For Point-to-Point Medium Speed Data Applications  

 TTL/RS-422 Application   

The Luxlink system consists of two DX-7201 transceivers or the DT-7201 transmitter and DR-7201 receiver. All units utilize pure digital on-off modulation to transmit high-speed data signals in accordance with standard RS-422 or TTL specifications. No conversion, sampling or other data manipulation is employed.

The DX/DT/DR-7201 is easily user-configured for either of the above protocols by setting an internal DIP switch. Operation otherwise is totally adjustment free. The system may also be used for protocol conversion if desired. Integral indicators are provided on both units to continuous indicate the presence of data signals as well as operating power thereby making system troubleshooting simple.
