Description:

This document is a guide for system integrators that provides the necessary information for communicating and interfacing with the Capacitive Touch Keypads RV-C. This document includes a description of the devices functionality and full list of supported DGN’s regarding the communication and configuration of the Capacitive Touch Keypads.
The Capacitive Touch Keypads communicate via CANbus utilitizing the RV-C protocol. 4-pin Minifit connectors are used as the main connector. It is used for communicating on the RV-C network and providing power and ground to the device. The Minifit pin definitions are listed below:

Pin	Description
1	CAN H
2	CAN L
3	GND
4	PWR

The RV-C protocol defines the data rate for all transmitters at 250 kbits/s, with a sample point rate being between the range of 85% to 90%. For more information on the physical layer of an RV-C network please refer to the RV-C specification provided on the RV-C website.

Proprietary Messages

The Capacitive Touch Keypads offer parameters that are configurable via the RV-C network. This allows installers or users the ability to make changes to their module as they feel necessary. Byte 1 of the proprietary messages determine what function is being performed. 0x00 and 0x01 allow the reading and writing of these configurable parameters, respectively. The keypads can help users identify individual buttons by flashing their backlights. This feature makes the configuration of the keypad buttons easy. Byte 1 as 0x02 and 0x03 starts the identification of a button and stops the identification of a button, respectively. Byte 2 specifies which input is to be read from/written to. 0x00 represents module specific parameters and 0x01 – 0x0A specifies a particular input button. Byte 2 is also responsible for saving configuration changes. 0x0B will erase the flash and save the new configuration values that are present in the RAM. 0x0C will undo any changes made that have not been saved to flash. The tables below show how to access the parameters of the module or a specific input and a description of how the parameter functions.
Note: Any changes made to the configuration must be saved to the device using the designated proprietary message or changes will be lost upon power cycle.
Byte[2] = 0x00:

Byte[3]	Limits	Default Value	Description
0x00	250 >= Val >= 1	0x01	Module Instance is the instance of the Keypad on the RV-C network.
0x01	Val = 4, 6, 8, 10	0x0A	Number of Inputs defines how many buttons are present on the Keypad.
0x02	100 >= Val >= 10	0x64	Backlight brightness (%) during daylight conditions when button is ON
0x03	90 >= Val >= 0	0x00	Backlight brightness (%) during daylight conditions when the button is OFF
0x04	100 >= Val >= 10	0x32	Backlight brightness (%) during dark conditions when the button is ON
0x05	90 >= Val >= 0	0x0A	Backlight brightness (%) during dark conditions when the button is OFF
0x06	1 >= Val >= 0	0x01	Use Ambient Sensor – if true, the keypad will use the on-board ambient light sensor to detect daylight and dark conditions. Else the keypad will rely on other devices to report current conditions.
0x07	100 >= Val >= 10	0x32	Ambient Light Threshold is the current light conditions expressed as a percentage at which the backlight will toggle between day/night mode.

Byte[2] = 0x00 – 0x0A: 

Byte[3]	Limits	Default Value	Description
0x00	250 >= Val >= 1	0x00	Target Instance is the instance of the device that will be controlled by the input button.
0x01	8 >= Val >= 0	0x00	Target Type is the type of device that will be controlled by the input button. See table below
0x02	1 >= Val >= 0	0x00	Output Dimmable – if true, the target device is a dimmable device.
0x03	1 >= Val >= 0	0x00	Slide Direction – only applicable to slideouts and awnings 0  – Extend 1  – Retract

Target Device Types:

Value	Device Type
0x00	Disabled
0x01	Digital Input
0x02	DC Load
0x03	DC Disconnect
0x04	Slideout
0x05	Water Pump
0x06	Water Heater
0x07	Awning
0x08	DC Dimmer

The keypad also offers feedback and control of the button backlights via RV-C network using proprietary messaging. This allows integrators the ability to indicate statuses to each button independently when using a passive architecture. Byte 1 of the proprietary message values of 0x00 and 0x01 allow the reading and writing of backlight statuses respectively. Byte 2 set to 0x0D represents a read/write of a passive input. Byte 3 identifies which button position to read/write to. Byte 4 represents the status of the output that the input button drives. This will update the backlight appropriately. Below are examples of proprietary requests:

Windows Graphical User Interface (GUI)

The RV-C Keypad GUI is a Windows-based tool that allows integrators to configure devices to their exact needs.
This tool can configure all the parameters that are mentioned in the table above. Please note:

• When the ambient sensor on the RV-C keypad is disabled, the device will need to retrieve ambient light information from the VEHICLE_ENVIRONMENT_STATUS DGN to adjust the device’s brightness levels.
• When identifying an input button, all other button LEDs are disabled, and the selected button will flash in a 1Hz pattern.
• The “Save Changes” button must be clicked to push all changes made in the GUI over to the keypad device.
