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. The FT634a is the simplest and most reasonable version. There are 6 different versions of the line interface FT634a. All versions offer the following features:

All versions of the FT634a 
  • - 2 or 4 wire connection (selectable by jumper) 
  • - Impedance 600 Ohm or Zr (selectabel by jumper) (Zr only for 2-wire) 
  • - Connector radio device --> AF-in/output and PTT-out 
  • - Pilot tone decoder 3300 Hz or DC-decoder - Serial interface RS232 to adjust and program 
  • - All levels adjustable with RS232 - All AF-in/outputs galvanically separated (transformer)
