Carrier Board (PCB-001)
Theory of Operation:
This is the main interconnection board in the console. It interfaces to the various modules in the console. This board should be the last
board changed in a console, and only after the remaining systems have been verified to be functional. There might be some
differences in how this board connects to the other modules for the various console SKU's, but make sure that all the connectors are
properly seated and that there are no pinched cables between any of these connections.
Functions/Connectors:
• The COM Board - IMX6 (PCB-002)
connectors between the two boards. Make sure that the spacers between these two boards are properly installed, and that the
board is fully seated in the connectors, prior to installing the 4 mounting screws.
• There are two connections to the
second cable for the 24VDC goes from P6 on the Carrier board to P8 on the MIB board.
Troubleshooting tips:
• The Carrier board does have a USB HUB on it. So failures on functions with some USB tasks (USB reprogramming port, Wireless
connectivity module) might indicate that this Carrier board is damaged, but only after you verify the functionality of the other USB
modules.
• The Carrier board does contain the EDID firmware, which allows plug-and-play setup with HDMI devices (STB-IPTV, STB on the
floor, etc.) since it properly configures the STB output to match our console requirements. Contact Life Fitness service call center if
there are issues on consoles with video / audio from STB's.

is mounted onto this Carrier board as a daughter board, and uses three board-to-board
MIB (PCB-003) board. One cable between P1 on the Carrier board to P1 on the MIB board. The
