2.6 Shared pressure probe
Only 4 to 20 mA pressure probes (not ratiometric) can be shared. The
probe can be shared by a maximum of 5 drivers. For multiplexed systems
where controllers EVD evolution1 to EVD evolution5 share the same
pressure probe, choose the normal option for EVD evolution1 and the
"remote" option for the other drivers, up to the fi fth. EVD evolution6 must
use another pressure probe P2.
