RCOM 4987, 4988, 4989 are designed for communication with AADI real-time monitoring systems. Measured data are received, stored and forwarded into new or existing network. The units are developed for AADI by Develogic GmbH. Communication Unit 4987 is designed for use in fixed installations. Communication Unit 4988 is designed for AADI Data Buoy. Communication Unit 4989 is designed for receiving stations. • Establish a two-way radio link between the measuring and the receiving station • Multipoint to point connection for communication between several measuring and one receiver station • Reliable communication due to data validation and retransmission. • Data filtering and compression -only relevant data are transmitted • RF modem, GPRS and satellite transponders available • Status messages like e.g. GPS position, radio link quality and supply voltage • Two way direct link between the TCM and SEAGUARD® for instrument configuration • Data are converted into a format described by the customer • Data from connected instruments are stored on an SD card.3 Measurement ranges: 0 - 300m, 0 - 2000m, 0 - 6000m RCOM units 4987, 4988 and 4989 are designed for transfer of data between AADI real-time monitoring systems. still not error-free, an error message are saved in a separate log file. Unit 4987 and 4988 are equipment for the transceiver module, while unit 4989 is for the receiver module. The units are equipped with a TCM for e.g. data quality control and instrument configuration. Data are transmitted on regular intervals and can be set to other interval than the instruments’ logging interval. The communication units will establish a two-way radio link between measuring stations and the receiving station. Measured data are received, stored and forwarded into new or existing network by converting incoming data to format described by the customer. Data from connected instruments are received on separate com ports. After checking for errors in the transmission from the instruments, data are stored in individual files on SD card. Data with errors will be re-transmitted from the instruments; if a message is Data are packetized and checksum is added for data quality control on the receiving end. The TCM are able to synchronize the instruments’ internal clock with the GPS time on regular intervals. Default synchronization interval is once per day. The radio modem are powered from the TCM. The RCOM units will interface AADI instruments and sensors to radio modems. On-board GPS receiver enables position reporting and time synchronizing for the instruments.
