dS3484 User Manual v3.01

Introduction

The dS3484 is an Ethernet onne ted relay module featuring 4 hannels of 16Amp 250Va

relays. Ea h relay has both normally open (NO) and normally losed (NC) as well as the

ommon available on three terminals.

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

hannels (0v-3.3v input range).

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

http://www.robot-ele troni s. o.uk/universal-12vd .html

The dS3484 has four built in ontrol methods.

Primary ontrol method is graphi ally by using its built in se ure website.

Se ondary ontrol may be one of:

ASCII - type in ommands via a program su h as PuTTY.

Binary - Command set using binary odes

Modbus – Fun tions 1, 4, 5 and 15 supported

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

Behind the s enes there is dS ript, a powerful multi-threaded operating system and

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

Javas ript on the webpages and the full sour e is in the separately downloadable dS ript

support pa kage.

You do not need to use dS ript at all, but its great to know its there - just in ase you do.

dS3484

dS3484 User Manual v3.01

Getting started

Start by plugging in the Ethernet able to onne t the module to your network, and the 12v

ja k plug from your adapter. Swit h on and the first thing you will note is that the blue LED will

flash 3 times. This indi ates that the ontrol 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 sear h

bar) type:

http://dS3484/index.htm

You should now see the appli ation webpage and you an ontrol relays and I/O's.

dS3484

dS3484 User Manual v3.01

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 onne t the module (Ethernet, USB then lastly, Power) and load up the

dS ript editor.

Go to Module Sele t Port and make sure the orre t serial port is sele ted as illustrated above.→

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

Make sure the Ethernet is onne ted before you apply power. If you plug the Ethernet able in

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

Alternatively, you an find the IP address of the module by he king your DHCP server. If you

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

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

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 appli ation webpage shown on the

previous page.

dS3484

dS3484 User Manual v3.01

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

will list all of our modules that are onne ted to your LAN. Devante hModuleFinder.jar

If you do not have a DHCP 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

dS3484 User Manual v3.01

Configuring the dS3484

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

pages are all _ onfigx.htm, (that's a leading unders ore hara ter).

ie.

_ onfig.htm

_ onfig2.htm

Anything that starts with _ onfig is onsidered a spe ial name for onfiguration pages and an

only be seen if you have the the USB able plugged in and onne ted to your PC.

Why only if the USB able is plugged in?

Its an additional se urity measure. After you have onfigured and deployed the module, you

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

able dis onne ted the _ onfig pages are not available. If you try to a ess them you just get

served a “not authorised” page instead.

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

you an go right ahead and plug in the USB able. These ma hines will install their own USB

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

onne tion that enables the onfig 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 able onne ted, browse to:

192.168.0.64/_ onfig.htm

(substituting your IP address)

dS3484 User Manual v3.01

Status age

You should now see the following page:

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

supplied voltage to the board and its internal temperature.

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

an overview of ea h one.

dS3484

dS3484 User Manual v3.01

Network age

Noti e that everything below the Host Name is greyed out and an't be hanged. This is

be ause the “Enable DHCP” box is he ked and all the greyed out fields are supplied by the

DHCP server. Although a qui k way to get you onne ted, we really do not re ommend this as

the DHCP server an assign a different IP ea h time you power up. If you want to ontrol this

module from the internet while you are away from the premises then you will be setting up

port forwarding on your router whi h requires a fixed IP address.

So lets do that first.

Un he k the DHCP box and you an then set all the other fields. Noti e that the Red “Update

Pending” light omes on. It indi ates there are hanges whi h have not yet been written to the

flash memory. It will go off again 5 se onds after you stop hanging anything.

Choose an IP address for the module, something outside of the DHCP settings on your router

so it will not assign anything to that address.

The subnet mask, Gateway and DNS an all be left as the defaults.

Network hanges only take effe t after the next re-boot, so wait until the “Update Pending”

light goes out and give the reset button on the module a qui k press. The Green Led will light

and the Blue led will flash 3 times. You will now find the module at your new IP address. If the

Red led omes on after you press the reset button, its be ause you pressed it for too long (and

entered bootloader mode). Just have another go with the reset button for a bit less time.

Your browser won't know you have hanged the IP address so it will still be showing the old,

now dead page. Make sure you hange to your new IP address and load the page again.

dS3484

dS3484 User Manual v3.01

TCP/IP age

The TCP/IP tab allows you to sele t one of three ommand sets to ontrol the module. These

are independent of, and separate to the HTML webpage ontrol.

Cli king on one of the four he k boxes will sele t that ommand set. Only one ommand set

may be sele ted. You an disable all TCP/IP ommand sets by li king on an already sele ted

box.

The ASCII ommand set is text based. You an use any program that an send text over

TCP/IP. We use PuTTY in raw mode. The Binary ommand set operates in a similar way to our

ETHxxx range of boards (but uses different ommands), by sending binary ommands to the

module. AES Binary adds en ryption. Note the AES key MUST be 32 bytes long. We have test

appli ations written in C# and Java to demonstrate AES en ryption.

dS3484

dS3484 User Manual v3.01

When sele ting the Modbus ommands, an additional set of onfiguration boxes are available.

These allow you to sele t the UID, normally you will leave this at the default of 1. The dS3484

will respond to ommands on this UID. If you send any other UID it will be treated as the

address of a Modbus module onne ted to the RS485 port. Commands to other UID’s will be

onverted to Modbus RTU format and sent out on the RS485 port. Any responses will be

onverted ba k to Modbus/TCP format and returned to you.

The se ond box sele ts the baud rate of the Modbus RTU line and the third box sele ts even,

odd or no parity.

The Modbus ommand set implements fun tions 1, 4, 5 and 15.

When sele ting the Modbus ommand set, make sure you sele t port 502 whi h is the offi ial

port number for Modbus over TCP/IP.

A full des ription of the ommands is in the “Command Sets” se tion later in this manual.

dS3484 User Manual v3.01

Web age security

Allows you to prevent unauthorised personnel from a essing the appli ation webpage or using

it to ontrol the module.

Leaving the Se urity Password blank will disable it and allow everyone to a ess the appli ation

page to ontrol the module.

To enable password prote tion enter a password into the Password box. You an use any

hara ters from the ASCII hara ter set from 0x20 to 0x7E ex ept “ (0x22). It may be up to

200 hara ters long and you don't have to memorise it, so make it a long one with plenty of

upper ase, lower ase, numbers and symbols.

A essing a spe ial webpage, _pw.htm, will install the password on your browser. To do this

make sure the Enable _pw.htm box is he ked.

When the “Update Pending” light goes out, re-boot the module and go to

yourIP/_pw.htm

dS3484

dS3484 User Manual v3.01

You will see something like this:

The password is now loaded on your browser. Do the same for any further browsers you want

to enable. When you have done un he k the “Enable _pw.htm” box to prevent anyone else

from loading the password. When the “Update Pending” light goes out re-boot the module

again.

The default port used by html webpages is 80. You an hange this if required. If you do so

then you will need to in lude the port number in the address.

If you hange the port to 2345 then the webpage will be at:

YourIP:2345/index.htm

For example:

192.168.0.123:2345/index.htm

dS3484

dS3484 User Manual v3.01

Configuring relays

The next tab allows you to set the names of the 32 relays that will be displayed on the

appli ation page.

Use the Relay No. box to sele t the relay to onfigure. There are 32 relays available. Relays 1-

4 are the physi al relays on the module. Relays 5-32 are virtual relays, they have no physi al

presen e but otherwise behave the same as the real ones. I/O lines may be linked to virtual

relays to provide additional physi al outputs, see next se tion for details.

Names may be up to 20 hara ters long,but keep them shorter if you want to use a phone as

the ontroller. Here we have renamed relay 1 as “YardLights” and those 10 hara ters are a

omfortable size on a verti al phone s reen.

dS3484

dS3484 User Manual v3.01

Relay automation

There are a set of ontrol boxes that provide for autonomous relay operation. If you just want

to ontrol the relays from the webpage or using one of the TCP/IP modes, then leave these

boxes blank.

Relay No. box

This sele ts the relay you wish to onfigure. There are 32 relays available. The first 4 relays

are the a tual relays on the module. Relays 5-32 are virtual relays. They have no physi al

presen e but otherwise behave identi ally to the real ones. They an provide additional

pro essing and a larger ontrol surfa e to your appli ation.

Pulse/Follow box

If you pla e a number in this box then that is the pulse time for the relay in mS (1000mS = 1

se ond). The minimum value is 100mS. The maximum is 2147483647 (more than 24 days).

When the relay is toggled on, timing begins and at the end of the time period the relay goes

off again. If the button is pressed again during timing then the timing is restarted.

The above example will turn off the yard lights after 30 minutes. 1800000 mS is 1800 se onds.

1800 se onds is 30 minutes.

It also possible to insert a boolean equation into the box. Boolean equations are just simple

equations that evaluate to a 0 or 1.

For example Relay 1 is referred to a R1. Input1 is referred to as D1 (Digital 1). Analogue input

1 is referred to as A1.

dS3484

dS3484 User Manual v3.01

Here's a very simple example:

Enter R2 into the Relay 1 Pulse/Follow box. This will make relay 1 opy whatever you do to

Relay 2. Try it!

Now hange it to !R1.

The ex lamation mark is read as “Not R1”. Now relay 1 will always be the opposite of relay 2.

Try it.

Boolean equations may be used for ontrolling relays and other obje ts su h as email.

See the “Boolean equation” se tion later in this manual for full do umentation.

dS3484

dS3484 User Manual v3.01

Set Reset & Toggle boxes

When used, these three ontrols ontain boolean equations. The “Set Relay” box will set the

relay when the boolean equation be omes true. The other two boxes reset and toggle the relay

when the boolean equation be ome true.

This is important! The Set, Reset and Toggle ontrols are transitory (edge triggered) ontrols.

The relays are only affe ted at the moment the boolean equation be omes true. This differs

from the Follow box where the relay ontinuously follows the output state of the equation.

In the previous example where we pla ed R2 in relay 1’s Follow ontrol, relay one will always

be the same as relay 2. If relay 2 is off and we li k relay 1 (YardLights) nothing will happen.

However if we want relay1 to be ontrolled by relay 2 as above, and also want to be able to

toggle it on/off from the webpage, we an put R2 in the “Set Relay” box and !R2 in the “Reset

Relay” box.

Try it.

Power-up restore

When he ked, the relay is restored to the previous state it had when power was lost. If the

relay was on when power was lost or the module was turned off, then the relay will be turned

on when the module is powered up again.

dS3484

dS3484 User Manual v3.01

Naming I/O's

The I/O Names tab is used to assign meaningful names to the I/O terminals.

As with relay names these may be up to 20 hara ters long, but do he k it looks ok on a

mobile devi e or whatever you are using to ontrol the module.

Connecting I/O to Virtual Relays

Any of the eight digital I/O lines may be onne ted to a virtual relay. This gives the digital

output the same automation apabilities as the relays. Enter the relay number in the link box

as shown above. Any relay may be sele ted for an I/O.
