1. About the RDi 20

1-1
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. When an event occurs, such as a new song
starting, the RDi will decrease the time necessary for new information to be displayed.

1.1 A Note on System Settings
All system parameters are stored in a battery backed NVRAM. The Lithium battery that holds these
parameters has a life of about 10 years. The battery is replaceable and the RDi 20 will enter a warning/
fault state at power up if the backup battery needs replacement. In this state, the system parameters
are considered unreadable and the unit must “fail safe”. The default configuration is therefore to
bypass (disable) the RDS output.
In addition to the low battery signal, a CRC is also used to verify the NVRAM contents and thereby
prevent the RDi 20 from reading potentially corrupt system parameters.

1 MPX In Serial data input from BE’s TRE or similar product. This is a D9F
connector with DCE pin-out (see Figures 4 and 4A). Both the MPX
In and MPX Thru connectors have a passive bypass relay such that
multiplex data will pass thru to the next device in the chain even if the
RDi 20 is powered off. This input data may be multiplexed for feeding
additional RDi’s in the future.
2 MPX Thru Used for connecting multiple RDi’s together (cable connectors
supplied). The MPX Thru is a D9M with DTE pin-out (see Figures 4 and
4A). Both the MPX In and MPX Thru connectors have a passive bypass
relay such that multiplex data will pass thru to the next device in the
chain even if the RDi 20 is powered off.
3 MPX Activity LED The MPX Activity LED is lit green when the MPX input is active. The
activity LED will blink momentarily (green-off-green) to indicate an
incoming data packet or switch momentarily red to indicate an error
in the incoming data.
4 Aux 1 The Aux 1 port has the same DTE pin-out as the MPX Thru (see
Figures 4 and 4A). This connection is reserved for future use
5 Aux 2 The Aux 2 port has the same DTE pin-out as the MPX Thru (see
Figures 4 and 4A). This connection is reserved for future use
6 Application Card Reserved for future use.
7 TCP/IP Connection RJ45 Ethernet data input connection from BE’s TRE, Now Playing, or
similar product via a Studio to Transmitter Link (STL).

12 Side Chain/Loop Thru Switch Selects the mode of operation for the Composite IO section.
In Side Chain operation the 19kHz pilot is applied to a sync input
and only the RDS waveform appears at the RDS output. (The RDS
waveform is locked in phase to the applied pilot reference.)
In Loop Thru operation the complete composite signal (including
audio and the 19kHz pilot) is applied to a sync input and a precision
summing amplifier (internal to the RDi 20) adds the incoming
composite signal to the internally generated RDS waveform and the
sum of these signals is presented at the RDS output. Note that in
“loop thru” operation a passive bypass relay is present to pass the
composite signal if the RDi 20 is powered off.

1 Text Display In normal operation the date and time (UTC) is displayed along with
the selected sync input (upper right), the 8 character PS code (lower
left) and current radio text (scrolling area, lower right).
With release of the firmware v0.152 it is now possible to configure
common features of the RDi 20 from the front panel using a
combination of menus on the text display and the encoder (item 9).
2 RDS Logo This is simply the RDS logo, not a status indicator.
3 57 kHz (Subcarrier) Status Lit blue for normal operation, lit red if the unit is in the bypass state
(XEBP=Enabled).
4 19 kHz (Stereo Pilot) Status Lit blue when a 19 kHz reference (stereo pilot) is present at a sync
input and the corresponding sync input is selected (XESS=Input 1 or
XESS=Input 2). This is the normal state for a stereo broadcast with the
RDS subcarrier phase locked to the stereo pilot.
Lit red if a reference is not detected or if the unit is in the bypass
state. Indicator is dark for monophonic broadcast with a “free
running” subcarrier (XESS=Disabled).
5 MPX Activitiy Indicator Lit blue for normal operation. Blinks momentarily (blue-off-blue) on
reception and successful processing of new data on the MPX port.
Blinks red momentarily to indicate reception of corrupt data on the
MPX port.
6 Ethernet Activity Indicator Lit blue for normal operation. Blinks momentarily (blue-off-blue) on
reception and successful processing of new data on the Ethernet port.
Indicator is dark if no link detected (no Ethernet cable attached or
other connectivity issue).
7 Fault Indicator Lit red for hardware fault. (Note that it is normal for this indicator
to light red for several seconds on power up or CPU reset.) Future
versions of the firmware may define additional states for this indicator.

8 Numeric Display The numeric display cycles through a set of three device ID codes.
This includes the PI code in hexadecimal and ASCII form as well as the
station broadcast frequency.
9 Encoder With release of the firmware v0.152 it is now possible to configure
common features of the RDi 20 from the front panel using menus (on
the text display, item 1) and this control. The encoder is rotated left
or right to scroll through menu items and pressed in (clicked) to make
selections.
10 Hardware Reset Button This pushbutton triggers a hardware reset. (Note that the button is
recessed into the panel and a small flat screwdriver or similar tool is
required to actuate it.) This control is normally not used. It is part of a
hardware interlock to force access to the CPU ROM monitor (press and
hold encoder in while momentarily pressing the reset button).
11 Console Port A serial communications port used for initial device configuration
using a terminal emulator as well as installation “uploading” of new
firmware. This port is “DCE” wired and is always configured for
115200 baud, no parity, 8 bits, 1 stop bit.

The RDi 20 can be quickly configured for either 115V (factory default) or 230V operation. On the
rear of the RDi unit there is a fuse block the can be removed, rotated 180˚, and reinstalled to quickly
change from 115V to 230V.

Using a small flat blade screwdriver, gently pry the fuse
block door open.
Gently pry out the fuse block.
Rotate the fuse block 180˚ (so that 230V is on the right
side) and re-install.
Close the fuse block door until it snaps shut.
Install the RDi 20 into a standard 19” E.I.A. equipment rack at the transmitter site.
Connect the AC Power Cord (supplied in kit) to the RDi 20.

The RDi 20 will accept either serial data to the MPX IN port, or ethernet data via the TCP/IP network
port. Most installations will connect a standard ethernet cable (not supplied) from the RDi 20 to the
STL at the transmitter site.
Ethernet communication across the STL may be either UDP or TCP/IP protocol.
If the serial data MPX IN port is going to be used, terminate the serial input cable with the appropriate
connector from the kit. See the following section for pinout.
The MPX and AUX data ports are capable of operating with RS232 or RS422 signaling. (The signal
names change depending on the type of electrical signaling selected for the port.)
The MPX In is the serial data input port and is a DB9F connector with DCE pin-out.
The MPX Thru is a DB9M with DTE pin-out and is used if connecting to another RDi 20.
The AUX 1 and AUX 2 ports are also DB9Ms and have the same DTE pin-out as the MPX Thru.

The RDi 20 subcarrier generator offers two methods for connection into the FM composite chain
known as Side Chain and Loop Thru.
Side Chain is normally the preferred method of connection. The mode switch must be set to the Side
position for this connection method. The 19kHz pilot reference from the stereo generator is connected
(via BNC Cable 947-0020 supplied in kit) to one of the sync inputs on the RDi 20. This allows the RDi
20 to phase lock the 57kHz RDS subcarrier to the 19kHz stereo pilot. The RDS output of the RDi 20 is
then connected (via BNC Cable 947-0020 supplied in kit) to a Subcarrier (SCA) or Aux Input on the FM
Exciter. In this mode of operation, only the RDS waveform is present at the RDi 20 RDS Output and
this signal is mixed into the final composite by a summing amplifier within the Exciter.
Loop Thru is an alternate method of connection that is required in some composite chains. The mode
switch must be set to the Loop position for this connection method. In Loop Thru operation the
composite signal from the stereo generator (containing audio and the 19kHz pilot) is connected (via
BNC Cable 947-0020 supplied in kit) to a Sync Input on the RDi 20. A precision summing amplifier
(internal to the RDi 20) combines the incoming composite signal with the internally generated RDS
waveform to produce the final output. The RDi 20 RDS Output (which is now the full composite signal
including audio and the RDS subcarrier) is connected (via BNC Cable 947-0020 supplied in kit) to the
main program input on the FM Exciter. In Loop Thru operation, a passive bypass relay internal to the
RDi 20 allows the composite signal to pass thru to the Exciter should the RDi 20 be powered off.
In either case, it is necessary to adjust the RDS signal level to produce an appropriate (approximately
3%) final injection level. See the RDS Output Level Settings section of this manual for further
information on adjusting signal levels.
