The PIRA32 RDS encoder is a result of more than 9 years experience collecting and meets requirements of most regional, local, RSL, LPFM and other medium- and small-coverage radio stations. It’s also highly suitable for service and development purposes.
Fully digital concept and uniquely effective design ensures high reliability, excellent signal characteristics and gives the user many advanced features while maintaining low acquisition costs. We can say the PIRA32 brought new standard to this branch. It's not a random that couple of manufacturers around the
world implement the PIRA32 in their transmission systems.
- Fully dynamic stand-alone RDS encoder
- Excellent spectral purity, direct digital RDS signal
synthesis, oversampled; tested for broadcast standards compliance
- RS-232 control interface based on set of simple ASCII
commands; OS independent, no driver required, especial for developers and experimental
natures
- Control software includes powerful Windows GUI application and HTML based system;
remote control capability
- Firmware updates for free
- Addressing feature - independent or common control of
up to 255 units in a network
- Amazing text features
- Advanced weekly scheduling
- Bypass relay, high reliability
- External TA and Program switch
- Switchable MPX loopthrough
- Internal real-time clock incl. backup battery,
showing real-time also as PS
- No special 19 kHz input needed - pilot tone carefully
recovered from MPX signal
- Digital 57 kHz phase locked loop - rock stable RDS
subcarrier in all cases, the PLL will never lock to a pilot frequency outside the
functional range
- Easy and fast set-up

Total text capacity:
- 25 kB - Equivalent to more than 3200 PS. Send text messages without
any space limitations!
- 100 text messages up to 255
characters each sent as RT, dynamic/scrolling PS or both. Manual
or automatic switching.
- Four modes for dynamic/scrolling PS transmission at
selectable speed, incl. word alignment and one-by-one character scrolling.
 All features and its use are described on 47 pages of the pdf manual.

| How to
connect the PIRA32 to a computer? |
The RDS encoder can be connected to a computer via USB adapter or
standard serial lap-link cable terminated by CANON D-SUB female plugs.
Use this description if you wish to make the cable
yourself.
As a next step, download the Magic
RDS 2 control software and you can start to use the RDS encoder at once.
The RDS encoder can be also controlled from
non-Windows operating systems (Linux, MS-DOS, ...) using any RS-232 ASCII terminal. The
command set is easy to learn and gives full control over the RDS stream. It's a strong
tool also for developers. You can find detailed description of
this advanced use in the manual.
Bidirectional interface provides all info about the
RDS encoder services status even if it's installed in neighbour room, abutting building or
on a transmitter site in mountains. Ethernet connection is supported by the control software as well.
For more information and set-up details download the manual.
