Indicator meanings
The controller ESMB 3.0 has three light indication signals. Controller’s state can be monitored by
watching the LED signals on its front panel. Their meanings are explained in the table below. Two of them are made
to indicate meter interfaces (CL1, CL2), another indicates turned on power and communication with client device (for
example, PC).

The controller is connected to an alternate voltage power supply, which nominal voltage is from 90 V
to 264 V. Connection scheme is illustrated in figure 3.3.
fig. 3.3 ESMB 3.1 connection to a power supply scheme
It is very important to make sure if the right wiring pins are being used while connecting the controller to
the power supply. If the power supply is connected not in to correct outputs controller will be damaged.

ESMB 3.1
A two wired cable for the controller‘s power supply, has to be connected to a switch nearby, which meets
the following requirements:
• switch‘s nominal voltage and current has to meet the controllers nominal voltage and current;
• switch must be mounted close to the controller and easily reached to the operator;
• switch must be marked, as the controller‘s cut-off device;
• switch‘s pin separation must be no less than 3 mm.
Connecting the controller to PC through RS232 interface
The controller is connected to PC using RS232 interface, connection scheme is showed at figure 3.4.
It is necessary to notice, that the controller’s RS232 interface output TX (Transmitter) sends data, while RX (Receiver)
receives. The controller’s TX output is connected to the computer’s COM port by RX input, whereas the controller’s
RX output with COM port’s TX.

CL interfaces
Controller ESMB 3.1, depending on its modification, can have up to two 20 mA current loop interfaces
to which you can connect up to 10 meters, that is to say 5 meters for every current loop. Circuit of meters sequentially
connected to the controller‘s current loop should be closed. Meters connection to a single current loop is illustrated
in figure 3.5.

fig. 3.5 Meter connection to ESMB 3.1 through current loop interfaces
The maximum current loop interface conductor length can be up to 1000-2000m. However, the longer
the lines are, the slower data transfer speed is. If the conductor’s length is more than 100m, it is recommended to
set up an additional surge protection (type PROTEC 10). It is recommended to use a twisted-pair cable 2x0.5 or
2x0.64, also it can be shielded signal cable, for example LIYCY 2x0.5, J-Y(St)Y 1x2x0.6. If meters are connected
correctly into chain, the voltage on every meter’s current loop connectors has to be 3,5...4 V (when no data is being
transferred). The measured voltage on the controller’s CL outputs (9-10 or 11-12) has to be 3,5…4 V. If there is more
than one meter connected to the same current loop interface, the measured voltage has to be multiplied by the
quantity of connected meters. For example, if there are two meters connected to the controller’s CL outputs, the
voltage will be 7-8V, if three – 9-12V and so on.

RS485 interface
Physically you can connect up to 32 meters to this interface, so if the controller’s current loop is not
being used, you can connect up to 64 meters. Interface conductors cannot be longer than 1000 m. It is recommended
to use a twisted-pair cable 2x0.5 or 2x0.64, also it can be shielded signal cable, for example LIYCY 2x0.5, J-Y(St)Y
1x2x0.6. When connecting more than one meter to RS485 interface, RS485 network topology must be “lines”, but
not the “stars” or any other type, that is to say RS485 interface cable must go from one meter to another without long
ramifications. Meter connection to RS485 interface is showed in figure 4.7. IMPORTANT. It is necessary to observe
polarity! (“A” and “B”)

ESMB 3.1 parameterization menu
ESMB 3.1 can be configured through all inputs (Ethernet, COM) using the PC’s “HyperTerminal”.
Information about how to configure “HyperTerminal” software is explained in supplement 1. After the “HyperTerminal”
(further terminal) is configured, ESMB 3.1 menu can be opened by pressing the <Esc> button three times. Some
modifications might require entering the password to access the menu after pressing the <Esc> button. Menu window
is displayed in figure 4.1.
fig. 4.1 Main ESMB 3.1 menu window view
Symbol “-->” indicates menu item’s selection. By pressing <ENTER> button you can enter the selected
menu item. Menu item’s selection is controlled by pressing the arrow keys <↓> and <↑>. If user does not make any
changes for 60 seconds, the menu will close itself and display “Exit terminal mode” message. To exit from the menu,
select the menu item “EXIT”. Controller’s menu hierarchy and detailed menu item’s explanation are described in table

1 supplement HyperTerminal software configuration
“HyperTerminal” is software which can operate through TCP/IP and RS232in as well and it should be used for
controller’s ESMB 3.1 configuration (1 and 2 ex.) or other analog software, which allows connecting to the controller
through these interfaces, for example, telnet client for TCP/IP connection. If you are using Operating System
Windows 7 or later, the “HyperTerminal” software can be downloaded from this link:
http://downloads.elgsis.com/hyperterm.zip, extract the files from the downloaded archive to a single folder and run
the „hyperterm.exe“. COM interface settings for parameterization is independent from settings which are used
for data reading and must be set in this way: 4800 (2400, 9600, 19200 and etc., depending on the controller
interface’s speed) bits per second, parity - none, 8 data bits, 1 stop bit, flow control - none.
Please note, that using TCP/IP connection the controllers default data port is 502, but the configuration port is
23.
1 ex. Enter the new connection name
2 ex. Case a: If you are connecting through RS232in interface, select an interface to which ESMB 3.1 is connected and
continue configuration
Case b: If you are connecting through TCP/IP interface, enter your controller’s IP address and port (default “23”) and
skip next steps
