EAD01-103 Operation Under MODBUS Protocol
Ethernet Adaptor – EAD01-103 supports MODBUS protocol based communication. User
can sent MODBUS TCP command to the EAD through the Ethernet interface, EAD will
convert MOSBUS TCP queries to MODBUS RTU protocol and sends to serial side.
User can connect any device to the serial which is supporting MODBUS RTU protocol.
EAD will receive MODBUS RTU response from Serial device. This MODBUS RTU
response will be converted in to MODBUS TCP Protocol and transmits through Ethernet
interface to the User. MODBUS poll software can be used for MODBUS protocol
communication.
Basically network configuration having eight parameters, which are programmable and
explained in section 7.1.If EAD01-103 operates under MODBUS protocol one extra
parameter will come under this section that is
MODBUS
Using this user can Disable and Enabled MODBUS protocol.
Default Setting is Enable.

EAD01-103 Operation Under PPP Protocol
PPP (Point-to-point protocol) is a protocol for communication between two nodes using a
serial interface. This is commonly used to act as the link layer protocol. Ethernet Adapter
EAD01-103 supports point to point protocol based communication. EAD adds network
connectivity to your devices by processing PPP protocol, which is required to send and
receive data over CDMA, GPRS and Dial-up network, so your devices can be remotely
controlled, managed and monitored over the internet. Because of its low cost, it is ideal
for high-volume products, which need low cost. It reduces cost and risk and shortens
development time to add networking capability as a standard feature.

EAD01-103 Operation Under SNMP Protocol
Simple Network Management Protocol (SNMP) is the protocol responsible for allowing
network management stations on a TCP/IP internet work to perform management tasks
with managed devices. The core of the protocol consists of a set of protocol operations
that allow management information to be exchanged between SNMP agents and
managers. Ethernet Adapter – EAD01-103 supports simple network management protocol
based communication. SNMP enabled EAD can be integrated with devices like UPS and
can be used with SNMP managers. Using SNMP EAD, SNMP Manager Queries are
converted in to device protocol and vice versa.
Basically serial configuration having eight parameters those are explained in section 7.2.
If EAD01-103 is using SNMP, 3 extra parameters will come under serial configuration.
The available options are described below
Command Termination
We must set command termination as
Carriage Return (CR)
when SNMP Protocol is
using.
