CRS-180 Switch DIP Settings

The 'Switch Conditions' DIP switches are set depending upon the type of Tx or Rx
traffic conditions resultant of switchover. Some modems have additional settings or
alarm masks that affect conditions – refer to the pertinent modem manual for
detailed explanations.
Figure 3‐3 shows the DIP switches for setting 'Switch Conditions' on the Antenna Side of the
CRS‐180 70/140 MHz IF 1:1 Redundancy Switch. Table 3‐1 illustrates the 'Switch Conditions' DIP
switch settings that determine switchover functionality for a given redundancy configuration.
