Detailed Information -
SeaCAT/Sealogger RS-232 & Navigation Interface Box, PN 90488 (AC-powered) or PN 90545 (DC-powered) - Manual     See SBE 21 Configuration
SBE 45 Power, Navigation, & Remote Temperature Interface Box, PN 90402 - Manual     See SBE 45 Configuration

Sea-Bird manufactures several types of Interface Box, designed for use with specific products and for specific applications. Depending on application, an Interface Box includes a combination of the following functions: RS-232 to RS-232 junction box, optical-isolation, power, NMEA interface, and/or remote temperature interface.

Brochure/specifications - html or pdf     Application Note 17: Instructions for Use of SBE 14     Configuration options & accessories

The SBE 14 provides a visual display of CTD depth, pressure, or altitude, as well as a pressure / altimeter / bottom contact alarm. The SBE 14 is housed in a rugged, spray-proof package suitable for mounting at the winch operator's position, and provides an easy-to-read display. It is compatible with a number of Sea-Bird profiling CTDs.

Sea-Bird's inductive modem uses a mooring cable as the communication link, permitting the underwater instrument(s) to be easily positioned at any depth without the use of cable connectors. See the following for technical details and a schematic of an inductive modem system:

• Real-Time Oceanography with Inductive Moorings and the Inductive Modem Module (Application Note 92) -- Technical paper provides background information on inductive modems, principles of inductive coupling, mooring configurations, use in fresh water, system components, mooring cable and cable fitting resources, and a summary of OEM components available from Sea-Bird.
• Typical Inductive Modem Mooring Components -- Schematic provides a pictorial overview of an inductive modem system.

The system is run by an Inductive Modem Module (IMM) or Surface Inductive Modem (SIM). Sea-Bird instruments that are compatible with this system include: SBE 16plus-IM V2 SeaCAT C-T (P optional) Recorder, 37-IM and 37-IMP MicroCAT C-T (optional P) Recorders, 37-IMP-IDO MicroCAT C-T-DO (optional P Recorder), 37-IMP-ODO MicroCAT C-T-DO (optional P Recorder), 39-IM Temperature Recorder, 44 Underwater Inductive Modem, and Underwater Inductive Modem Module (UIMM).

Specifications are subject to change without notice.
