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.

1.4 Use Information
A.Elevated operating ambient temperature - if installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
B. Reduced air flow - Installation of the equipment in a rack should be such that the amount of
air flow required for safe operation of the equipment is not compromised. Additional space between
unit may be required.
C. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
D. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used, when addressing this concern.
E. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
F. Top Cover - There are no servicable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE RE-INSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS
emission problems.

Menu 5 - Set Remote mode
Menu 6 - Set RS-485 address
Menu 7 - Set Minimum Auto Switching Mode ON and OFF
Menu 8 - Restore Switch Position in Minimum Auto Switching mode
Save Menu When “R” is selected or when get to the end
Alarm indications appear on the LEDs (see figure 2.2).
All program changes must start with the operation of the Menu/Execute switch and must also end with the
operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed,
none of the changes will take effect. If programming is initiated and no operator action takes place for
approximately 12 seconds (before the final press of the Menu/Execute switch) the display will revert to its
previous status and you will need to start over.
2582-122 Manual, Rev. B Page 12 1/24/22

2.5.2. Power On Settings
NOTE:The last status of a unit is retained even when power is removed.
When power is restored, the unit will return to it's previous settings.

2.5.5 Minimum Auto Switching Mode
Enabling and Disabling
The Minimum Auto Switching mode is enabled and disabled via a front panel menu. The Minimum Auto
Switching mode can also be enabled and disabled via the following M&C command:
{C5x}
Where x=1 to enable and x=0 to disable.
The status of the 2582-122’s Minimum Auto Switching mode setting can be queried by sending the following
command:
{S5}
Which returns {S5x} where x=1 if enabled and x=0 if disabled.
Operation
In the Minimum Auto Switching mode the switch will remain in a backup state after an alarm event - even if
the alarm event that caused the unit to switch has been cleared. The main display will show an “H” under the
BU MODE after an alarm causes the switch to change states while in the Minimum Auto Switching mode. The
unit can be restored to the normal state via a front panel restore command or an M&C restore command. The
front panel restore switch menu appears after the Minimum Auto Switching mode ON/OFF menu only if the
Minimum Auto Switching mode is on. The switch can also be Restored via the following M&C command:
{C6x}
Where x=1 to Restore.
NOTE: The switch will automatically restore - as soon as the alarm event that caused the unit to switch has
been cleared - IF the Minimum Auto Switching mode is disabled either via the front panel setting or by the
M&C command.
