3.8 Operation With a JPS SNV-12 Voter
The JPS SNV-12 voter has the following differences:
• The front panel and RS-232 “DISABLE” signals are not brought to the rear
terminal block connector of the Voter modules.
• The front panel and RS-232 “SELECT” signals are not brought to the rear
terminal block connector of the Voter modules.
Since these signals are not available to the CIB module, the MCNRCD software
will not display the front panel switch / RS-232 DISABLE and SELECT activity
for the SNV-12 voter card.
3.9 Operation With a Doug Hall 4RV/2 Voter
The DH 4RV-2 voter has opto-isolated inputs that allow the voter to work with
signals that go below ground (negative). These signals may be present when these
voters are used with positive ground equipment, such as microwaves. The CIB
module only functions properly with signal levels which are NOT below ground.
CAUTION
Do not operate a CIB module with any system that has signal levels
that go below ground level!
Damage to the CIB module can result and will void the warranty.
