CSA 300 Class A Transponder

Product Specification
The CSA 300 is a very compact Class A Transponder suitable for all vessels from large commercial ships, super yachts, fishing vessels, pilot boats, through to leisure boats. The transceiver and the high contrast monochrome display are both contained in a single robust enclosure. Connected to an external VHF antenna and its GPS antenna the CSA-300 transmits its own position and vessel data, as well as receiving information from other AIS transponders. Designed and IMO approved to meet the requirements of large commercial vessels it is equally suitable for smaller commercial, fishing and leisure craft.

Features include:

  • Very compact design and simple installation.
  • Automatic transmission of vessels own position, speed and heading to other vessels within VHF range.
  • The ability to plot the progress, changes in heading and speed of other AIS vessels, AIS navigation marks, AIS SARTs  on a Chart Plotter , Radar or PC program. With reception from both Class A and Class B vessels, AIS Aids to Navigation, AIS Base Stations and AIS SARTs.
  • Receive and Transmit Text, Binary and Safety Messages.
  • Automatic transmission, dependent on speed and rate of turn.
  • A method of monitoring the position, speed and heading of other AIS vessels within VHF range.
  • Text and (simple) graphics display of vessel details received.
  • Simple access to data and menus with the rotary control
  • Inbuilt AIS Pilot Plug and RS232 (PC) interfaces plus compact external junction box.
  • Internal 16 channel GPS receiver and three VHF radio receivers.

Both AIS Pilot plug and RS232 ( PC) interfaces are built into the unit. Where needed the included external remote junction box gives connections for output to electronic chart displays, Radar and other AIS displays. The junction box also provides connections for external inputs (Heading, second external GPS etc) where these are required.

Included in the box with the CSA 300 unit are: Data cable, Junction box, Power cable, Trunnion bracket, Panel mount brackets, Fixing screws, User and installation manuals, Quick start guide, Support tools CD, Mounting template.
