parameters, resetting of MAC-address and other Ethernet settings;
 Protection of access (password for setting mode, filter of IP-address for setting or connection to Modbus
network, connection only to the selected server with automatic login, password for control via SMS);
 Different modes of data interchange via MODBUS network (RTU or ASCII, with checking of parity for even-
odds or without checking, wide range of transmitting rate, adjustable delay);
 programming the collection of data, events, and action for events (see Appendix С);
 Service functions (real time clock, firmware updating option).

1.2. Controls, overall and mounting dimensions

1.2.1. Overall and mounting dimensions of EM-481 are shown in Fig. 1.1.
1.2.2. Controls are shown in Fig. 1.2.
8 – "485" is on when waiting a respond from the device in Modbus network; it is blinking while data exchanging via
Modbus network;
9 – "R" reset button (is located under the housing, designed to restart the device or by thin non-conducting current subject).

1.3. Operation conditions

The device is intended for operation in the following conditions:
– Ambient temperature: from minus 35 to +55 °С;
– Atmospheric pressure: from 84 to 106.7 kPa;
– Relative humidity (at temperature of +25 °С): 30 ... 80 %.
ATTENTION! The device is not intended for operation in the following conditions:
– Significant vibration and shocks;
– High humidity;
– Aggressive environment with content in the air of acids, alkalis, etc., as well as severe contaminations
(grease, oil, dust, etc.).

1 – "PWR" LED is on when there is supply voltage;
2 – "LAN" LED is on when connected to Ethernet network, it blinks
while the data exchanging via the network;
3 – The display serves to display the state of the device, the
connections, the load of the communication interfaces, and showing of
warnings about detected faults;
4 – "GSM" LED is blinking every 3 sec. when there is connection via GSM
network or UMTS, it is blinking 3 times per second while data exchanging
via GPRS or HSPA;
5 – "AL" LED warns about the registration of the fault in the course by
analysis of the received data;
6 – "SD" is on when there is a memory card in a special slot, it is
blinking while the data exchanging to SD-card;
7 – "SRV" is on when there is a connection with a server for data
collation, it is blinking while data exchanging with the server;
