Introduction

BEM105 is an Wide Supply Input, Ethernet Remote Relay Module, with 8 output channels, and

provide with both enclosed and open type housing. Its Ethernet connector provides 10/100baseT

interface.

It supports EasyBus-TCP, HTTP control and Internet control protocols, suitable for being used

with servers, computers, mobiles, routers, etc., to provide remote control and monitor. You can also

define the port number for HTTP by yourself, to realize Router Port Forwarding.

With DHCP functions, it doesn't need to make any settings anymore in field. So just plug and

play, power it on and then enjoy your remote control.

BEM105 is a new generation product with more functions and higher stability. Control mode

"toggle" and "automatic cycle operation" are provided additionally.

3. Easy Start

A Practical step-by-step operation guide for starters

This part is a step-by-step tutorial explaining how to start with BEM105. We'll not discuss too

much details here. The only idea here is to make it work by minimum steps. For more

information, please refer to later chapters.

3.1 HTTP Mode

1. Connect BEM105 with your routers or computer via a standard Ethernet cable. And then

power it on with 5 - 24VDC power supply. (see fig.1.1 at page 2)

2. Open any Browser, for example Chrome is used here as demonstration. Please enter URL:

http://192.168.1.105/k01=2. Relay channel 1 will be toggled, and also a message will be returned

to your browser. Congratulations!

3.2 LAN Mode

1. Connect BEM105 with your routers or computer by Ethernet cable, and then power it on with

5 - 24VDC power supply. (see fig.1.1 at page 2)

2. Open any TCP test tool (if you don't have any, or you don't know what a TCP test tool is, you

can use BE-Manager, it is within our software package). Open it and see the following Fig.1.2:

Fig.1.2

3. Click "Connect" button, and wait for module connected. Then, it is able control the relay

module. Click "CH1 OFF" button, and the relay channel 1 will be switched on. See Fig.1.3

3.3 Internet Mode:

1. Connect BEM105 with your routers or computer by Ethernet cable. And then power it on with

5-24VDC power supply. (see fig.1.1 at page 2)

2. Open "Hello Brick" app for android at any android phone, register a user and then have fun

with Internet control. No other need at relay module is necessary.

3. If you need online help or need to contact us for customized functions, please click the bottom

right red "online help button". One of our daily on duty R&D engineer will talk to you directly.

4. Functionality

4.1 Basic Network Communications

The main method of communication to BEM105 is a standard Ethernet communication.

This communication protocol makes use of Network Sockets or HTTP protocol to create

point to point tunnels that data can flow through bi-directionally. In this way, the computer

that is controlling the relay can send commands and shortly thereafter receive the

response through the same Socket/Web Page.

Communications

In most programming languages, all you need to do to open a socket is to import the

appropriate plug-in, build the socket object, and connect the socket using the IP Address

and Port Number of the target device.

MAC Address

You can find the MAC Address of the module at the simple starter manual delivered

together with module package.

4.2 Save Parameters

After power cycle, BEM105 will lose its parameter modifications if you don't actively

require it to save modified parameters into internal nonvolatile memory. For examples, IP

Address, Gateway address and Net mask.

Assuming module current IPAddress is 192.168.1.105 for all the following commands.

Save parameters

To save parameters:

Web access URL:

http://192.168.1.105/save=1

Socket command text:

save=1;

4.3 Reboot

Send the module a restart signal so it will restart itself. Some parameters modifications

are only effective after a reboot or power cycle. Relay contact outputs are still in

control during reboot process, under default setting, module will be keep the contact

status unchanged during this reboot process. Parameters modifications will be lost if you

don't save them before reboot or power cycle operation.

Assuming module current IPAddress is 192.168.1.105 for all the following commands.

Reboot

www.BrickElectric.com

To reboot device:

Web access URL:

http://192.168.1.105/reboot=1

Socket command text:

reboot=1;

4.3 DHCP Function

BEM105 supports both DHCP and static IP Addressing. For communication reliability, we

recommend using a Static IP Address when you feel comfortable doing so. This will

ensure that the device will always be where you expect it to be, when you try to connect to

it.

DHCP stands for Dynamic Host Configuration Protocol and basically means that your

router will assign the first available IP Address in the list of IP Addresses Range to your

device. This technology makes network devices very easy to use, but it is not as reliable

because in certain circumstances it will cause the IP Address it assigns to change. DHCP

mode is recommended when you only use Internet control, or your local software is able

to detect module IP changes.

Assuming module current IPAddress is 192.168.1.105 for all the following commands.

Enable/Disable DHCP

Note: modification only effective after parameter saving and module reboot.

To Enable DHCP:

Web access URL:

http://192.168.1.105/dhcp=1

Socket command text:

dhcp=1;

To Disable DHCP:

Web access URL:

http://192.168.1.105/dhcp=0

Socket command text:

dhcp=0;

4.4 Static IP Address

This technology is the antithesis of DHCP in that it is manually set IP address and does

not dynamically change without direct action. The disadvantage of this method is that, if

done incorrectly, can make the module unreachable through any standard means. This

usually happens when an IPAddress is statically set to an IPAddress outside of the range

of the router, or another device on the network obtains this IP address via DHCP. If this

happens, see the section of this guide titled “Reset Function”. This method is the preferred

and more reliable way to handle network IP Address allocation. For improved reliability,

the IPAddress assigned to this Module should be reserved on your router.
