COMMUNICATIONS OPTIONS
The EC500 controller provides multiple methods for local and remote communications. A user can
communicate with the controller using 100BaseT Ethernet interface, serial RS485 (Modbus RTU) interface or
GSM modem on RS232 interface. These interfaces provide different level of communication capabilities.
The USB interface is not used for controller communication; it is used for file transfers (to controller) in Host
mode.
ETHERNET COMMUNICATIONS
Ethernet provides the most versatile interface for local or remote communications with the controller.
Refer to:
•
Section EC500 Operation Using a PC/Laptop on page 16 for how to connect to Ethernet interface.
•
Section System Controller Connector Pin-outs on page 100 for pin outs.
A typical connection diagram is as shown below. Multiple devices can communicate simultaneously over the

using a DHCP server.
The network administrator may assign a unique IP address to each EC500 to be connected to
the TCP/IP network.
