SERInet is a converter from RS485 to Ethernet (TCP/IP). Converter is possible to be
supplied passive PoE thanks to the Ethernet data cable or by power supply on the
terminals.

Terminals connection

SERInet in variant „SERInet RJ“ has on the side two equal connectors RJ15 (another
variant is „SERInet ST“ with six pin screw terminals).

wires preparation:

Power supply

This unit has two power supply options, passive PoE or external supply on the terminals IN
9-32VDC. Consumption in both cases is 1,5W (supply current is in both cases dependent
on the connected voltage).

Passive PoE

Power supply is distributed together with the Ethernet to the ETH
connector. Power supply is inserted in the data cable using the
common passive PoE injector. Supply voltage can be in range 9­32V.

IN 9-32VDC DC power supply 9-32V to the terminal „IN 9-32VDC“

Serial line is galvanically separated from Ethernet network and has its power supply on the
terminals V+ and GND. Supply voltage can be in range 9-32V.

Protocol

Data are sent to the Ethernet network through the TCP/IP protocol.

Setup

Setup of the SERInet converter is done by web browser. To the address line input the IP
address of the converter. In the factory settings the address is 192.168.1.241
If the address is unknown the converter can be found using DALIconfig program which is
downloadable for free on the www.foxtron.eu

Default Ethernet settings in show in the following picture

General TCP settings

Device Name (for DHCP) SERInet name for DHCP server

Addressing Mode

Static –manual setup of the IP address

DHCP – automatic setup of the IP address using

TCP setup for incoming connection

Listen for incoming network
connections

turn on the possibility to connect to the SERInet
converter

Listening network port

number of port on which the SERInet waits on
connection

Timeout and disconnect after this
many seconds of inactivity

The inactive time after which the SERInet terminates
the connection. Setting the parameter to 0 is this
function switched off.

Allow new connection if the existing
connection has been idle for this
many seconds

The inactive time after which is allowed to start new
connection. Setting the parameter to 0 is this
function switched off.

TCP setup for outgoing connection

Make outgoing connections

Never – SERInet converter does not create
connections

On power-up – SERInet converter creates
connection after connecting power supply.

If serial data received – SERInet converter creates
connection if it receives data on the serial line

Connect on network port

port number on which the SERInet creates
connection

Connect/Send to this address

IP address on which the SERInet creates the
connection

Timeout and disconnect after this
many seconds of inactivity

The inactive time after which the SERInet terminates
connection it created. Setting the parameter to 0 is
this function switched off.

Retry failed outgoing connections The time after which the SERInet repeats the

number of characters which will be send in one
message (maximum 128) – data will be also send if
the set time passed or the set character come

0 waits forever

the time after which the received characters are
sent.
0 signs that the data will not be sent dependently on
the time.

Flush TCP/UDP frame when this
character is received (Enter NA to
disable)

Decimal character value (ASCII) after which
reception will be sent. If the „NA“ is input no
character is selected. For example CR (carriage
return) is 13.

By pressing the button „Submit New Settings“ the selected settings are saved.

Serial line basic setup is shown in the following picture.

Data Baud Rate

Communication speed choice. Selection is possible from
commonly used speeds. Choice „Custom“ sets the speed
defined by user.

Custom Baud Rate

Communication speed chosen by user. Used in the case that in
„Data Baud Rate“ is set „Custom“

Data Bits number of data bits

Data Parity

None – no parity used

Odd – used odd parity

Even – used even parity

Stop Bits number of stop bits

Password setup is shown in the following picture. Password into the web configuration is
not required by default.

For change of password fill the User Name and twice new password. In the case that you
do not want to use password leave the password fields blank. By pressing the button
„Submit New Settings“ you save new password.

Power Express (PEX)

In the case of using with Power Express system (PEX) it is suitable to insert
the reduction on the RJ15 connector which is used for PEX bus by default.

Recommended setup „CUSTOM PACKETIZATION“ for PEX bus.
