[email protected] www.sonardyne.com Datasheet Wideband Mini Transponder (Remote Transducer Version) Description Sonardyne’s existing Wideband SubMini transponder (WSM) is typically interrogated by a responder trigger sent down the ROVs’ umbilical or a narrow band tone signal. In some situations, reverberation or multipath of the tone interrogation can cause interference problems. The WMT is Sonardyne’s first mini-sized transponder. It is slightly larger than the WSM and provides full two-way Wideband interrogation and reply which completely mitigates interference from and to other users. For use on ROVs, the WMT includes responder trigger, an integrated rechargeable Li-ion battery pack that is charged from the ROV’s power supply, and full RS232 communications enabling channel set up, power and gain etc. to be changed from the surface. An On/Off switch helps to ensure the internal battery is not discharged when not in use. When an umbilical trigger is not available, then the full Wideband transponder mode provides excellent USBL performance from a small, lightweight package. Key Features Remote omni or directional transducers are available for both the WMT and existing WSM range. These make installation on an ROV easier as the remote transducer can be installed where there is good lineof-sight and is easily replaced if damaged. • Li-ion rechargeable battery pack The main body of the transponder can then be installed within the ROV frame where it is well protected from damage. • Choice of right-angle or straight connector style • Full two-way Sonardyne Wideband®2 interrogation and reply – mitigates any interference and multi-path issues • Mini size – lightweight and small • Responder mode • Pressure sensor fitted as standard • Full RS232 control from the surface • External On/Off switch • Choice of standard cable lengths: 0.6 m or 3.0 m, custom lengths available on request • Field proven Designed for: Sonardyne Global Headquarters T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E.
