6.4.1 Sonar Interface Module (SIM) Block Diagram
6.4.1.1 SIM Power Requirement
The SIM operates within a voltage range of 90 to 260 VAC. The mains voltage is converted in the
various DC voltages required for the operation of the Sonic MBES. Primarily, 48 VDC is sent to the
Receive Module to power the sonar head.
6.4.1.2 SIM Controller
The SIM Controller card primarily does time stamping of sensor data and deals with RS-232 and BNC
data.
6.4.1.3 SIM – Sonic Control 2000 interfacing
Sonic Control 2000 communicates with the SIM over the Gigabit Ethernet DATA RJ-45. Commands,
from Sonic Control 2000 are transmitted to the SIM and then to the Sonic MBES. The Sonic MBES
data passes through SIM to the data collection software.
6.4.1.4 SIM – RS-232 / Ethernet Interfacing
The SIM receives the GPS PPS and time message (NMEA ZDA), the sound velocity from the probe
near the sonar head and the motion sensor data (for roll stabilisation only). These data are routed
through the SIM Controller to the Ethernet switch for transmission to the sonar head.
