Surface Inductive Modem (SIM)     Brochure/specifications

Part # Description Notes
SIM-COUPLED Surface Inductive Modem PC board (PN 40928) with RS-232/485 interface for use with Sea-Bird Inductive Cable Coupler (formerly SMODEM-1). Includes 3 m serial cable, PN 171887.
Communicating with 1 or more IM instruments (SBE 16plus-IM, 16plus-IM V2, 37-IM, 37-IMP, 37-IMP-IDO, 39-IM, 44, or UIMM) requires use of Surface Inductive Modem (SIM), which provides standard serial interface (RS-232 or RS-485) between user's computer & up to 100 IM-compatible instruments coupled to single cable. SIM is housed in buoy or on land.
Note: IMM can be used in place of SIM; see below.

 		 For typical cable-to-buoy applications, it is often preferable to connect jacketed mooring wire to buoy with length of chain, grounding jacketed wire to seawater at each end. Inductive Cable Coupler (ICC) connects SIM to jacketed wire above uppermost underwater inductive instrument & below point where wire is grounded. Order SIM-COUPLED & Inductive Cable Coupler (ICC); see ICC listing below.
For typical cable-to-shore applications, bottom end of wire is grounded to seawater, & top end remains insulated all way to connection to SIM. Second wire from SIM connects to seawater ground, completing circuit. Order SIM-DIRECT.
SIM-DIRECT Surface Inductive Modem PC board (PN 40870) with RS-232/485 interface for use with direct mooring wire termination to Surface Inductive Modem board (formerly SMODEM-2). Includes 3 m serial cable, PN 171887.

Second wire from IMM connects to seawater ground, completing circuit (see drawing above).

 

 

Inductive Cable Coupler (ICC)     Brochure/Specifications

Part # Description Notes
ICC Inductive Cable Coupler Communicating with 1 or more IM instruments requires use of Surface Inductive Modem (SIM) or Inductive Modem Module (IMM), which provides standard serial interface (RS-232 or RS-485) between user's computer & up to 100 IM-compatible sensors coupled to single cable. An Inductive Cable Coupler (ICC) is always required if specifying SIM-COUPLED, & is often required if specifying an IMM.

Version 4a ICC is a 20-turn coupler, while Version 4b is a 100-turn coupler. Other couplers are available for OEM applications (contact Sea-Bird for ordering information). Table below summarizes power requirements for each:

  20-turn ICC
(Version 4a)		 100-turn ICC
(Version 4b)		 8-turn ICC
(OEM Version)
SIM 35 mA 20 mA Not allowed
IMM --
Low power transmit setting (1)		 Not allowed 1.2 mA Not allowed
IMM --
Full power transmit setting (1)		 12 mA 4 mA Not allowed
Underwater Inductive Modem
(UIM) (2)		 Not allowed Not allowed 15 mA

Notes:
(1) IMM power setting is set with SetEnableFullPwrTx= command.
(2) Underwater Inductive Modem is a component used by OEMs to integrate Sea-Bird's inductive modem technology with a third-party sensor.
