Pressure Module, M-P and Pressure Temp Module, M-PT

Document No. 800 1013-1

5

•

Key for pressure zeroing.

Communication between the module and the central unit is established through RS485 serial

interface.
The power supply voltages to the module are generated in the power supply section of the

monitor’s Central Unit. All electrical connections between the module and the Central Unit are

established via 25-pin D-type connector on the backside of the module.
