Passport I/O Cabin Control
Easy-To-Use Keypad/Display for Marine Air Systems
The Passport I/O Environmental Control Unit is a microprocessor based controller, designed for the
precise control and monitoring of direct expansion and chilled water boat air conditioning systems
from Marine Air. The control is dual voltage, operating at both 115 and 230 Volts, 50/60 Hz. The
display is available in both black and white. In chilled water air handlers, the control is referred to
as AH-Passport I/O.
The assembly has a ground shield to protect against static interference and RF noise. The circuit
board is conformally coated to provide high resistance to external damage or corrosion.
A display cable with gold plated phone-type modular jacks connects the panel to the system
controller. An optional air sensor cable is connected to the circuit board in the same manner. Nonvolatile memory stores all user-selectable parameters indefinitely during operation or any power
failure situations.
Internal self-diagnostic programs provide complete electronic checks of all lights, sensors, keys
and circuits. Fused circuits and M.O.V.s (metal oxide varistors) provide component and board
protection.
The Passport I/O control meets or exceeds applicable ABYC, U.S. Coast Guard Regulations and
