From what I understand of the Apoc design, the monitoring right pod contains 3 "special" O2 cells (with no temperature compensation), which are plugged to a complex circuit board for processing their signal. This on-board computer does a bunch of computations, including other stuff, and ends up "displaying" the ppO2 through the PFD, the voice, and later on, wirelessly to the matching computer.
So this is *one*, powerful yet complex ppO2 monitor.
Say I want to add another, fully independant ppO2 monitor: different battery, different (simpler) circuit board, different display. For example, a shearwater or subsea display. Obviously, I can't share some of the existing cells, as they are apoc-monitoring-specific.
What are my options ?
- punch a hole in the counterlung, fit a Draeger P-port and insert a regular P-port holder in there
- the canister head whose picture was posted a while back shows holes for fitting cells. Can I use one of these to install a classical R22, tap a thread somewhere on the side of the head, run a wire through a cable gland exiting from the head and fit a display there ? Is this doable ?
- other options ?
