Connecting the sensors
1-Wire / 1-Wire UNI (RJ11)
Connect the sensor before powering up the Poseidon –the
connector must click in.
Maximum total distance on each active port is 60m.
Sensors can be daisy-chained.
Sensors can be also connected using a star topology with the T-
Box (TBox2) hub.
If you change the sensor topology, the sensors must be auto-detected again. (Web
interface > Flash Setup > Sensor Setup > Autodetect Sensors)

Industrial Bus sensors (RS-485)
Industrial bus for connecting sensors over long distances
Connect the sensors before powering up the unit.
Sensors can be daisy-chained, or connected to a virtual star using
the “S-Hub” unit.
Terminate the RS485 line with a 120 Ω to 470 Ω terminator. Some
sensors contain a built-in terminator, controlled with a jumper or
a DIP switch. See the sensor manual.
Check or set the sensor address. Each sensor on the RS-485 bus must have a unique
address. The address (ID) is expressed as a letter (A..Z / a..z) or a number (65..122). The
numbers correspond to the ASCII codes of the letters, A=65, Z=90, a=97, z=122.
For details about address configuration, see the sensor manual.
If you change installed sensors, the sensors must be auto-detected again.
(Web interface > Flash Setup > Sensor Setup > Autodetect Sensors)
Sensors are shipped with non-conflicting addresses whenever possible. The preconfigured address
is always written on the label.
Note: A particular sensor is identified by its RS-485 address. Sensors with the same
address can be swapped without the need for a new detection.

Common features of the Poseidon product line
Displayed readings
The Poseidon unit displays current readings from all connected sensors.
Dry contact inputs are scanned approximately every 200ms.
Values from all sensors on both buses (RS-485 and 1W bus) are read in a single loop that
repeats once per second; however, the actual time needed to read the sensors may vary
from 1 to 30 seconds.
All values are in the “integer/10” format, range is ±999.9.
A value of 999.9 is out of range for all supported sensors and indicates that the sensor was
not found.
If you have disconnected or replaced a sensor, run sensor autodetection, or remove
the sensor from the list.
When the Poseidon unit is overloaded with network requests (as is sometimes the
case, for example, with our public online demo), -999.9 can sometimes appear even
though the sensor works properly. This is due to limited computing performance of the
unit. Try to reduce the number of concurrent network requests.
Units are assigned to values automatically according to the detected sensor type. Supported
units include:
Temperature: °C, °K, °F
(please note that Safe Range thresholds can be set in °C only)
Humidity: %RH
Voltage: V, current: A or mA
Other units: %, ...
Input / sensor in alarm state
Alarm state can be set independently for every input (contact) / sensor.
For a sensor, “Alarm” occurs whenever the reading is outside of the specified Safe Range,
as long as alarm alerting is enabled for at least one notification method (SNMP / Email &
SMS).
Response to a sensor being disconnected
-999.9 is displayed
The value evaluates as an “Alarm” (reading out of the specified Safe Range). If alarm
alerting is enabled for the given sensor, e-mail or SNMP trap is sent.
•For more information about data formats, identification of variables, and the
SDK, see the detailed Poseidon family manual.

Calibration
Each sensor can be calibrated by specifying a linear offset. The calibration value can be
written over XML. To set the calibration, use the Calibrator utility (download section on
the Poseidon 2250 page) or EX104 in the HWg-SDK (a menu invoked by a right-click).
Calibration value = +3 →sensor measures 0.5°C → Poseidon shows +3.5°C
Calibration value = -3 →sensor measures 0.5°C → Poseidon shows -2.5°C
Calibration value = -10 →sensor measures 27% RH → Poseidon shows 17% RH

7 / 105
Sensor hysteresis
The Hysteresis setting defines a tolerance band for alarm alerts. This feature prevents multiple
alarm alerts if the reading oscillates around the specified threshold. See the graph for an
explanation.
Without a hysteresis of 5°C, the alarm raised at point 8 would end at point 9. With the hysteresis
function, the alarm continues until the temperature rises above the tolerance band (point 10), that is,
5°C + (-15°C) = -10°C.
Hysteresis = 5°C: The unit sends 3 e-mails (SMS)
Alarm at points 0..4, 8..10, 12 and beyond
No hysteresis (0°C): The unit sends 8 e-mails (SMS)
Alarm at points 0..1, 2..3, 8..9, 12..13, 14 and beyond

Supported interfaces
Individual Poseidon models support several hardware interfaces for connecting the sensors. A brief
description follows. For more details, see the technical specifications of the interfaces.
Binary inputs (Dry Contact inputs)
Digital inputs for connecting two-state sensors. Dry Contact means a
direct connection of a volt-free contact. The input signals one of two
states –“On”/“Off” (or “Open”/“Closed”), which can be further
interpreted by Poseidon as “Normal”/“Alarm”.
Outputs and relays
Poseidon supports digital outputs. These can either be controlled over the WWW interface
(or SNMP, Modbus/TCP, XML), or used to indicate an alarm.
There are two types of outputs:
- Double-throw relay contact (Poseidon 3268)
- Voltage output to control an external relay (Poseidon 2250)
Sensors can be connected over two bus types:
1-Wire bus
Digital RJ11 bus, designed to connect several sensors over
short wiring. The bus carries power and a single data wire. The
bus is not suitable for environments with EMC interference.
Sensors have factory-assigned unique addresses which are
detected automatically as the sensor IDs.
Industrial bus (RS-485 supports up to 31 sensors, up to 1000m)
For convenience and ease of use, TP cables and RJ45
modular jacks are used to wire the RS485 industrial bus.
The RS-485 bus uses the blue pair of wires (pins 4 and 5),
labeled A and B. The brown pair (pins 7, 8) carries 12V to
power the sensors.
If you use the S-Hub unit and the B-Cable module, the green
pair of wires (pins 3, 6) is used for the return RS-485
connection. This wire pair is not connected at the Poseidon 2250 unit.
Sensor addresses are set by the configuration protocol or by jumpers, and are
detected as sensor IDs ranging from 48 to 127.

Detailed interface description
Power connector
The usual DC plug –2,5mm coaxial barrel connector –is
used to connect the power. Negative terminal is connected
to the outer body of the plug.
Ethernet
Ethernet network connects via the standard RJ45 jack next to the power
connector. Use a Twisted Pair (TP) patch cable to connect to a switch, or a
cross-over cable to connect directly to a PC.
The device has a 10 Mbps Ethernet interface => it only works in 10 Mbps or 10/100 Mbps networks.
Note: The device cannot be directly connected to a 100 Mbps-only network. If you need to
connect it to a 100 Mbps (or faster) network, use a 10/100 Mbps Ethernet switch.
MAC address
MAC address is a unique number identifying the device. It is printed on the label at the bottom side of
the unit. It consists of six hexadecimal number pairs, the first three pairs are always 00:0A:59.
With the MAC address, you can distinguish individual devices in the UDP setup utility when assigning
IP addresses.
Configuration with DIP switches
DIP switches control the following functions.
If you change the settings, it is recommended to reset
the device by disconnecting and reconnecting the
power.
Factory default configuration is:
DIP1=Off, DIP2=Off, DIP3=Off, DIP4=Off.

DB9M - RS-232
The interface is intended for setting up the device (RS-232
Setup when DIP1=ON) and for updating the firmware.
The DTR and RTS outputs can be controlled from the Flash
setup interface, tied to an alarm state, or controlled over the
network.
Voltages corresponding to logic levels on these outputs:
RTS
0(Off) = -10V (-12..-6V)
1(On) = +10V (6..12V)
DTR
0(Off) = 0V
1(On) = +10V (6..12V)
States of outputs after device restart: RTS = Off (-10V), DTR = Off (0V).
Using the RTS and DTR outputs
Port 3 complies with the RS-232 specification. If needed, the P1250 RC converter (designed for
connecting two 12VDC rated relays to Poseidon 2250 over RS-232) can be used to connect two
external relays. The converter applies approximately 10V to the relay coil, making it possible to
control 9VDC or 12VDC rated relays.
P1250 RC (Relay Cable) - Ordering No. 600 244
Relay coils connect directly to a small terminal block. Polarity is shown on
the label, closed state is indicated by a LED lighting up.

RJ11 –1-Wire or 1W sensors
The digital bus from Dallas Semiconductor company, each sensor
has unique ID.
We recommend to keep the total wiring length under 60m, although
functionality has been achieved over tens to hundreds of meters in
experimental settings.
If the wiring connected to a single connector of the Poseidon unit is
longer than approximately 80m, we cannot guarantee error-free
operation, as it greatly depends on the actual wiring implementation,
topology and environment.
Active / Passive 1W port
Active port is RJ11 connector on the Poseidon device. It guarantees full length of wiring and power
for defined quantity of 1-Wire or 1-Wire UNI sensors.
When you move the sensor from one active port to other one, the sensors seems to be disconnected.
You have to run sensors auto-detection again.
Passive port is RJ11 connector on T-Hub splitter or on the 1-Wire sensor in daisy-chain wiring.
It can’t guarantee full length and full power for all following sensors.
The power issue can be solved with using the 1-Wire hub Power.
1-Wire UNI (RJ11)
1-Wire UNI is software extension of the 1-Wire bus.
1-Wire UNI sensors:
oLight sensor
o4-20mA sensor
o0-60V (-48V DC) sensor
o0-30A AC sensor
o>>Various other sensors
Maximum wiring length : 60 meters of total length per active RJ11 port
Note: Distance can be limited with some 1-Wire UNI sensors or with more RJ11 male-female
connectors.
Sensor power supply: 5V/20 mA from RJ11 connector
(can be boosted by "1-Wire hub Power")
Other parameters or 1-Wire UNI are identical with 1-Wire bus.

RJ45 –Industrial Bus (RS-485)
The RS-485 bus can be used to connect up to 31 sensors over up to
1000m, even in industrial environments. For convenience and ease of
use, TP cables and RJ45 modular jacks are used to wire the RS485
industrial bus.
The RS-485 bus uses the blue pair of wires (pins 4 and 5), labeled A
and B. The brown pair (pins 7, 8) is used to supply 12V to power the
sensors.
If you use the S-Hub unit and the B-Cable module, the green pair of
wires (pins 3, 6) is used for the return RS-485 connection. The green
pair of wires is not connected at the Poseidon 2250 unit.
Maximum wiring length: Up to 1000m in total
Supported sensors: Temperature, humidity, current, voltage, and more (see the overview
of available sensors)
Number of sensors on the RS-485 bus: Up to 31 physical
sensors
Power: 12V/120 mA available at the RJ45 jack. Power supplied by
the bus is sufficient for up to 3 external sensors, an S-Hub can be
added to power more sensors
Communication cable: UTP, in some cases 4-wire phone cable
Alarm settings: Checking the reading against its Safe Range,
configuration in Poseidon Flash setup
Polling period: 800 ms to 10 s (depending on the number of sensors, 10 seconds for 41

Termination
The RS-485 bus must be terminated at its end. The following options are available:
Internal jumper on certain sensors (jumper named TERM or TERMINATOR) –for example
in Temp-485 or HTemp-485
B-Cable adapter with “LAST” configuration selected using the switches
External resistor to terminate the bus at the “last” sensor, if the sensor has no jumpers or
DIP switches (Temp-485-Pt100). Connect the resistor between the A and B terminals of the
last sensor.
The resistance of this resistor should be 120Ω. For short wirings, 470Ω can be used to
reduce the current consumption of the sensors.
Note: A disadvantage is that it is necessary to have a wiring topology with a single
beginning and a single, terminated end, as opposed to the popular star topology with
a single interconnection point.
Special accessories for the RS-485 bus
B-Cable - RJ45 / 4-wire connection
The B-Cable module is an adapter that converts a RJ45 jack
connection to a block of 4 terminals A,B,+,–.
Some of the available RS-485 sensors already have a RJ45
jack; however, some only have 4 terminals labeled A,B,+,- .
Such sensors can be connected Poseidon 2250 or to an S-Hub
using either a TP cable (4 or 6 wires) or the B-Cable module.
The 4-wire connection
length should not exceed
20cm.
Sensor position on the RS-
485 bus (MIDDLE / LAST)
is selected with jumpers;
see the picture for details.
