RVP TTY Setups for dual-system support

In RVP, you must define whether to inhibit the trigger when its associated RCP is inactive. Whether or not this is necessary is determined by the radar manufacturer. Respond to the following questions in the mt (general trigger setup) section:

Blank output triggers according to TAG#0: YES 
Blank when tag input is high: YES 
Blank triggers 1:YES 2:YES 3:YES 4:YES 5:YES 6:YES

These questions control trigger blanking based on the TAG0 input line. You first select whether the trigger blanking feature is enabled; and then optionally choose the polarity of TAG0 that results in blanking (consistent with RCP8 setups), and which subset of the 6 user-definable triggers are to be blanked.

Note that for maintenance, RVP10 on the inactive system can be made to generate a trigger by any one of the following techniques:

  • One of the 6 triggers can be set to Blank triggers NO. This could be used to provide a permanent maintenance trigger.
  • Temporarily respond Blank output .. TAG#0: NO
  • Install a physical override switch on one of RCP8 BITE inputs and then, using the control logic, enable the triggers.
