2  INTRODUCTION 

 
 
The  RF  Central  RFX-RMT-II  SD/HD  transmitter  is  designed  for  permanent rack-mounted 
applications, such as an ENG truck/vehicle or fixed link applications.  The unit features a 
comprehensive range COFDM modulation formats (QPSK, 16 QAM, and 64 QAM) and the 
MPEG  coding  formats  which  may  be  set  directly  from  the  front  panel.  The  RMT-II  offers 
significant  additional  features  including  ASI  and  component  video  inputs  together  with  4 
audios (analog, AES digital or SDI embedded).  
 
The unit may be switched between SD and HD encoding profiles. 
 
The  unit  may  be  controlled  in  three  ways:  by  remote  control  (RS232  /  RS485),  by  front 
panel  key  pad  and  LCD  display  (comprehensive  functions),  and  by  front  panel  switches 
(frequency and power only). 
 
MPEG  encoding  parameters  are  set  from  16  pre-set  conditions,  with  an  additional  user 
presets which allows all parameters to be individually adjusted. 
 
The  transmitter  comprises  a  self  contained  19”  inch  rack  mount  (2  ‘U’)  unit  that  powers 
from +12 VDC. 
 
At the receive site, a range of RF Central digital receivers may be used, for example, the 
complementary  RMR  digital  rack  mounted  receiver.  Please  consult  the  separate  manual 
for information detailing the operation of receivers.
