Power Supply input

Unregulated +5VDC to +30VDC, reverse polarity protection

Isolation

1500 VRMS Magnetic isolation from Ethernet

Ethernet Port

1 x RJ45 jack, 10/100Mhz autosensing, crossover auto sensing (Auto

MDIX)

Protection

1,500 Volts magnetic isolation between I/O ports and network

Network Protocols

ICMP, IP, TCP, DHCP, Telnet, HTTP

Connection to Network

Ethernet 10BaseT / 100BaseTX

Webserver

Interface

Configure IP address, monitor state of I/O lines, set the Watchdog Timers Output

Reset Value, Set Power on digital output value

Programming

Interface

No device driver needed, just open a TCP connection and send simple ASCII

or Modbus commands. Software drivers give local COM Port interface for

communication.

Utility Programs Find device, configure IP address, test communication with console

Industry Standard Modbus TCP Protocol:

Device works as a Modbus TCP server. Modbus TCP can be used on the input and output lines.

Examples include:

Modbus access

type

Supported Modbus

Familiar ASCII Command Protocol:

When not using Modbus the ED range of devices can use the de facto industry standard ASCII command

protocol implemented in the popular ADAM/NuDAM/EDAM modules. Examples include:

$01M

read the name of device address 01

!01ED-588

device 01 replies that its name is ED-588

$01F

read firmware version number of device address 01

!012.54

firmware version of device 01 is 2.54

@01

read digital input output status of device 01

>1A45

device 01 digital input data= 1A (=00011010) digital output data = 45

(=01000101)

$012

read configuration of device 01

!01400500

device 01 40=typecode, 05 =gateway RS485 port is at 4800 Baud, 00=No
