6. ity Connections Several recorders with internal or external sensors are placed on site and are interconnected with one cable while galvanically isolated from each other Common Timing One of the interconnected recorders commonly referred to as the Software Master is enabled to synchronise and update the internal clock of each of the other recorders commonly referred to as Software Slaves via the network to achieve Common Timing All stations within the network use this common time information to synchronise their internal time The time synchronisation is a permanent task for the Software Master The stations within the network permanently check their synchronisation status In case of not having the network time information available the Slave stations base on their internal real time clock The time of the last successful synchronisation is available in the status information of a Slave station and is written into every event header A GPS time source can be connected to the Software Master to achieve the time synchronisation of the whole array to the absolute time which allows easier correlation with recordings made by other arrays or recorders Common Trigger Triggering functionality of each recorder can be controlled using three flags Internal Trigger Network Trigger Output and Network Trigger Input By enabling or disabling these flags the behaviour of each station can be defined precisely as needed in the particular applica
7. s The update of the date and time of the slave stations can take several minutes A simple way to check the wiring during the installation is to verify the arrival of the network signals to an instrument For this test the recorders need to be configured correctly The following LED s can be found on the interconnection cards GS ICC V5 inside the recorder by removing the black plastic cover i Caution High Voltage If you remove the black plastic covering the base part of the recorder housing do not touch any electronics inside e LED90 yellow Blinks in all recorders e LED91 red Blinks in the recorders configured as Network e LED92 green Blinks in the recorder configured as Software Master and during a trigger also in the corresponding Software Slave The communication option can be tested by simply trying to establish a connection to the instruments from a Computer running GeoDAS The standard communication speed for Interconnection Networks is 38 400 Baud

9. tion This functionality can be summarised as follows e Enable disable self trigger The station triggers if an internal trigger condition is fulfilled and the Internal Trigger flag is enabled e Enable disable sending trigger to network The station transmits an active trigger message to the network if an internal trigger condition is fulfilled and the Network Trigger Output flag is enabled e Enable disable accepting trigger from network The station triggers if an active trigger message arrives from the network and the Network Trigger Input flag is enabled If a station is not synchronised to the network it records based on the specified internal trigger condition An output for Local Communication is available at each recorder for local data retrieval and setting of parameters The reliability of the monitoring network is high because a malfunction of a recorder would affect only the location of malfunction in the array If the network is interrupted each of the recorders will perform as a stand alone recorder by recording whenever the instruments event recording trigger level is reached 2 1 1 Type CCL Common Time Common Trigger Local Communication This type of array enables common triggering and common time in the simplest form The data are stored locally in every recorder and have to be retrieved locally from each recorder separately due to the GS _ GSR GCR _UserManual App K Interconnection ILFDC VO2 doc
