module.  This allows access to: 
  The PDQ and PDD PC programming tools 
  The Modbus TCP server (see Appendix A - Modbus TCP) 
  The HTTP server (see section below) 
  Application access to the Ethernet including peer-to-peer communications 
  IEEE 1588v2 Precision Time Protocol 
 
The Ethernet operates at 10/100 MHz, half/full duplex. Internet Protocol version 4 (IPv4) is supported.  
The AC30P or AC30D has a built-in Ethernet switch with two external Ethernet ports allowing for daisy chaining of inverters. 
Connecting to the Inverter 
RECOMMENDED CABLE 
CAT5e screened or CAT6 screened Ethernet cable is recommended. 
 
AC30V 
Insert the Ethernet cable as shown below on an AC30V.  Connection is recommended via an Ethernet switch.
