he TC2100 Multi-Drop Fiber Optic Modem provides maximumreliability for linking monitoring devices (typically RTUs or PLCs)
to a Host Controller or CPU. It is completely transparent to data orcommunicationsprotocols.
TheTC2100canbeconfiguredinRingorSelf-HealingRingtopologies.TheSelf-HealingRingschemeissophisticated, i.e. itdetectsupstreamanddownstreamfailuresonbothTxandRx,andautomaticallyre-routesanycableorequipmentfailure.TC2100masterandTC2101slaveunitsareinterchangeablebysettingadipswitch.“Multiplemaster”unitsareoptional.
It supports asynchronous data rates up to 38.4 Kbps. ElectricalinterfacesareRS-232,RS-422orRS-485.TheRS-485electricalportcanbemulti-dropped.Therearetwooptionalversions(ModelTC2100T)forextremetemperatureapplications(-20°Cto70°C&-40°Cto80°C).
Each unit comes standard with two pairs of fiber interfaces andeither 2-Channel RS-232 or 1-Channel RS-422/RS-485 interfaces. ThesecondchannelontheRS-232interfacecanbeusedfordata,RTS/CTShandshakingsignalsorasatelephoneextensionwiththeModelTC1900“Quick-Talk”phoneadapter.
