MODEL 2582-122 Switch, 1 for 2

1.0  General
1.1  Equipment Description

The  2582-122  is  a  1  for  2  Switch  with  Backup  Controller  for  downloading  and  storing  user  variable  data 
settings from the active, on-line  agile, IF to RF frequency (to 2.2 GHz) converters and controlling the back-up 
frequency  converter.  The  2582-122  provides  Auto  or  Manual  backup  protection  for  up  to  2  up  or  down 
converters by relay switching of IF and RF from a backup unit to any of 2 on-line units.  The controller in the 
2582-122 monitors alarms and settings of the on-line units and sets the backup unit to the parameters of the unit 
being  backed  up  prior  to  backing  it  up.  The  2582-122  works  with  standard  Cross  L-band  up  and 
downconverters  by  polling  their  monitor  and  control  ports  on  a  periodic  basis.  A  defective  unit’s  inputs  and 

outputs are switched from the failed unit to the backup when a failure occurs either automatically or manually.  
“On-line,” “off-line” and “not used” modes can be programmed for each on-line converter.  Alarms are contact 
closures to ground.  Status of the 2582-122 is via a serial data stream and a contact closure to ground on alarm. 

All  settings  are  stored  in  nonvolatile  ROM  and  on  power  up  the  2582-122  polls  all  units.    Manual  Select  is 
controlled by the multi-function switches on the front panel. LEDs indicate alarm and switch conditions.  The 
unit is powered by redundant power supplies, and mounted in a 1RU rack-mount chassis.
