Introduction

The dS3484 is an Ethernet connected relay module featuring 4 channels of 16Amp 250Vac

relays. Each relay has both normally open (NO) and normally closed (NC) as well as the

common available on three terminals.

In addition to the relays, the dS3484 has 8 digital I/O channels and 4 x 10-bit analogue input

channels (0v-3.3v input range).

The dS3484 requires a 12v 1Amp power supply such as this one:

http://www.robot-electronics.co.uk/universal-12vdc.html

The dS3484 has four built in control methods.

Primary control method is graphically by using its built in secure website.

Secondary control may be one of:

ASCII - type in commands via a program such as PuTTY.

Binary - Command set using binary codes

Modbus – Functions 1, 4, 5 and 15 supported

And if you should wish to modify the supplied firmware – you can.

Behind the scenes there is dScript, a powerful multi-threaded operating system and

programming language. The supplied firmware is written in dScript as well as HTML, CSS and

Javascript on the webpages and the full source is in the separately downloadable dScript

support package.

You do not need to use dScript at all, but its great to know its there - just in case you do.

Getting started

Start by plugging in the Ethernet cable to connect the module to your network, and the 12v

jack plug from your adapter. Switch on and the first thing you will note is that the blue LE will

flash 3 times. This indicates that the control firmware is loaded on the module. (If the blue led

does not flash you will need to load in the control firmware. Don't worry, this is very easy to

do. Just go to the chapter on installing the firmware and follow the instructions there).

If you are using a Win7/8/10 PC, open your browser and into the address bar (not the search

bar) type:

http://dS3484/index.htm

You should now see the application webpage and you can control relays and I/O's.

Locating the IP Address

If you are not using a windows PC then you will need to find the IP address of the module.

The simplest method is connect the module (Ethernet, USB then lastly, Power) and load up the

dScript editor.

Go to Module Select Port and make sure the correct serial port is selected as illustrated above.→

Now go to Module IP Address and the current IP address is displayed.→

Make sure the Ethernet is connected before you apply power. If you plug the Ethernet cable in

after the power, the module will already have booted with a default IP address.

Alternatively, you can find the IP address of the module by checking your HCP server. If you

have a HCP server on your network (your router is normally the HCP server) then the

dS3484 will get its IP address from that. Log on to your router and navigate to the LAN client

list.

Above is the entry from our ASUS RT-N66U router. So now you type:

192.168.0.64/index.htm

into your browser address bar and you should see the application webpage shown on the

previous page.

dS3484

dS3484 User Manual v4.03

If you prefer, you can download a java program that will run on Windows, MAC or Linux, and

will list all of our modules that are connected to your LAN. evantechModuleFinder.jar

If you do not have a HCP server the dS3484 will use a default IP address of 192.168.0.123 so

make sure your PC is on the same subnet of 255.255.255.0 and its IP address is

192.168.0.xxx

dS3484 User Manual v4.03

Configuring the dS3484

There are a set of configuration pages to get the dS3484 operating as you want it. These

pages are all _configx.htm, (that's a leading underscore character).

ie.

_config.htm

_config2.htm

Anything that starts with _config is considered a special name for configuration pages and can

only be seen if you have the the USB cable plugged in and connected to your PC.

Why only if the USB cable is plugged in?

Its an additional security measure. After you have configured and deployed the module, you

really don't want these configuration pages available for others to change. So with the USB

cable disconnected the _config pages are not available. If you try to access them you just get

served a “not authorised” page instead.

So for now, you do want to look over the config pages. If you have a Win10, Linux or MAC PC,

you can go right ahead and plug in the USB cable. These machines will install their own USB

drivers. We won't be sending anything to the board, its just the presence of the USB

connection that enables the config pages to be served. If you have a Win7 or Win8 PC you will

need to install the drivers. (go to the chapter on installing the firmware and follow the

instructions there).

With the USB cable connected, browse to:

192.168.0.64/_config.htm

(substituting your IP address)

Status age

You should now see the following page:

This status page shows you the system and application firmware revisions as well as the

supplied voltage to the board and its internal temperature.

If you hover your mouse cursor over the menu buttons on the left, the help panel will give you

an overview of each one.
