Industrial Bus sensors (RS-485)
Industrial bus for connecting sensors over longer 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, jumper- or DIP-controlled terminator. See
the sensor manual.
Check or set the sensor address. Each sensor on the RS-485 bus must have an 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 the sensor topology, 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 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.
•For details about connecting sensors, see the description of the interfaces.
•For more information about connecting sensors and wiring lengths, see the
detailed manual for the Poseidon line of products.

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 load.
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: %, etc...
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 / e-mail &
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, variable identification and the SDK,
see the detailed manual for Poseidon product line.

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
•For more information about data formats, variable identification and the SDK,
see the detailed manual for Poseidon product line.

Detailed device 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.
DIP SWITCH configuration
+ DIP1 –RS-232 Setup
ON = RS-232 Setup mode (RS-232 mode only), OFF = Normal mode, network active
LOAD DEFAULTS: Toggle the switch 3 times within 5 seconds after powering up.
+ DIP2
Not used
+ DIP3 –Security
ON = Secure mode (HW protection) –no configuration changes possible
OFF = Unsecure mode –configuration not protected by HW
+ DIP4 –RS-485 Echo
ON = RS-485 bus Echo mode –communication forwarded to the RS-232 port

To restore factory default settings: Toggle the DIP switch at least 3 times within 5 seconds
after powering up the device.
DIP3 –HW security protection
When DIP3=ON, the HW-Security protection mode is active. Any configuration changes are
ignored in this mode:
No settings can be changed with UDP Setup (using UDP Config or Herkules utilities)
Flash Setup still opens in the browser but no settings can be changed
TCP Setup (at port 99 by default) is not available
No parameters can be changed over SNMP

Port 3 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 1250 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.
