Diagnostics Overview 

 
The  Mini4  Video  Input  and  Output  boards  have  been  designed  to  include  hardware  and  firmware  for 
monitoring various real-time parameters of interest on the boar.  This capability is accessed via a black3-
pin Phoenix connector on the right side of the board that carries bi-directional RS-485 telemetry to/from 
the  monitoring  PC  to the  Mini4  boards.    The  diagnostics  modem  will  typically  be  used  in  conjunction 
with a user-supplied PC on the surface, which has been loaded with PRIZM Modem Monitoring software 
– PMON II. 
 
The  Diagnostics  feature  does  not  require  the  use  of  an  RS-485  channel  in  the  multiplexer  system  for 
connectivity  between  the  topside  Diagnostic  PC  and  the  remote  multiplexer.    The  Diagnostics  for  the 
Mini4 TRANSPARENTLY carries the local and remote diagnostics over the fiber optic link. 
  

  NOTE: The diagnostics feature in no way interferes with normal operation of the Mini4 boards 
– it is not necessary to be running the diagnostics software for the Mini4 boards to work.

Communications Hardware

 

 
The  diagnostics  capability  is  accessed  via  the  3-pin  RT+/RT-  connector  on  the  black  3-pin  connector, 
which provides the RS-485 connectivity to the on-board processor for diagnostics communications.   
The user is required to communicate with the modems of the system via RS-485. A typical installations  
is shown in the following drawing.
