    1. About the RDi 20...
  • Page 7 The RDi 20 Radio Data System (RDS) Generator adds text to FM programming in the form of station branding, Program Associated Data (PAD) and other information. Listeners want to know “what’s happening now”. To improve the immediacy of PAD, the RDi 20 RDS generator increases the rate at which receiver RadioText is refreshed. RadioText is the 64-character message display available on more sophisticated receivers.

  • Page 51 New firmware is frequently released for the RDi 20 to add new features and functionality. To upgrade the RDi 20 firmware with the newer release, the upgrade is transferred from a PC to the RDi 20 using a Telnet session. HyperTerminal, an application released with the Windows operating system, is most commonly used.
  • Page 52 Select the appropriate connection port from the Connect Using drop-down box. If using TCP/IP (Winsock) enter the RDi 20 IP address in the Host Address field and click to initiate the session. If using a COM port, configure the port setting as shown, click Apply, then click to initiate the session.
