This module is a mezzanine module, and can be placedon the Analog/Digital conversion module (ADM). The serial communicationmodule can have connectors for two plastic fibre cables (snap-in) or two glass fibrecables (ST, bayonet) or a combination of plastic and glass fibre. Three differenttypes are available depending on type of fibre.The incoming optical fibre is connected to the RX receiver input, and the outgoingoptical fibre to the TX transmitter output. When the fibre optic cables are laid out,pay special attention to the instructions concerning the handling and connection ofthe optical fibres. The module is identified with a number on the label on the module.The procedure to set the transfer rate and slave number can be found in theInstallation and commissioning manual for respective IEDs.15.4.3 DesignWhen communicating locally with a computer (PC) in the station, using the rearSPA port, the only hardware needed for a station monitoring system is:• Optical fibres• Opto/electrical converter for the PC• PCWhen communicating remotely with a PC using the rear SPA port, the samehardware and telephone modems are needed.The software needed in the PC, either local or remote, is PCM600.When communicating between the local HMI and a PC, the only hardware requiredis a front-connection cable.Section 15 1MRK 505 208-UEN BStation communication578Technical reference manual
