RDS Applications Supported:
- PS (Program Service Name: your station’s ‘street name’ and/or scrolling song info)
- PI (Program Identification: station ID calculated from call letters in US & Canada, assigned by broadcast authorities elsewhere)
- PTY (Program Type: your station’s format or theme)
- PTYN (Program Type Name: a further refinement of your PTY)
- AF (Alternative Frequencies: yours and your rebroadcast ‘translator’ frequencies)
- RT (RadioText: additional scrolling messaging)
- CT (Clock/Time: sets the listener’s car clock)
- DI (Decoder Information: mono-stereo data flag)
- M/S (Music/Speech data flag).
Flashing Panel Alarms
A PI code is essential to RDS operation. NO PI CODE RDS MUTED will flash and the 704 will not function until a PI code is entered. When the pilot alarm is enabled, PILOT LOSS flashes if lock with the stereo pilot is lost.
An unbalanced/bridging input (BNC) accepts either the complete composite-multiplex stereo baseband signal or 19kHz TTL-level stereo pilot sync from the stereo generator. Maximum amplitude: 5Vpp. The 704 reverts to an internal time base for monaural transmissions.
RDS Output:
Unbalanced, 75ȳ (BNC); delivers the RDS subcarrier (only) to feed the RDS/SCA input of an FM exciter. Output level adjustable from zero to 4Vpp.
Network Port
Network connector (RJ45) accepts multiple IP networking connections; one TCP port and one UDP port.
Power Requirements
+12VDC at 240mA. Two, paralleled coaxial DC power jacks (5.5mm x 2.1mm) allow the 704 to
‘daisy-chain’ with companion INOmini units. A universal 90-240VAC inline switching power supply is supplied.
Size and Weight
- 1.8” (46mm) high, 5.3” (135mm) wide,
- 6.1” (155mm) deep; 4 lbs (1.8kg) shipping weight.
Mounting Options
An optional rack adapter accepts up to
three INOmini modules in a 1U, 19-inch rack space. The INOmini 704 may also be fastened to any convenient surface with two small screws.
Program Audio Outputs (continued):
- Headphone Jack: (¼” TRS) Menu-adjustable listening level.
- LAN Port: (RJ45) LAN connection to local network or Internet provides remote monitoring, control, listening and full SNMP implementation; user-programmable network setup and streaming parameters.
General Purpose I/Os (Plug-In Barrier Strip):
- Inputs: GPIs are ground-seeking logic inputs with internal pull-up to +5Vdc. Programmable to accept momentary or sustained ground to switch functions.
- Outputs: Individual open-collector NPN transistor closures to ground are associated with alarm alerts. Each is programmable for GPO assignment and logic polarity. Outputs sink 100mA, 40VDC max.
