The SI board has the following external connectors:
■ 13.8V DC power connector (labelled 12V DC) b
■ system connector (labelled SYSTEM) c
■ serial data connector (labelled IOIOI) D.
The SI board has the following internal connectors:
■ two system interface connectors e (to transmitter and receiver)
■ one DC input connector h, if fitted (from internal AC power supply)
■ one DC output connector i (to transmitter and receiver)
■ fan control connector f (to fan power board on fan duct)
■ temperature control connector g (to temperature sensor on transmitter
heatsink).
For more information on the connectors, refer to “Connections” on
page 65.
