Kongsberg RSER200-4 603444 input module Marine systems

KONGSBERG RSER200-4 (Item Number 603444) Four-Channel Serial Communication Input Conversion Module
I. Basic Identification Information
Full Model: RSER200-4 Remote Serial Communication Module
Original Part Number: 603444, belongs to the RMP200 series distributed IO hardware platform
Compatible Systems: K-Chief 600 engine room monitoring, K-Pos DP power positioning, AutoChief remote control system for the entire Constructions & Maritime automation system
Core Function: 4 independent isolated RS485 serial gateways, connect third-party serial port instruments and sensors to the RBUS system bus, act as the remote serial acquisition station for the RCU501/RAIT400 main controller, not an ordinary digital input DI board card

4-Channel Serial Channel Hardware Specifications
Channel Architecture
Four fully isolated RS485 field serial ports, each with independent photoelectric isolation (with an isolation voltage of 500V), eliminating interference from ground loop potential differences on the ship
Standard electrical levels: RS485 differential signal, supports 2-wire half-duplex
Baud rate software adjustable: 300 – 115200 bps, compatible with most marine instruments
Frame format: Configurable 8N1/8E1/8O1 standard serial port protocol
Protocol Compatibility
Native support: Modbus RTU, NMEA0183, various manufacturer’s proprietary instrument protocols (temperature transmitters, level radars, speedometers, flow meters, pressure recorders)
Hardware Buffering
Each channel has independent hardware FIFO cache to prevent data packet loss at high speeds; supports software switching between master and slave modes, can act as a bus master polling instruments, or act as a slave to receive upper-level instructions
