The BCM should be wired correctly, without loose connections, and +12 VDC connected at pin 35.
A RED LED will indicate that the BCM is powered and receiving 12 VDC. The DC is connected to the BCM with
4 wires in the upper right corner of the board: ground, receive, transmit, and 12 VDC power in (Gnd, RX, TX,
and +12VDC).
The toggle switch on the BCM corresponds to the dial underneath it. (In the event where communication
between the DC and BCM is lost or the DC is damaged, this switch will enable "manual" functions of the
selected devices) The switch and knob are used for Motors 1-5 (which could include slide outs, and awnings)
The DC will be mounted in a "all access" area near the entrance. On the DC, hold down the Power ( )
button for 5 seconds. After a moment,the Passcode Screen will appear. Enter your Passcode . If this is the
first time the DC has been powered on, an End User License Agreement (EULA)screen will appear. Upon
accepting the EULA, the Enter New Passcode screen will appear. Enter your new passcode twice.

The DC will now bring up the Home Screen. If the Floor Plan has been loaded, all the available watertanks ,
battery voltage, and 3 "Hotkeys" will appear. The hotkeys will turn on the Water Pump, Water Heater, and
Interior lighting groups.
The DC has 4 physical buttons underneath the LCD Display. These are (from left to right) the Power, Pages,
Home, and Return buttons. To power on or off the DC, hold the Powerbutton down for 5 seconds. Touch the
power button, and the DC will activate (if powered on). The Pages button will cycle the pages on the DC;
from Home, to the Functions page, to the Menu page. The Return button will take you to the previous page.
Press the Pages button and observe the Functions Page. Here all the available functions for the RV will be
listed. Cycle each function and ensure it works smoothlyand corresponds to the correct device. Ensure all
the Home Screen "Hotkeys" actuate/turn on the corresponding devices.

When turning on the Water Pump, open the Kitchen Faucet and listen for the pump to turn on. The Water
Pump is pressure controlled and will cycle based on demand. During this time the Water Pump button will
stay highlighted. The Interior Lights button will turn on all interior lights and stay highlighted when the lights
are on.
Pressing the "Pages" button a second time will take you to the Menu Page. The Buttons on top of the page
represent (from left to right): the Function List Menu, Connected Devices List, Bluetooth Menu, Password
Menu, Settings Menu, and Information Page .
Time to pair a device. Select the Bluetooth Menu ( ).
Selecting the Water Heater button will offer 3 settings: Electric, Propane, or Both. When the desired
selection is made, the Water Heater button's label will change to reflect the selection and stay highlighted.
Select the Water Heater button again to turn it off.

The Pairing Screen will appear:
On the iOS Device, go to Settings and turn on Bluetooth.The iOS device will automaticallybegin broadcasting
a signal and it will show up in theUnpaired Devices list. Selectthe device. Onboth the iOS device and the DC,
a Pairing Request screen will appear. Accept the paring request. The DC will now be listed in the iOS Device's
Bluetooth menu (i.e.: JENSENDC05E1F7). Select the DC on the iOS device, it will show "Connected" on the
device's Bluetooth list, and the iOS device will show up in the DC's Paired Devices list. Now open the iN-
Command App on the device. It will pair and show the Home screen.
iOS (Apple) Device
Page 8

The Android Devices pair a little differently:
When the Pairing Screen is open on the DC, ensure that Bluetooth is functioning on the Android device, and
open the iN-Command App. Select the Menu button in the Android App and then the Bluetooth button. On
the DC press Discover and on the Android device press Scan. The BCM (i.e.: JENSENDC05E1F7) will show up in
the Android's Unpaired list. Select the DC. A Pairing Request will show up on the DC and the Android device,
accept both. The DC will now appear in the Android's Paired List with yellow font (indicating that it is Actively
paired with the DC. There can be more than 1 DC paired to a Android OR iOS device). Select the Home
button, the DC Pairing screen will appear, then the App will show the Home screen.
Android Device
The iOS and Android device Apps need to have the correct floorplan downloaded from the DC to display the
Trailer's functions. On either device (iOS or Android) go to the Settings screen and select the Reset button.
The Reset Menu will appear. Select Floorplan. The functions will populate on the App's Menu screen. Press
the Home button. Tank levels and Battery charge will be listed. Press the Function List button. The Functions
will be listed with an activation button next to them. The iOS or Android Device is now ready for use.
The iN-Command systemcan only be paired to 7 devices 4 Android and 3 iOS)and only 4 of them can be
active (3 Androids and 1 iOS). "Active" meaning they can activate functions and receive data. Apple
programming dictates that only 1 iOS device can be actively paired. To use another iOS device that is paired
to the iN-Command system,simply push the iOSApp's Power button and shut the App down.This will
disconnect thedevice from the BCM withouthaving to go to the iOS device's Bluetooth list and disconnecting
it. The new iOS device will need to have the DC selected in it's Bluetooth settings before opening the App.
3 Android devices are able to be actively paired at one time. If a user wishes to use the 4th paired Android
device, simply use the Power button on the device's App that the 4th device will be replacing. The Android
device will disconnectto allow the other device to be active.

To verify that the Handheld device is connected to the DC, select the Interior Lights button. All the Interior
Lights should cycle with each button press and the corresponding buttons on the DC , and other devices,
should cycle from OFF to ON and vice versa.
Using the handheld device, cycle through all the functions previously tested on the DC. Ensure the DC display
correlates with thehandheld device's. While testingthe handheld device,push buttons on theDC. Lights
should function while using a Motor Function (slide, awning, etc.). Other Motor Functions should NOT be able
to actuate whilea MotorFunction is in use. A "SystemBusy "message shouldappear.
When connectingmultiple handheld devices,connection should be smooth,no other devicesshould be
kicked off, actuation of systems on one device should correspond to the buttons on other devices, and only
the non-motorized functions should be able to be actuated by any device while motorized functions are being
actuated on another.
Troubleshooting
Next, go to the ConnectedDevices List ( ).
The list should contain all Actively Paired devices with the option to "disconnect" them. Ensure the devices
can be disconnected.
Last, let's test the Lock Out feature. Apply +12 VDC to the Lock Out circuit by using a wire with clips.
Attach one end to Pin 35 and the other to Pin 19. This represents the driver of the tow vehicle stepping
on the brake. On the Home page, a Red button will appear with "Travel Lock " on it. All motorized
functions are now disabled, but the Hotkeysand lights will stillwork.
Carefully remove the wire attached to Pin 35 and Pin 19. The Red button on the DC's Home page will turn
light blue with "Unlock" written on it. To unlock the Travel Lock, this button on the DC must be selected.
the Travel Lock cannot be removed with a handheld device for safety reasons.

Troubleshooting
Troubleshooting The iN-Commandsystem is pretty painless. The BCM and DC simulate all the lights, gauges,
and switches on the old control panels. The BCM Pin Vales portion ofthis guide will clear mostissues.
Basically, if the BCM does not have the desired voltage, or signal input, it will not be able to function or read
tanks correctly. Also, if the BCM has the correct output voltage or signal , but nothing is functioning, the
problem lies in the wiring leading to the malfunctioningcomponent or thecomponent itself.
Any issues that are related to iN-Command that cannot be cleared using the above list will be tied to the
BCM and DC hardware and software. Careful inspection of the BCM will need to be done (possibly blowing
the BCM board with air to remove any dust ,debris ,or conductive material). If the BCM looks clean and
undamaged (without burnt or cracked components) with all the wires secure and not touching each other,
troubleshooting the program is needed.

Above is the Water tank sending unit. The sending unit runs on 7 VDC supplied by the BCM. The 7 VDC
signal runs to a sensor embedded into the side of the water tank. The 1/3, 2/3, and Full sensors are then
aligned in an ascending diagonal line from the 7 VDC sensor. The "To Tank Input" line runs to the BCM
and terminates at Pin s 1-7 depending on the tank. When water or waste starts to fill the tank, it contacts
the 7 VDC sensor and the 1/3, 2/3, and Full sensors. The Voltage travels through the 1/3, 2/3, and Full
sensor leads to a resistor bank, then out the red wire to the BCM. If the BCM is not receiving the correct
voltage (seen on Page 4 BCM Pin Values/Tank Levels in the Notes section) on Pins 1-7, it will not reflect
the correct tank level.
Should the incorrect voltage be coming from the tank, there could be debris on the sensor (for the Gray
and Black tanks) , the line to the 1/3, 2/3, or Full sensors are not terminated correctly, the sensorsare
not installed at the desired angle, or the sensor is bad.
