[USS] Sockets and Indication Elements

POWER LED

A POWER LED (see picture 1 and picture 2), when turned on, means a device works.

IO Lines Connection Terminals

Picture 1 – A terminal block for connecting IO lines (UniPing server solution v3/SMS device)

Picture 2 – A terminal block for connecting IO lines (UniPing server solution v3 device)

DISCRETE IO terminal block is used to connect universal IO lines.  

There are eight IO lines in a block. For each line, there are two contacts: IO and GND. To make connecting sensors convenient, there are terminals +5 V and +12 V in a DISCRETE IO block. A maximum summed current on +5V and +12V terminals is 200mA, it is limited by a self-resetting fuse. To recover a terminal operation after a reboot, there is a need to deenergize a device completely for 30 minutes.

Electrical specifications of IO lines in the "output" mode:

Voltage of the logic "1":  4V, maximal current is: 0.3 mA

Voltage of the logic "0":  0,1V, maximal current is: 0.8 A

Electrical specifications of IO lines in the "input" mode:

Voltage of the logic "1":  >2.1V

Voltage of the logic "0":  <0,9V

It is possible to plug relay coils to UniPing Server Solution v3/SMS IO lines directly. A voltage of triggering a relay should be either 12 V or 5 V, and a triggering current - no more than 200mA. Control relay contacts are connected to an IO terminal and to the terminal +12 V or 12 V relay or a +5 V terminal for a 5 V relay. A corresponding IO line should be set to an output mode. When connecting several relays, there is a need to take into consideration that their summed maximum triggering current should not exceed 200mA.

IO STATE LEDs

IO STATE LEDs (see picture 1 and picture 2) signal about a status of the first four IO lines. When a LED is turned on, a corresponding IO line is in a status logic 1, and a turned off LED means a logic status 0.

Thermo / IR Terminals

Picture 4 – Terminals «Thermo / IR» (UniPing server solution v3 device)

A THERMO/IR terminal block is used to plug temperature sensors and an IR-transceiver. To make plugging sensors convenient, connecting terminals are output to a front panel twice. Temperature sensors can be plugged into a left terminal block as well as into a right one. An IR transceiver is plugged in parallel to temperature sensors into the same terminals.

Smoke Terminals

Picture 6 – Terminals «Smoke» (UniPing server solution v3 device)

A SMOKE terminal block is used to plug in a smoke sensor.

1W Sockets

Picture 8 «1W» sockets (UniPing server solution v3 device)

1W sockets are used to plug in sensors of a model line 1-Wire, that are built using a 1Wire technology. To make sensors plugin more convenient, there are four sockets on a body of a device. It is possible to plug in more than four sensors of a model line 1-Wire, using splitters and  extenders.

RS232 / RS485 Sockets

Picture 9 «RS232 / RS485» sockets (UniPing server solution v3/SMS device)

Picture 10 «RS485» sockets (UniPing server solution v3 device)

RS232/RS485 socket is used to plug in RS232/RS485 devices. A port RS232/RS485 can work in the mode of converting interfaces RS232/RS485 – Ethernet via TCP protocol. 

Important! Ports RS232 and RS485 use one bus inside a device. It is prohibited to plug in devices to the ports RS232 and RS485 simultaneously.

 There is no «RS232» socket in a UniPing server solution v3 device.

Relay Socket (PWR)

Picture 12 – Socket «PWR» (UniPing server solution v3 device)

Contacts of a relay, built into a body of a device, are output normally opened and normally closed. A relay can be used for managing a Reset button of a computer as well as for connecting an Alarm АС-10.

Electrical parameters of power management channel RELAY are as follows:

  • The maximum permissible voltage on the relay contacts is 50V;
  • The maximum allowable current through the relay contacts is 2А 

LAN Sockets

Picture 13 – LAN sockets (UniPing server solution v3/SMS device)

Picture 14 – LAN sockets (UniPing server solution v3 device)

Ethernet 10/100 BASE-T ports form together a two-port Ethernet switch. One port is used to connect to a network, and the other one - to connect an additional equipment (another NetPing device, an administrator's laptop, etc.), which gives a possibility not to install an additional switch on a remote land. These ports are equal, and any of them can be used to connect to a network. 

Important! Connecting both ports to an Ethernet switch with turned off STP protocol will lead to creating a loop in an Ethernet segment.

Ethernet ports have two LEDs. The left one is CPU, and when it is lighting, it means a device is turned on. It blinks when packages are transferred to a network. The right one is Link, when it is lighting, it means having a link on this port. It blinks when receiving packages from a network.

GSM Sockets

Picture 15 – GSM modem sockets (UniPing server solution v3/SMS device)

GSM ANT socket is designed for plugging in an external antenna, which is included into a shipping kit. A SIM Card slot is designed for installing a SIM card.

Important! Before installing a SIM card into a device, disable PIN code verification on it, using an ordinary cell phone.

Reset Button

A Reset button is designed for resetting parameters to default values. To reset the parameters, press a Reset button with a sharp object and hold it during a device is turning on. 

Power Supply Inputs

There are two power supply inputs on a back panel. One of them is used to feed a device from an external power supply unit 5 V DC (1,5A). Another one is used to feed a device from an internal power supply unit 220 V AC.

Important! It is prohibited to power a device from two power sources (an external and an internal one) simultaneously. It can damage a device.
