			=Communications=
			RaceCapture/Pro is equipped with multiple CAN bus networks to facilitate communication with various devices. There is a standard convention for selecting which CAN bus to use when connecting devices:
			* '''CAN1:''' Typically used for connecting Engine Control Units (ECUs), including OBD-II interfaces and after-market ECUs. This CAN bus network is often utilized for critical vehicle data and diagnostics.
			* '''CAN2:''' Typically used for extended sensor networks, such as AnalogX for analog sensors, TireX for tire pressure monitoring, and other peripheral sensors. These networks provide additional communication channels for expanded data acquisition and monitoring.

			==CAN Bus Splitter==
			The M8-6P male connector splits the CAN bus networks into individual CAN1 and CAN2 connections using dual M8-4P female connectors. This splitter allows you to connect devices to the specific CAN buses as needed:
			* '''A Connection:''' Connects to CAN1
			* '''B Connection:''' Connects to CAN2

			'''Note:''' The CAN bus connections provide limited power (1A @ 12V) to devices connected to CAN1 and CAN2. For devices requiring higher power, it is recommended to use the Powered Dual CAN Hub. The Powered Dual CAN Hub provides additional power and helps ensure stable operation for connected devices.

			See the [https://wiki.autosportlabs.com/RCP_CAN CAN bus / ECU integration guide] for information on integrating CAN bus communications and CAN channel mapping.

			===Input Mode===
			When configured for input mode, the RaceCapture/Pro sensor input will register a '1' when the input passes a voltage threshold of approximately 3V, and '0' when the input is low (close to 0 volts).

			'''Important Note:''' When sensing large inductive loads, such as the state of brake lights or the on/off state of a motor, it is recommended to connect a '''10K 1/4 watt resistor''' in line with the GPIO input. This resistor helps protect RaceCapture/Pro from large inductive spikes, ensuring the longevity and reliability of the system.

			===Output Mode===
			When configured for output mode, RaceCapture connects that port to the ground and can sink a 1A load per port, which suitable for driving indicators, relays, sending signals to other systems, and driving small devices. [https://wiki.autosportlabs.com/GPIO_Output Click here for more info]

			'''Output Behavior:'''
			* When the port is active, the port will connect to the ground
			* When the port is inactive, the port will be an open circuit.

			[[File:GPIO Output Behavior.png]]

			===Controlling GPIO Ports===
			GPIO channels in output mode are controlled by the logic you create with the on-board Lua scripting capability.
			See the [https://wiki.autosportlabs.com/RaceCapturePro_Lua_Scripting#General_Input_.2F_Output_.28GPIO.29_Functions GPIO section of the Lua Scripting reference] and collection of [https://wiki.autosportlabs.com/RaceCapturePro_Lua_Scripting_Examples Examples].
