Description
Kongsberg Simrad 382-219490 TX(MF) Transmitter Board
Product Introduction
The Kongsberg Simrad 382-219490 is a dedicated TX(MF) transmitter board used in Kongsberg Maritime acoustic equipment. Kongsberg’s official TTC 400 instruction manual lists part number 382-219490 as the TX(MF) transmitter board, alongside the 382-083602 RX receiver board, 382-219335 16 MHz microcontroller board, power supply, battery charger, and motherboard.
The Kongsberg Simrad 382-219490 is also documented in the ACC 401 system. Kongsberg identifies it specifically as the MF30 kHz transmitter board, with one transmitter board installed in the ACC 401 MF unit. The associated system includes the 382-083602 receiver board, 382-219335 microcontroller board, 382-219052 battery charger board, and 382-098602 48 VDC/1 A power supply.
From a maintenance perspective, Kongsberg Simrad 382-219490 should therefore be treated as an acoustic transmitter PCB rather than a generic control or PLC board. Its function depends on the host TTC/ACC architecture, acoustic transducer, receiver board, controller, and power circuitry. Current physical listings identify the board as 382-219490 Rev. B / 381-083606, and describe it as a TX(MF) transmitter card for ACC 401 / TTC 400. That revision and secondary board marking should be checked against the installed unit before procurement.

The 30 kHz MF designation is directly supported by Kongsberg’s ACC 401 manual. The 48 VDC/1 A power-supply figure belongs to the associated 382-098602 power supply, not to the transmitter board itself and should not be interpreted as the standalone supply specification of 382-219490.

382-219490
Main Features and Engineering Considerations
Medium-Frequency Acoustic Transmission
The primary function of 382-219490 is acoustic transmission. In the ACC 401 documentation, Kongsberg identifies it as the MF30 kHz transmitter board. This places the board in the acoustic signal chain rather than the vessel’s conventional automation I/O layer.
TTC 400 Integration
The TTC 400 spare-parts table lists 382-219490 as the TX(MF) Transmitter board. It is one of the unit’s main line-replaceable modules and operates alongside the 382-083602 receiver board and 382-219335 microcontroller board.
ACC 401 System Integration
The ACC 401 parts list provides a useful system-level view. It identifies one 382-219490 transmitter board, one 382-083602 receiver board, one 382-219335 CPU/microcontroller board, one battery charger board, and the associated 48 VDC power supply.
Related Number 381-083606
Current physical listings associate 382-219490 Rev. B with 381-083606 and describe the assembly as a TX(MF) transmitter card. This is useful when inspecting an existing PCB, but the two numbers should not automatically be assumed to represent separate interchangeable orderable items.
Revision Control
A current physical listing identifies Rev. B. For legacy acoustic electronics, revision matching is important because component substitutions, calibration, output-stage changes, or interface modifications may exist between revisions.
Application Scenarios
- Kongsberg TTC 400 acoustic transponders
- Kongsberg ACC 401 acoustic control units
- ACC 401 MF30 kHz systems
- Marine acoustic positioning equipment
- Underwater acoustic transponder systems
- Shipboard acoustic control equipment
- Maintenance of legacy Kongsberg/Simrad acoustic electronics
- Replacement of failed MF transmitter boards
Engineer’s Guide: Field Pitfalls
1. Do not classify 382-219490 as a PLC output card.
Kongsberg identifies it specifically as an acoustic TX(MF) transmitter board.
2. Verify the host equipment.
The board is documented in both TTC 400 and ACC 401 systems, but the complete system architecture still needs to match.
3. Check the receiver board.
The associated 382-083602 is the RX receiver board. It should not be confused with the transmitter board during maintenance.
4. Check the microcontroller board.
The ACC 401/TTC 400 architecture also uses 382-219335 as the microcontroller board. A transmitter-board fault should therefore be diagnosed within the complete control chain rather than by board substitution alone.
5. Verify the acoustic transducer and cabling.
A transmitter-board replacement cannot correct an open, degraded, or incorrectly terminated acoustic transducer circuit. Inspect the associated cabling and connectors before condemning the PCB.
6. Match the PCB revision.
Rev. B is documented on available physical units. Record the revision printed on the original board before ordering a spare.
7. Perform functional acoustic testing.
A successful power-up does not prove that the transmitter output stage is functioning correctly. The replacement should be checked using the applicable Kongsberg test and configuration procedure.
Frequently Asked Questions
What is Kongsberg Simrad 382-219490?
It is a TX(MF) transmitter board used in Kongsberg acoustic equipment, including the TTC 400.
What frequency does the ACC 401 version transmit?
Kongsberg’s ACC 401 documentation identifies 382-219490 as the MF30 kHz transmitter board.
Is 382-219490 the receiver board?
No. 382-083602 is the receiver board. 382-219490 is the transmitter board.
What is 381-083606?
Available physical-board records associate 381-083606 with the 382-219490 transmitter-board assembly. A current listing identifies the combination as 382-219490 Rev.B / 381-083606.
Is 382-219490 used in TTC 400?
Yes. Kongsberg’s official TTC 400 manual lists 382-219490 — TX(MF) Transmitter board as one of the main TTC 400 modules.
Is 382-219490 a complete transmitter?
No. It is a PCB/module within the acoustic system. The complete equipment also includes the controller, receiver, power supply, battery system, motherboard, cabling, and acoustic transducer.
Procurement Note
For Kongsberg Simrad 382-219490, the identification is well supported by Kongsberg documentation: TX(MF) Transmitter Board. The ACC 401 documentation further specifies its MF30 kHz application.
When sourcing a replacement, retain the full 382-219490 number and check for the associated 381-083606 marking and board revision. If the application is TTC 400 or ACC 401, identify the complete host-unit model as part of the purchasing record.
Do not copy the 48 VDC / 1 A figure from the ACC 401 documentation into the transmitter-board specification. That rating belongs to the separate 382-098602 power supply. The transmitter’s own electrical requirements and output-stage characteristics should be confirmed from the applicable Kongsberg service documentation before bench testing or installation.
