Overview
The 2582-324 1 for 2 Switch with Backup Controller provides Auto or Manual backup protection for up to 2 converters by relay switching two IF and one RF signal from a backup unit to any of 2 on-line units. The controller in the 2582-324 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 2582-324 works with standard Cross 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”, “offline” and “not used” modes can be programmed for each on-line converter. Alarms are contact closures to ground. Status of the 2582-324 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 2582-324 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 two 100-240 ± 10% VAC redundant power supplies, and housed in a 2RU chassis
