I/O Bay PCBA
General
The basic I/O bay PCBA connects the rear external connectors to the CPU PCBA via the
interconnect PCBA.There are no active components on this PCBA, rather, all the components are
connectors, ferrite beads, capacitors, and resistors.
With the Capnography option, the I/O bay PCBA is split into two pieces and mounted inside an
extended I/O bay housing that also holds the capnography electronics.
