Power Supply
External power supply
The permissible power range is 5-22V. The average consumption of the device is 1.5-2 watts. But since the GSM module consumes up to 8W impulsively, it is recommended to use power supplies with a power of at least 10W.
Power plug for standard jack 5.5x2.1 mm located on the rear panel. Power can also be supplied to the corresponding pins (see Pinout below) of the RJ45 connector on the rear panel.
Power over Ethernet
Supports Power over Ethernet (Passive PoE) via RJ45 connector on the front panel. Supports the standard voltage of 12V and 15V. See Power over Ethernet.
Battery
The Wiren Board NETMON-1 can be equipped with one or two Li-Ion (Li-Pol) batteries with a maximum voltage of 4.2 V. When the power is connected, the battery is charged with a current of up to 0.5 A.
Protection against charging at low temperatures and overheating.
GSM/GPRS-modem
Wiren Board NETMON-1 comes with 2G (GPRS) modem that supports GPRS, CSD, sending and receiving SMS.
The GSM antenna is connected to the SMA connector on the back of the controller. If the GSM signal is weak, it is recommended to use a remote antenna and place it away from the controller.
USB port
Wiren Board NETMON-1 has one USB port (Host, type A) inside the case. The port is designed to connect Wi-Fi sticks, 3G modems, etc.
External load switching
Back panel
thumb | 500px | Inputs/outputs for 220V control and GSM antenna connector
The Wiren Board NETMON-1 is equipped with two power switching groups on the rear panel.
Each group consists of an IEC-320-C14 plug (input) and an IEC-320-C13 socket (output). The input and output are connected via a relay. The relay is normally closed (i.e. when WB NETMON-1 is off, the sockets are on).
Rated relay current: 16A/250VAC. The relay opens only one (phase) wire. It is recommended to use outputs for switching resistive load up to 10A.
On request, a configuration is available to use a common input to both outputs.
Front panel
thumb | 300px | Front panel relay outputs
There are four groups of relay outputs, output on the connector terminals, on the front panel of the Wiren Board NETMON-1.
Each relay is switchable, i.e. contacts NO (normally open), NC (normally closed), COM (common) are derived.
Rated relay current: 10A@240VAC (resistive load).
It is recommended to use outputs for switching resistive load up to 5A @ 240V AC.
Serial ports
The Wiren Board NETMON-1 is equipped with two half-duplex RS-485 ports and two RS-232 ports (RX/TX only).
Both RS-485 ports and one RS-232 port are output to RJ45 connectors on the front panel, one RS-232 port is output to RJ45 connector on the back panel.
Linux devices:
- /dev/ttyNSC0 - RS-485 on I8 connector
- /dev/ttyNSC1 - RS-485 on I6 connector
- /dev/ttyNSC2 - RS-232 on I4 connector
- /dev/ttyNSC3 - RS-232 on rear panel connector
See also RS-485 for information on working with RS-485 and connecting peripherals.
Debug console
Debug console (debug UART) is output to connector I2 (see below), as well as to the comb inside the case. The port has 3.3 V levels and requires a special USB-UART or RS232-UART adapter to connect to the computer.
For details on working with the debug console, see Debug UART.

Standard wiring diagrams
Low voltage load control
12/24V relays, LEDs, fans, signal lights, etc.
The low-voltage load can be controlled by four relays on the front panel.
Electric contactors with control voltage of 220 V
Connect the contactor control coil via the relay on the front panel.
Relay in Wiren Board NETMON-1 contains no protective damping chains, aware when connecting inductive loads.
Sensors with analog voltage output
Connect the ground of the device to the GND terminal, or connect to a common ground bus. The sensor output is connected to analog inputs in A1-A7 connectors.
Датчики с аналоговым токовым выходом
Специальных токовых входов в Wiren Board NETMON-1 нет, но можно, используя резистор 100-300Ом, ток преобразовать в напряжение и подключить как в предыдущем пункте.
Датчики с резистивным выходом
С помощью внешнего резистора и опорного напряжения нужно собрать делитель, чтобы получить выход напряжения (см. предыдущие пункты). В качестве опорного напряжения можно использовать выход +5V с контактов 7-8 разъёма а1, или 1-2 разъёма и2.
Датчики удобно подключать к разъёму "а1", имеющему два входа АЦП и опорные напряжения .
Аналоговые датчики с внешним питанием
Аналоговые датчики с внешним питанием, такие как электрохимические датчики серии MQ-xxx, датчики влажности HIH-4000 и т.д. также удобно подключать к разъёму "а1", имеющему входы АЦП и опорные напряжения.
Датчики/счетчики с импульсными выходами
Такие устройства формируют сигнал, замыкая подходящие к ним два провода. Подключите один провод к контакту "Isolated GND". Второй провод подключите к одному из соответствующему контакту (discrete input) разъёмов и1,и3,и5,и7,и9.
Некоторые счетчики имеют импульсный выход на оптроне, тогда два провода имеют полярность - "плюс" и "минус". В таком случае минус подключается к "Isolated GND", "плюс" к "discrete input".
Подключение к 1-Wire сети
Для подключения 1-wire используется разъём и2.
Землю сети подключите к контактам GND (7-8@и2 и др.) или общей земляной шине. Линию данных к контакту "1-Wire" ( 4@и2) . Линию питания к контакту "5V" (1-2@и2) (внутренний источник питания). Допускается использовать внешние источники питания шины 1-Wire.
При использовании пассивного питания, контакт питания каждого датчика соединяется с земляным проводом. В этом случае, шина прокладывается двумя проводами, подключаемыми соответственно к "1-Wire" и "GND".
Подключение к сети RS-485
Смотрите RS-485.
В Wiren Board NETMON-1 два порта RS-485 на разъёмах "и6" и "и8".
Линии А В подключаются к клеммам А и В соответственно.
Датчик температуры и влажности
Wiren Board NETMON-1 может комплектоваться встроенным датчиком температуры и влажности. Подробнее см. Датчик SHT1x.
