Alarm notice
The Ouman Ouex M BA controller may emit alarms. Alarm de-
tails are highlighted on the screen in failure mode, and the beeper
sounds.
When there are more than one unacknowledged alarms in the con-
troller, information on the most recent alarm is highlighted on the
screen. After all active alarms are acknowledged, the display quits
the failure highlight mode and the beeper stops.
The beeper can be turned o with active alarms present by press-
ing the ESC button. When you do so the window with details of the
most recent alarm on the screen will close.
To view active alarms, go into the menu
"Alarms-> Active alarms". Unacknowledged alarms are marked with
an exclamation mark at the start of the line.
Some of the information in your Ouex M BA device may be hidden.
You can see the hidden menus by pressing OK for a few of seconds.
Similarly, you can hide them again by pressing OK for a few of sec-
onds. Hiding information that you seldom need to change or look
into makes the UI simpler. When visible, this information is shown
indented.
There may be a maintenance code in use in your Ouex M BA de-
vice. In this case, you can see the information even when it’s locked,
but you can’t make changes to settings without entering the main-
tenance code. Normally, you lock the most critical settings behind
the maintenance code, or settings that require expertise.
There is a symbol in front of a setting that requires maintenance
code.

1.2 Text message (SMS) settings
Use of text messaging requires that the Ouex M BA is connected
to a GSM modem (additional equipment).
System settings > SMS settings
Take the GSM modem into use:
1. Enter your SIM card PIN, if your SIM card has a PIN code request
enabled.
2. Switch the device o.
3. Connect the modem.
4. Switch the power on. The controller initializes the modem and
detects the message center (the message center number is not
visible on the display).
5. Check the signal strength and status of the modem from con-
troller display.

SMS PIN:
If the SIM card has PIN inquiry in use, Ouex M BA device asks you to enter
the PIN.
SMS PIN
Entering the code:
1. Use arrow buttons and press OK to accept each number.
Press ESC to return to the previous digit.
2. Press OK for a number of seconds to accept the code.
Press ESC for a number of seconds to cancel.
Signal strength:
Signal strength is expressed with the following descriptions:
”Excellent”, ”Good”, ”Moderate”, ”Low”, ”Very low” and ”Initialization failed”.
If signal strength is ”Very low” or ”No network”, try changing the modem’s
location or use an external antenna. If the unit displays ”Initialisation
failed,” check that the SIM card is correctly installed.
Approve: Press and hold OK
Cancel: Press and hold ESC
Modem status Explanation / Instructions
Ok The modem is ready for use.
Not connected The modem is not connected or the connection is incorrect.
6. Enter Device ID (optional).
7. Test the SMS communication. Send a message to Ouex M BA:
Keywords. If the controller replies with a message containing a list of
key words, text message communication is ok. If the controller doesn’t
reply, switch power o and on again. You can check the validity of
the subscription using a mobile phone. Insert the SIM card in a mobile
phone, send a text message to another phone and reply. If the mes-
sages go through, the subscription is OK. Insert the SIM card back
to the GSM modem and test SMS communication again. If controller
still does not reply, check that the message center number has not
been inserted manually. Press OK button for a few seconds to display
hidden menus. Remove message center number: clear the rst digit
and press OK button for a few seconds. Switch power o and back on.
Controller retrieves the message center number automatically (the
message center number is not visible on the display).
8. Retest the text message communication.
When Ouex M BA device starts up, it will automatically detect whether the
modem is connected or not and then initialises modem.
Modem status:
You may give your Ouex M BA device a device ID. In SMS communication,
always type the device ID in front of the keyword (e.g. OU01 MEASURE-
MENTS). Note the empty digit between device ID and the keyword.

PUK The SIM card is locked (PUK code).
Set the SIM card to SIM-slot that is in the side of the modem, so that
circuit of the SIM-card is facing towards the sticker that is on the top of
the modem. Press the SIM-card until the slot snaps and card is properly
attached to slot. The SIM-card can be removed by using a at object such
as a screwdriver with at-head.
To be able to use the SMS-connection, the PIN code has to be installed in
the controller. Note. The controller is given the same PIN as that of the SIM
card. The SIM card’s PIN query must be on.

There are two alternative ways to set the Ouex M BA device IP ad-
dress and network settings:
1. IP address is retrieved via DHCP function. This requires that
DHCP service is in use in the network and network cables have
been connected.
2. IP address is set manually.
1. Request correct network settings (IP address, Gateway ad-
dress, Subnet mask, Nameserver address) from the network
administrator.
2. Go to “System settings” -> “Network settings” -> “DHCP” and
press OK.
3. Select ”O” and press OK to accept selection.
4. Enter all network settings (IP address, Gateway address, Subnet
mask, Nameserver address) provided by the network adminis-
trator.
5. Select ”Update network settings” .
System settings > Network settings (M-LINK)
The Ouman Access service (M-LINK device) can be purchased from
Ouman. It oers a secured connection to automation equipment
using an existing internet connection. If an internet connection is
not available, it is possible to use some 3G/4G modem, for example,
to establish a ready-to-use connection to the subject.
1. Go to DHCP and press OK.
2. Select ”On” and press OK to accept selection.
3. Select ”Update network settings” and press OK to accept se-
lection.*
4. Wait approximately one minute.
5. The network settings are now assigned to Ouex M BA by
DHCP server (new settings should appear automatically in the
user interface)
Otherwise check the network connections and ensure that
DHCP-server is available in the network.
Setting the IP address via DHCP function:
Setting the IP address manually:
1.3 Network settings (M-Link)
If you want to connect the Ouex M BA unit to an Ethernet net-
work, you will need an M-LINK adapter (additional equipment).
M-Link is connected to COM3 port (RJ45) located in the side of
the controller. The maximum length of the RJ45 ethernet cable
between Ouex M BA and M-Link is 10m and all 4 pairs must be
connected. If you have changed your network settings, select
”Update Network Settings”.

Modbus TCP/IP port (internal registers):
Port number 502 is reserved for communication of Ouex M BA
device. Information of Modbus registers of Ouex M BA device are
read and written through this port.
Max connections:
It is possible to decrease server load by changing this setting that
denes the maximum number of simultaneous connections from
dierent IP addresses to the server.
Idle timeout:
This setting denes the time after which the server closes an inac-
tive connection.
Allowed address:
It is possible to improve the information security of the system by
taking permitted connection address into use. If the value is 0.0.0.0,
connections to the server are permitted from any IP address. If
you dene one permitted connection address, connections to the
server are not permitted from any other IP address.
Function active:
This selection either enables or disables the Modbus/TCP commu-
nication.
Modbus TCP/IP gateway ->Modbus 1 port:
It is possible to connect a Modbus/RTU bus to Ouex M BA control-
ler. The bus has its own port address that is used to communicate
with bus devices via Modbus/TCP interface. Port 1 setting denes
the TCP/IP port that functions as a gateway to Modbus RTU-bus.
System settings > Network settings (M-LINK)->Modbus TCP/IP
If the Ouman Access is taken into use, the sent SNMP alarm
message will include the Access IP-address. In this case, Access
IP address must be entered as local IP-address in Ounet.
SNMP:
SNMP function can be used to send notications about alarms
activating, inactivating and being acknowledged via SNMP protocol
to a desired server.
IP address:
The IP address of the target server to which messages are sent.
Ounet IP address is a default.
Active:
This selection either enables or disables the entire SNMP function.

Ouex M BA device can be a master device in two Modbus RTU. It
is shown in the rst line in which the bus Ouex M BA is the master
device. All the devices in the same bus should be set to the same
setting value of the baud rate, data bits, stopbits and parity. If a de-
vice is unstable on the bus, it may be possible to get the bus trac
