Getting Started

Flowire

1 Flowire Connection

The Flowire converter board must be connected to the

Flowire bus as shown in the picture below. The red

wires are the positive supply voltage and the black

wires are the ground.

The voltage on the Flowire bus can range from 20 to 48

VDC, and for convenience, the board is equipped with

two connections to the bus.

LPlease note that these two connections are equivalent.

For the rst unit on the bus, one connection can be

used to connect the power supply, while the other can

be used to connect to the actual bus. The power supply

may be connected at any point on the bus, i.e. it can

be connected to any of the Flowire converter boards on

the bus.

2 Ethernet Connection

Ethernet is connected via the RJ45 port. This supplies

10/100 Mbps Ethernet and power over spare-pair. The

power on the spare-pairs is the same voltage as the

one supplied to the converter board. Hence a voltage

of more than 39 volts must be applied to the converter

board in order to power STENTOFON IP stations

directly.

LDO NOT connect the RJ45 port to a PoE switch/injector

as this may damage the converter board!

LThe RJ45 port is NOT a PoE compatible output but DC

voltage on spare-pair which is present at all times. It

should NOT be connected to any equipment that may be

damaged by this voltage.

3 Indicators

The Flowire converter board is equipped with three

green LEDs. These LEDs indicate the status of the

power, the connection to Flowire, and whether data is

transmitted on Flowire or not.

LED2

LED1

LED3

LED1: This LED is lit when the board’s local power

supply is working and ready to power the board.

LED2: This LED is lit when the converter board

recognizes one or more boards on the Flowire network.

LED3: This LED ashes when the converter board

receives data from the Flowire network.

4 Quick Connect Button

The quick connect button (the only button on the

converter board) is only used when the converter board

is added to a new Flowire network. When the button

is pressed, the board will automatically connect to the

other devices in the same physical Flowire network.
