Essential details:RSER200-4 serial line module
The RSER200-4 is a module in the Kongsberg RIO200 modulefamily. These modules provide functions such as I/O interface.network hub/repeater and serial line interface. They have thesame shape and are mechanically mounted on a horizontaldual-rail system.
The RSER200-4 is a four channel, galvanic isolated, serialline, interface module that can be linked to one, two or threecontrollers (RCUs). The four feld channels are individuallyconfigurable as either RS232, RS422, RS485 or NMEA 0183 forconnection to field equipment. There are three Link Channelinterfaces for connection to the controllers.The RSER200-4 is powered by the RBUS connectors.The RSER200-4 contains the following features:Isolated serial line feld channels
Run/error LED on front showing module statusBlinking LEDs on front showing transmit and receive dataactivity for each channel
All internal voltages are monitoredAllow hot module replacement
Compliant to standards IEC 60945 and IACS E10

RSER200-4 serial line module
The RSER200-4 is a serial line module used for connectingserial line equipment to RCU(s) in single or redundant controllersystems.
The module can be connected to up to three controllers (A, B, C)via the three RJ45 connectors (Pl. P2, P3), and up to four feldequipment(1,2,3,4)via the four terminal blocks(Xl.X2.X3X4).
The module contains a USB interface (P4) intended for test andservice purposes. It provides functions to monitor the serial lineactivity and the general status of the module.
The RSER200-4 consists of the main function blocks as shownin the function diagram (see Figure l for block/function diagramof the RSER200-4).
Power supply
Processor and channel logic
Link and feld interfaces
USB interface
LEDs (Status. RX and TX)
The illustration in fgure below shows the switching principlesOfRSER200-4.
One controller (A, B or C) can send serial data via oneRSER200-4 module to four serial line feld channels. This isachieved by de-multiplexing.
Dual or triple redundant controllers can be connected to themodule. The controllers will receive data simultaneously, butonly one is allowed to send. The logic for which controller(A,Bor C)that shall send is determined by the controllers.
