13. DIGITAL INPUTS BACKPLANE R763378
13.1 General Info
Introduction
This module connects Input Selector 2 (R763851) and the two Digital Input slots with Input Selector 1 (R763850). It also gives power
to the Controller (R7638858) and the Communication Interface (R763766). It receives the standby I²C signals from the Controller
and routes them through Input Selector 1 to the Power Backplane (R764239). These signals are used by the Switched Mode Power
Supply (R764349). The IR signals from the front and rear IR receivers are routed from the Power Backplane, through Input Selector
1 to the Communication Interface. The power supply voltages can also be monitored on this board through led's D5 to D11.

13.2 Power Supply Monitoring
Power supply voltages monitoring
The available generated power voltages are monitored by a specific Green LED on the digital input backplane. To view the LEDs,
remove the SDI input module.
