Communication Controller E924
We regret to inform you that this product is DISCONTINUED; please find our current products here
Designed to provide a highly reliable outstation subsystem, the unit has been engineered using the latest surface mount and microcontroller technologies to provide a compact,
programmable device incorporating several new features. The E924 performs necessary GSM communication between an outstation (a lighthouse, or a buoy system) and the monitoring and control centre to report pre-programmed events, measurement values, warnings, error conditions, etc. It is capable of communicating with the equipment within outstation local area network (LAN) to obtain the above values, and to perform timing control as necessary.
Features
- Communication with the computer of the control centre via GSM-900 mobile telephone network
- Communication with up to 23 nodes connected to the LAN
- Regular polling of LAN nodes (other units of lighthouse or buoy equipment) in every 15 minutes
- Regular communication sessions in accordance with the pre-programmed time schedule
- Immediate transfer of emergency messages to the control centre
- Responding to remote commands and inquiries of the regional control centre
|
|
- Adjusting of the built-in clock/calendar and the clocks of other nodes based on the signals received from the control centre
- Periodical measurement and recording of 5 analogue input signals in every 15 minutes.The results of last 256 measurements are always available
- Continuous checking of contact sensors (tampering, fire, etc.) and sending of the emergency messages to the control centre when necessary
- Logging of the statistical data about the quality of the communication sessions, and the times of the last 32 communication sessions
- Low-power standby mode of mobile phone between the communication sessions in order to spare energy
- Rugged nitrogen-filled aluminium enclosure
