SPA-ZC400MMP and SPA-ZC400MMGThe optional interface provides a connection between the REF 541/3/5,REM 543/5 or RET 541/3/5 device and the fibre-optic SPA and LON. Thebus connection module converts incoming optical signals from the SPA andLON bus to electrical RS-485 signals for the REF 541/3/5, REM 543/5 andRET 541/3/5 devices and vice versa. It contains a service pin for LON nodes.The optional interface can be used in loop- and star-type bus topologies. It ispossible to select the idle state of module line. The light can be turn on or off.The jumpers select the bus topology (loop or star) depending on whether thelight is turned on or off.In the loop topology, the interface receives the message from the fibre-opticinterface and passes it both to the fibre-optic transmitter and to the RS-485interface. In the star topology, the interface receives the message from thefibre-optic receiver and passes it only to the RS-485 interface. If the messageis received from the RS-485 interface, it is passed to the fibre-optictransmitter in both bus topologies.The SPA bus communication uses loop and light off modes, when the modulejumpers are in loop- and light off- positions. The LON bus communicationuses star and light off modes, when the module jumpers are in star- and lightoff-positions.In the LON bus communication the optional interface supports collisiondetection. The service pin is connected via the RS-485 interface to thedevice's Neuron chip, which is connected to the interface.Table 3.1.-1 Settings of the jumperTopology Light on/off ProtocolStar Light off LON/SPAStar Light on Not supportedLoop Light off LON/SPALoop Light on Not supported14SPA-ZC 400 Ethernet AdapterModbus/TCP BrigdeInstallation and Commissioning Manual1MRS756014
