General

Product description

The RCU 10 consists of a communications module with

integrated GSM modem, antenna for the GSM modem

and a separate power supply unit for plugging into a wall

socket. The antenna can be located outside the enclosure.

The RCU enables operations to be controlled and moni-

tored using a computer or by a principle system (SCADA-

system), which can read the ModbusTCP-protocol, in a

local network or via the internet.

It is possible to connect to the RCU two independent

switch functions to detect external events such as a move-

ment alarm or freezing protection.

Note that all conﬁguration of the unit requires that a com-

puter with support for ”JAVA-applets” is connected, even

if only text messaging is going to be used.

The RCU enables operations to be controlled and moni-

tored using a computer connected to a local network or

via the Internet. The integrated GSM module also enables

control and monitoring by sending text messages from a

mobile phone. For the GSM function to work, the commu-

nications module must be equipped with a valid GSM sub-

scription. This may for example be a cash card or a special

telematics subscription.

If a SIM card is used, it must be configured

so that a PIN code is not used to obtain

connection. This can be done in a mobile

telephone or by the service provider.

NOTE!

Quick start guide

Double click on the line with your RCU in the

Netbiter window. A new window opens.

The RCU is connected to a local network:

Enter the network settings that apply to your net-

work. To obtain the necessary information concer-

ning your network settings, please contact your

network administrator.

The RCU is directly connected to the computer:

Enter the ﬁrst three values from your computer’s IP

address, for example, 10.1.1. The fourth is set to

a value other than the one used in computer’s IP

address.

Example:

If the computer has the IP address 10.1.1.1 then set

the RCU address to 10.1.1.X, where X can be set

to any number between 2 and 254 (not 1, as this is

used by the computer in this example).

Complete setting by giving a valid password and

press ”Set”. The factory-set password is ”admin”.

Write down the password and keep it in a safe pla-

ce. If the password is lost the RCU must be returned

for reprogramming

Installation

Network connections

The RCU has a connection (5) for 10/100-Mbps Ethernet.

Connect the unit to a network, or alternatively direct to a

computer with the Ethernet cabling. For connection to a

router or a hub/switch a straight-through cable must be

used, and for direct connection to a computer a crossover

cable must be used.

A network with the RCU connected to a router or hub/

switch is recommended. For connection direct to a compu-

ter with Internet connection, two network cards are requi-

red in the computer, and it must run continuously in order

to provide the RCU access to the Internet.

Internet connection is not necessary to be able to install

and conﬁgure the unit, but is required for access to the

unit via the Internet.

Installation

GSM modem

The RCU contains a GSM modem that can be used for sen-

ding and receiving SMS messages, and to access the RCU’s

web pages.

Antenna

The RCU is delivered with an antenna, that is initially kept

rolled up inside the outer casing. If reception at the instal-

lation site is poor, try moving the antenna outside the box.

The antenna section has a piece of self-adhesive tape that

can be used to secure the antenna, for example to a win-

dow.

SIM card

The modem requires a 3.3-V SIM card. See the illustration

below for installation instructions. The SIM card must be

conﬁgured so that a PIN code is not used to obtain connec-

tion. This can be done in a mobile telephone or by the ser-

vice provider. For a telephonic data connection to the RCU,

the SIM card needs to have a special telephone number for

computer communication. Refer to the section “Web inter-

face – Settings” > “Modem” for further information.

If a cash card is used, remember to reﬁll it at regular inter-

vals so that communication is not cut off by the operator.

Digital inputs

The RCU has two digital inputs (7) (optically isolated) for

connection of an external signal. The inputs shall be 10

– 24 VDC for an active high signal and 0 – 2 VDC for an

inactive signal.

General

The RCU has a preset IP address: 10.200.1.1.

NOTE! Images and settings on the following pages may

show some difference, depending on the browser, settings

and the version of the RCU, as well as the heat pump con-

ﬁguration.

RCU conﬁguration software

The RCU conﬁguration software is a PC-based program

that can be used to prepare different network parameters

in the RCU. The program can search for RCU units on an

Ethernet network, after which the IP address, network

mask, gateway, DNS, etc. can be set. DHCP can also be

activated in the unit.

Install by running the installation program Setup-

NetBiterConﬁg.exe that is on the supplied CD.

System requirements

Pentium 133 MHz•

5 MB free hard disk space•

Windows 95/98/ME/NT/2000/XP•

Network card (Ethernet)•

If a different operating system than Windows is used the

conﬁguration software can not be used. Then connect to

the RCU’s preset IP address in the web browser and use the

web interface to change the network settings. See section

“Starting” – “Logging in”.

Search for connected units

When the program starts, it will automatically search for

an RCU network connection. A list will be displayed of all

units that are found. A new search can be made by pres-

sing the “Scan” button.

A DHCP server can be started under Advanced options

(only active when Netbiter Conﬁg is running). Use this al-

ternative to ﬁnd an RCU which is unintentionally set to use

DHCP in a network where DHCP servers are missing.

precise password must be entered in

respect of upper and loser case characters.

NOTE!

Only A-Z, a-z and 0-9 are permitted to be

used in the user ID and password, the sym-

bol characters cannot be used.

NOTE!

If the password is forgotten, there is no

way to retrieve it. The RCU must be retur-

ned to NIBE where a complete reset will

take place.

All the settings that have been made,

including user settings, will disappear.

NOTE!

Changing IP settings

Double-click on the desired unit in the list to change the IP

Host name: Host name for RCU (any)

The preset password is ”admin”.

On pressing the “Set” button the RCU will restart, after

which the new settings will be activated.

The new settings can be tested by opening a browser and

entering the set IP address. If DHCP is activated, a new

search can be made with the program to see which IP

address has been assigned to the RCU.

If Dynamic IP addressing is used in the local

network, the DHCP server should be con-

figured so that RCU’s MAC-ID retains the

same IP address each time.
