Remote Controlling your RV with Lippert's Linc System.



This is a project in-work. I have completed Phase 1, and now it's on to Phase 2 and 3, which I will do over the winter. So you will have to check this page periodically.


After finishing my wireless remote add-on for the Ground Control 3.0 leveling system for my RV, I came to realize that the remote can control additional items, such as your slides, awning, lighting, and other accessories with the addition of a Remote Receiver.



The Linc multi-function remote (current version is the LC358601) can independantly control Lippert's Ground Control 3.0 leveler as well as a 5 to 8 channel remote control receiver (Lippert calls this a Multifunction 5-Output Fuse Mux Receiver). These two systems are completely independant, but both can be controlled simultaneously with the remote. Thus, the only connection between the Ground Control and Fuse Mux Receiver is the link to the wireless remote.



As I did the research for this project, I could not find any sort of comprehensive manual for the receivers. The market for these receivers is basically OEM, but you can also purchase them aftermarket (although there is no bona-fide aftermarket support). In fact, a few times the manuals direct you to your RV manufacturer for wiring diagrams or other information. Not a lot of support for the do-it-yourselfer.

I did have some difficulty with this project due to lack of data, and I almost gave up. For example, Lippert - for whatever reason - decided to restrict the fuse programming feature on the wireless remote (which is required for the receiver to work) - by limiting access with a PIN. And do you think they publish the PIN? NO. They tell you to consult your RV's manufacturer. But what if you are doing this aftermareket, and the manufacturer did not make the system available in your RV. So how are you supposed to do an aftermarket installation?

There are over 8 billion combinations of the 4 digit pin (9999x999x99x9 = 8,900,199,891). Fortunately though, I did figure out the PIN after a couple of hours (more on that later).

So, what does fuse programming mean? I first thought it might be like a microcontroller, where a "fuse" is a link you sever to permanently change a function within the chip. But no. It simply means enabling a channel by attaching a regular ATC autommotive fuse to it.

Selecting the Remote

If you followed my wireless remote for Ground Control 3.0 project here you already know that regardless of the receiver board you buy, you want the Lippert LC358601. It is the latest version and has a fuse configuration capability built into it required for the latest receiver versions. Earlier remotes may not work with the latest receivers as they will not necessarily have the fuse programming feature.





There are 8 different versions of the receiver that "should" work with the Linc Remote. I say should as I have only tested two receivers, so I am not 100% sure about the older receivers. However, assuming they do, here are the receivers:


Part Number
Part Number
5 Channel
5 Channel
5 Channel with Hydraulic Option
5 Channel with Hydraulic Option
8 Channel
8 Channel
8 Channel with Hydraulic Option
8 Channel with Hydraulic Option


  • Hydraulic Option: Adds several switch points for use with hydraulic systems (levelers and/or slides?).

  • Fuse Option: The newer fused versions include 4 on-board fuses which can be attached to any motor channel. This is perhaps more convenient than wiring in off-board fuses (which most RV wiring is messy enough without in-line fuses). However, the fused versions do require the fuse configuration panel in the wireless remote.

  • Lighting Channel: provides an independantly fused SPST ON-OFF relay points that toggle on or off with subsequent depressions of the remote function

  • Motor Channel: provides polarity reversing relay points depending on which button on the remote is depressed (Retract or Extend). The function is momentary - the contacts are closed only while the remote button is depressed.

  • IDS part number: There are two part numbers for each board. The Lippert part number, as well as the IDS part number. IDS Electronics (Innovative Design Solutions, Inc) is the original manufacturer of the boards (prior to being purchased by Lippert).


You can usually find the receivers here:

RV Upgrade Store

Of course - especially with eBay, you must ascertain the model according to the above list. I highly recommend the fuse versions (Rev C), however, you can experiment with others if the price is right (especially with eBay). But sometimes the eBay seller might be a dealer getting rid of stock that is still new. I purchased my 8 channel receiver (18570) that was still new for $65 on eBay. So don't be afraid to use eBay, but be sure you know what you are getting.




5 Channel Board Layout (without Hydraulic option)


8 Channel Board Layout (without Hydraulic option)


Detailed description of the board functions:

  • Function plus and minus. These are the connections from the (motor) reversing relays.

  • Light. This is the relay contacts for the light. 12V is present when the light is turned on, and 0V when off.

  • External Switch -. This is the common negative side supply for the three external switch ports.

  • External Switch SW. These are the three connections to the external switches that power the manual switches used in conjunction with the reversing relays.

  • Batt. The 12V battery connection.

  • GND. The negative battery connection.

  • Light Fuse. Protects the Light function.

  • SW3 Fuse. Protects External SW3.

  • SW2 Fuse. Protects External SW2. Note that there is no fuse for External SW1.

  • Fuse 1 thru Fuse 4. Programmable fuses (i.e. program it's connection) for one of the 4 Functions.
  • Antenna. For wireless operation.

  • CAN. CanBus connection for use with MyRV systems.

  • Program Switch. Used to synch programming changes with the wireless remote.

In the most basic wiring diagram, simply attaching a DC motor directly to the function channel will cause it to turn in one direction when the EXTEND button is depressed, and turn in the opposite direction when the RETRACT button is depressed. However, many motor controls (Schwintek, etc) have their own driver board, so this does require a slightly different wiring scheme.


Switching Function Behavior


It will be easier to wire the receiver into your RV's system if you know what happens each time a button is depressed on the remote. The following sequences were the more popular combinations you might find between the programming of a particular channel on the remote transmitter and how that channel behaves. The behavior is different depending on what kind of function you program; i.e. slide, light, vent, door lock, and so on.

Reversing Channel (motor control) Behavior


Motor Reversing Function Behavior. When a Function channel is programmed as a slide control, the following behavior is observed.

  • When the EXTEND button is depressed on the wireless remote for the slide programmed Function channel, Ground is applied to the FUNCTION + terminal and +12VDC is applied to the FUNCTION - terminal. This powers the motor in the direction required to extend the slide or awning (assuming you wired the motor correctly). When the button is released, the FUNCTION - terminal returns to 0V.

  • When the RETRACT button is depressed on the wireless remote, the opposite occurs. +12VDC is applied to the FUNCTION + terminal and Ground is applied to the FUNCTION - terminal. This reverses the direction of the motor. As with the Extend button, releasing the Retract button causes the FUNCTION + terminal to return to 0V.

  • The output of the three EXTERNAL SW terminals is normally +12V. However, when either the Extend or Retract button is depressed on the wireless remote for any function channel, all three External SW outputs go to 0V. The output will stay at 0V for approximately 8 seconds after releasing the wireless remote button, at which time will return to +12VDC. This occurs any time any function channel is activated, not just the one you pressed, and regardless of the channel's function (i.e. slide, light, vent fan). This is an optional, but important safety feature which will be discussed in the generic wiring diagram.


Function Channel programmed for lighting control.


When a Function is programmed in the remote as a light control channel, the channel on the receiver is setup to behave differently.

  • Only a single button will be available on the wireless remote (not an extend/retract pair as when programmed for a slide.

  • When you depress the light button, the Function + terminal for that channel will to +12V. When you release the button, the voltage on this terminal will return to 0V. The voltage on the Function - terminal will not change, remaining at 0V - in other words, it is dormant.

  • The External SW 1, 2, and 3 terminals will go from +12V to 0V when this happens, and remain at 0V for 8 seconds after the button is depressed. This behavior does not change regardless of what kind of device is programmed into the function channel.

This presents a challenge when using a function channel as a light control, as if a light is directly connected to the channel, it will only be on while you are dpressing the button on the remote. As soon as you let go of the button, the light will go out.

What is required is either a light fixture that can be turned on-off with a momentary pushbutton, or an external adapter board that latches the pushbutton action into an on-off sequence.


Light Channel Behavior


Light Channel Behavior. This behavior is limited to the single Light Channel found on either 5-function or 8-function receiver board. It is hard-coded into the system and cannot be changed.

One advantage of this function is that it is available on both the main menu on the wireless remote without having to enter a PIN, as well as it is always the first function in the remote's menu after you unlock it with your PIN.

Simply, whenever the LIGHT button is depressed on the wireless remote, the output toggles from ON to OFF. In the ON state, +12VDC is applied to the Light terminal, and in the OFF state, the voltage on the terminal returns to 0VDC.

There is no change in the status of the External SW terminals when operating the light function.


During my initial analysis of the receiver board, I tried many different combinations; programming a light function in each channel independantly; using a different fuse for each channel, and so on. I was attempting to discover some "magical" combination that might put the channel into a latching mode more suitable for lighting control, but I was not able to find any such feature. Too bad the manufacturer didn't spend the resources in coming up with a fuse programming feature in developing a latching feature instead.


Receiver Board Wiring


Typical wiring scheme



This discussion is generic in nature, and only applies to a directly connected motor. Many slide mechanisms employ driver boards that require YOU to determine the method of connection.

You assume all risk, and accept all liability when wiring a device to the receiver, regardless of motor/controller configuration. My assumption is you are skilled enough to properly determine what actions to take by analyzing the diagrams and behavior of the various functions.

Consider this webpage just a guide for how the receiver operates... and any wiring decision is your responsibility.


Consider the diagrams you see here generic. This is the basic wiring configuration that Lippert provides in their manuals.

Module-controlled motors such as the Schwintek systems may require additional configuration methods, as well as possible adapter circuitry to safely function. I am providing the behavior of the receiver as I have experienced it. Connection is up to you to figure out.




Function (reversing motor) Switch Wiring


The above schematic shows what happens when the Function channel is wired for a standard (i.e. directly connected) motor.

When the remote transmitter is not active, +12V is applied from one of the External Switch + terminals (remember, two are fused and one is not). The three terminals allows some degree of load-balancing.

For example, should there be a motor with high current demands, it will likely work better if it uses it's own External Switch channel. This of course all depends on the types and quantities of slide and awning motors you wish to control. The proper wiring configuration is up to you.

With +12V applied by the External SW terminal, manual control of the slide is possible by using the remote switches on your RV's control panel.

However, when the receiver is commanded to operate a slideout via the wireless remote, 12V is removed from the external switches as the External SW + channel goes to 0V.

Then, depending on which button was depressed (RETRACT or EXTEND), 12V is applied to one of the Function terminals, and GROUND is applied to the other. This causes the slide or awning motor to move in the appropriate direction.

Then, 8 seconds after release of the remote transmitter button, 12V is again applied to the control panel switches by the External SW + terminal returning to 12V.

The action of the External SW + terminal ensures that you cannot short the battery to ground by depressing the EXTEND button on the wireless remote while at the same time depressing the RETRACT button on the control panel. You should obviously never do this, but using the External SW function prevents this from happening.


Light Switch Wiring


The single light switch channel is pretty easy. The receiver can be wired to the light switch on your RV (assuming you can access it). There is no need for connecting the External SW + terminals as the configuration does not present a case where a short across the battery could occur.


Adapter Modules


As stated, Function channel can be programmed for a lighting function. Unfortunately though, this will not work as is as the behavior of the relay is momentary. That is, the switch will be on while the button remains depressed. Therefore some form of latching must be employed to use these channels for lights. Since most of the LED lighting used in RVs do not include that function, I will be developing add on modules that will perform that functionality.


Light Switch Wiring using Function (motor) Relays


In this scenario, the Function Channel output can be considered as a simpe "ON" switch. The latch will convert that ON command to alternate between ON and OFF, in much the same way the Receiver's built-in LIGHT channel operates. Therefore, subsequent operations of the remote light switch will alternate turning the light switch ON and OFF.


Three way Version.


It is also possible that a three way version could be developed so that an "either-or" relationship can be established between the wireless remote and control panel switch. These are options that will be explored with my developement of add-on modules.

I am in the design phase of these add on modules at the present time, and will be releasing videos and construction articles in the near future. I will be updating the website on the progress on the Blog page, and on this project webpage. The difference is on the Blog page, I will provide in-work updates, while the finished modules will be updated on this webpage.

The modules I am designing include:

  • Latching Relay Module (suitable for lights, water pump, etc. anything that can be controlled via relay).
  • LED Dimmer Module.
  • Schwintek Interface Module (if needed).
  • Vent Control Module (if needed).

The LED Dimmer module will provide an enhanced functionality for both LED light strips (such as under your awning) and LED fixtures (such as the main cabin lighting). This functionality will include:

  • Light Latching Function (ON-OFF)
  • Optional Dimming Function (ON-Dim-OFF)
  • Optional Timer off Function (ON-OFF after 2-8hr delay) or (ON-Dim-OFF after 2-8hr delay).
  • Optional Stand Alone operation (no receiver control, but dim and delay from control panel).

I will be using the "by now famous" ATTiny85 microcontroller for these modules, which means you can also program additional functionality into the modules as you see fit.



Fuse Menu PIN

I suppose it now comes down to obtaining the 4-digit PIN for the fuse menu in the wireless remote. The menu allows you to assign one of 4 fuses to one of 4 channels. For the life of me, I do not understand why they even bother.

For example, for the 5-Function receiver, the light channel has it's own dedicated on-board fuse, so you are going to program 4 fuses to 4 channels? Give me a break. Why don't they just dedicate fuse 1, 2, 3, and 4 to Channel 1, 2, 3, and 4. Duh! I would really like to hear a Dave Jones (EEVBlog.com) expletive right now.

True, the 8-Function receiver has 7 channels that must be programmed to 4 fuses, so you have to share them between channels. But why not just add 3 more ten cent fuses on the motherboard and be done with it?

The manufacturer probably spends a significant amount of money on each board for in reality an un-needed function, yet the RV industry won't spend any money to improve the tank monitor systems? Incredible.

Just in case the lawyers do have a legitimate liability concern and my not wanting to be sued, I am not going to tell you the PIN. But I will tell you that Lippert has published the 4 digit PIN on this page of their website (you may have to look a bit to find it, but it's there).



Project Phases

Phase 1 of the project selects the receiver board, wireless remote, and getting the two to communicate - DONE.

Phase 2 of the project adds functionality with adapter boards to control LEDs with a latching circuit, as well as several other type modules. We will also construct an adapter board for a Schwintek controller should one be needed - IN-WORK.

Phase 3 of the project is the physical installation into the RV which will happen in the spring of 2018.
