Product Overview
The KONGSBERG RSER200-4 is a four-channel serial line interface module belonging to the Kongsberg RIO200 remote I/O family. Kongsberg documentation identifies it as Part No. 603444. The module provides galvanically isolated serial communication between field equipment and one, two, or three RCU controllers, making it suitable for marine automation, vessel control, navigation, and remote I/O applications. Each of its four field channels can be configured for RS232, RS422, RS485, or NMEA 0183 communication. Three RJ45 link channels connect the module to the controller network, while the RBUS provides power and system communication.

Installation and Maintenance — RSER200-4
Before replacement, record the existing module part number, revision, serial number, terminal wiring, channel configuration, and connected controller arrangement. Each field channel may use a different serial standard, so the wiring should be verified against the approved system documentation rather than assumed from the connector position.
The module mounts on a horizontal dual-rail system and connects through RBUS A/B interfaces. During replacement, ESD precautions should be observed when handling field wiring and electronic circuitry. After installation, confirm the module status LED, controller communication, transmit/receive activity, and each connected serial device.
Product Warranty — RSER200-4
Warranty coverage depends on the supplier, product condition, and purchase agreement. For marine automation spares, it is advisable to confirm the exact Kongsberg part number 603444, hardware revision, serial-number traceability, test status, and warranty terms before procurement.
The KONGSBERG RSER200-4 is a specialized serial communication module rather than a conventional digital I/O card. Personally, I would verify the field-channel protocol and RIO200 architecture first; that check prevents most compatibility problems when replacing this type of marine automation hardware.
