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

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.
