Poseidon 1250 - technical specification

Czech version

English version

• Ethernet: RJ 45 - 10BASE-T / 10 Mbit/s
• Port 1: RS-485 (connector RJ45)
• Port 2: 1-Wire (connector RJ12)
• Port 3: RS-232 (connector Cannon 9 Male)
• 3x Binary input: terminal board for 3x contact (0 to 500W)  
• Device setting:
  • locally - RS-232 Setup - sensor initialization and configuration, IP address configuration etc.
  • UDP Config - IP address configuration etc.- does not work remotely, but only on a local network segment
  • Over HTTP - Flash graphical interface- password and IP address range protection
  • Over SNMP - only some parameters
     
• Ethernet communication interface:
  HTTP - WWW page - (see Online demo), XML, Modbus over TCP, SNMP, SNMP traps

Binary inputs for direct connecting of three contacts (digital inputs, or dry contacts). Each input has independent Alarm status for Disconnected or Closed The inputs use the same (Common) input but all 3 are separated from power supply segment of the Poseidon. Designed for connecting door, angle, flooding, air-flow and power supply failure sensors.

 FAQ & Support

Q: Enables Poseidon 1250 model to log values retroactively?
A: No, the Poseidon 1250 model accesses measured data for the Ethernet. Poseidon model 2251 can log measured values, it logs to round buffer circa 40 000 values in Flash memory and synchronizes real time over the network via NTP.

Q: What SW do you recommend?
A:  Poseidon uses common protocols, so you can use any SW that works with XML, or SNMP. To lower your efforts we prepared description how to start working with the Poseidon and some SW. You can find details in manual or on specialized page about SW and interfaces: Poseidon – communication interface.

Q: Are or will be available any other sensors?
A: Yes, we work on new sensors, already now a converter for connecting current loop (0 to 20 mA, 0 to 10V) is available, etc.

Q: Is available any free SW which can read data from the Poseidon and draw graphs?
A:  We work on implementation of Poseidon support to some SW, specialized for example in food industry. Contact us for further information.

Q: You present the option to connect up to 40 sensors to the Poseidon. Is it possible to detect which sensor is which via SNMP?
A:  Yes, every sensor has its unique number. It is 2 bytes section from serial number of 1-Wire sensors and the address on the bus of RS-485 sensors. This value (Sensor ID) is available over WWW, XML, ModBus/TCP and over SNMP. If you replace for example 1-Wire sensor with another, it is necessary to run sensor autodetection again, otherwise it is not possible to see the new sensor in list of connected sensors.

Q: First you present possibility to connect up to 42 sensors to the Poseidon unit and then the number varies. How is it?
A: The number of sensors is limited by model and bus that are sensors connected to. Generally following three restrictions apply::
    - 10x 1-Wire thermometer
    - 25x HTemp-485 temperature + humidity
    - 31x Temp-485 thermometer
    - 3x Dry Contact input
All together up to 42 sensors which can work at a time

Q: How is the security of remote device solved?
A: It is possible to configure range of IP addresses, that the device communicate with. SNMP and HTTP can be password protected.
For online presentation purposes it is possible to switch to a mode using DIP3, where the user operates the device but remote change of configuration is blocked.

Q:  You mention that the RS-485 bus with sensors must be terminated. Do you mean that I have to terminate every single sensor?
A: NO, you can find detailed instruction in every RS-485 bus description. You simply apply the terminator always and only on the last sensor on the line.

Q: Is it possible to switch on / off PC via Poseidon?
A: Yes, the 1250 model enables you to operate 2 output pins on Port 3 (RS-232). You can connect them to a relay and to PC reset button.
