2.4 Parameter Module
Each parameter module may consist of the module infrared communication board, module
power board, module button board, parameter board, etc.
2.4.1 Module Infrared Communication Board
The module infrared communication board allows a short delay when powering up the
module and adopts FPGA to enable infrared communications between the module and the
module rack. An ID is integrated into the module infrared communication board. When a
module is inserted in the module rack, the ID is automatically sent to the module rack.
2.4.2 Module Power Board
Some modules have no power board. There are two kinds of module power board:
1. Isolated power board: converts the 12 V DC into a 12 V isolated DC and a 5 V isolated
DC.
2. Non-isolated power board: converts the 12 V DC into a 5 V DC
2.4.3 Module Button Board
There are keys and a LED on the module button board.
2.4.4 Parameter Board
The parameter board is a parameter measurement component, which is the most important
component of the parameter module.
