1 DESCRIPTION AND OPERATION
1.1 Function
АСМ-IP2.1 provides conversion of a digital communication interface into an analog
interface to ensure loud-speaking operative-process communication with subscriber
intercoms equipped with an analog interface.
ACM-IP2.1 is installed on the DIN-rail 35 mm wide in communication cabinets, racks
located in offices and control rooms.
АСМ-IP2.1 appearance is shown in Figure 2.
The housing is made of polyamide. The housing color under RAL is 7035.
Note — The manufacturer is entitled to change the overall appearance of the product
if this does not affect installation dimensions and operation.
ACM-IP2.1 contains embedded software and configuration data stored in memory,
which allows it to communicate with other digital communication system users directly,
handle priority connections and manage communication and indication modes. An IP-
network based on standard network equipment is used to facilitate communication.
Within the digital intercom system, the ACM-IP2.1 provides the following functions:
−functions of subscriber device in loud-speaking systems under Armtel-IP and
SIP protocols providing reception and transmission of an analog signal
(amplifiers, integration of analog intercoms);
−control (commutation) of external actuating devices 48V (relay, lamp-type
signaling device);
−recording of voice messages from terminal devices into internal memory;
−playback of voice messages recorded in the internal memory of terminal units;
−providing of calls priorities, set during configuration of the subscriber units, via
SIP and Armtel-IP protocols.
Configuration of АСМ-IP2 is performed from the administrator's PC, on which
the "IPN2 Configuration Software" RU.RMLT.00041-01 should be installed.
Figure 1 shows several alternatives of АСМ-IP2 usage.

Figure 2 shows connectors:
1– Line connector for connection of discrete lines (control lines), software
configurable or as input for connection, for example, direct call key of the
terminal units or as output (for load connection);
12 – Eth connector RJ-45 8P8C for connection to Ethernet network (including PoE
power supply).
Indicators on Eth connectors:
1) green – ON when there is physical connection with Ethernet network,
blinking when network interface is active (receiving or transmitting of
data packages);
2) orange – ON when the unit is powered from the PoE source;
When supplied from an external power supply, LEDs become green and orange
meaning that there is power supply and Ethernet connection.
13 – connector for connection to the analog line and transformer central point
control line.
14 – connector for connection of external DC power supply 48 W. In case of no PoE,
it is used as an input for power supply connection. When ACM-IP2.1 is supplied
from PoE, it is used as an output for supplying external devices connected to
this ACM-IP2.1 (for example, an analog intercom). The total power consumption
of ACM-IP2.1 and external device in this case must not exceed the maximum
permitted loading power according to PoE class. Connector pins are also used
for Line control lines. + pin is used as a common wire to connect buttons or dry
contacts to lines; – pin is used to connect to loading lines such as actuation
relays.
Figure 2 shows controls and indicators:
5, 6 – Offset lines 5…8 and Offset lines 1…4 on/off switches for counter calls on
control lines 5-8 and 1-4, respectively.
The switch controls switching of reference voltage of Line 1 — Line 8 (OFFSET).
Reference voltage must be corrected when arranging a connection between
centrals along analog lines to implement the priority function in case of a
counter call.

switch must be on to transmit a control signal by activating the device via the
middle point, for example, if ACM-IP2.1 is used together with an analog
intercom or controlled amplifier. For all other devices, the switch is
recommended to be turned off.

10 – DEF button to reset to factory settings. If the button is kept pressed with ACM-
IP2.1 pressed, network settings and user data will be reset to default settings. To
reset, press and hold the button for seven second, then wait until ACM-IP2.1
reboots.
11 – RES reset button. To reset ACM-IP2.1, shortly press and depress the button,
and wait until rebooting.

In order to ensure fire safety, observe the following rules:
−before connecting the product to the power supply, make sure the power and
communication cables are properly insulated;
−protect power and communication cables from damage.
2.3 Preparation for use
Preparation of the ACM-IP2.1 for use shall be carried out by the manufacturer’s
representatives, or personnel trained to operate Armtel LLC products. The main preparation
of the product for use is carried out during installation and connection.
ACM-IP2.1 is prepared for operation in several steps:
−removing ACM-IP2.1 from the shipping container and/or consumer package;
−checking the scope of supply of ACM-IP2.1 according to product passport;
−visual inspection of the device for damage (cracks, dents, chips, etc). During
visual inspection, pay attention to the integrity of the product, condition of
connectors, buttons, switches (all buttons/switches shall be easy to press and

−connect the product to a PC, on which RU.RMLT.00041-01 IPN2 System
Configuration Software Tool is installed, and to the power supply, set the IP
address for operation on a shared network or turn on the DHCP. To do it, the
connection to a PC via an IP network can be used. The product may be powered
by a PoE plus injector or a 48 VDC external power supply.
Note — During manufacturing, each ACM-IP2.1 is assigned with the identical IP-
address by default: 192.168.100.10, subnet mask: 255.255.255.0. If DHCP is turned on, the
product is automatically assigned an IP address when connecting to a shared network.
ATTENTION! DEVICES WITH THE SAME IP ADDRESSES ARE NOT ALLOWED ON
THE SAME NETWORK. THE IP ADDRESS MUST BE SET BEFORE CONNECTING TO
THE SHARED NETWORK.
−enter a record on the set IP address or DHCP in the “Special notes” section
of the product passport;
−disconnect from power supply and PC;
−install and connect the ACM-IP2.1 at the operating site (see 2.4).

2.4.2 Connection
2.4.2.1 АСМ-IP2.1 can be connected:
а) via 100BaseT Ethernet interface. The on-site connection is carried out using
multi-wire UTP type cable, crimped with RJ-45 plugs, which is connected to Eth
RJ-45 connector (pin assignment is given in Table A.1). On the other side, the
cable is connected to a network unit with PoE plus injector function.
б) via –IN –OUT 0 V 0 V connector (pin assignment of the connector is given in
Table А.1) by a cable with maximum wire cross-section of 28 to 12 (AWG)
(maximum cross-section of crimped wire is 3.3 mm2) crimped by a connector
from the scope of supply. On the other end, the cable is connected to the
external 48 VDC power supply min. 15 W.
2.4.2.2 A terminal device is connected to the Line connector (pin assignment of the
connector is given in Table А.1) by a cable with maximum wire cross-section of 28 to 16
(AWG) (maximum cross-section of crimped wire is 0.5 to 1.5 mm2) crimped by a connector
from the scope of supply.
2.4.2.3 A B CP +V (pin assignment of the connector is given in Table А.1) is connected
to an analog line and transformer central point control lines. Connection is done using a
cable 28 to 16 (AWG) in cross-section (cross-section of crimped wire is 0.5 to 1.5 mm2)
crimped by a connector from the scope of supply. Terminal devices are connected on the
other side of the cable.
2.4.2.4 The availability of reverse polarity protection at the ACM-IP2.1 input prevents
damage to the device, and so the performance of the device is not affected when reverse
polarity supply voltage is applied across contacts 1, 3 and 4 of -IN –OUT 0 V 0 V connector.
Contact 2 (-OUT) is not protected against reverse polarity and is an output.
2.4.2.5 Connection examples are given in Appendix B.
2.4.2.6 Connection cables are not included in the scope of supply.
