Page 3: General Features
General Features The new line interface FT634a is completely constructed in SMD-technology. The connections are pin-compatible with the former version, but instead of male connectors there are female connectors. The line interface is used to remotely operate a two-way radio by a 2- or 4-wire connection. It is possible to bridge very long distances depending on the cable attenuation. - Page 4 Channel switching Remote switching of channels is achieved by transmitting certain 5-tone sequences. The interface to the two-way radio device is parallel. The channel switching status output can be "binary", "binary-1", "decimal" and "2xBCD". The channel output can be inverted if necessary. Option line monitoring The operating mode line monitoring can be configured for the FT634aCL.
- Page 5 Examples Depending on the setup of the radio installation different versions of the FT634a can be used. The following questions should be answered when planning: - Interface connection of the FT634a to an operation terminal or a two-way radio set - Remote channel switching necessary - Line monitoring necessary - 2- or 4-wire connection, simplex or duplex...
