[h3a]JHub System [/h3a]

[accordion title=”How do I charge my tablet if the battery in the van is flat and we don’t have any Mains power?” style=”style3″]

There are multiple ways to charge your tablet. Depending on your vehicle type, most new model cars are fitted with a USB port – your tablet can be charged via this. Alternatively, you can use a Power Bank (not supplied) or a 12V to Micro USB charger (not supplied).


[accordion title=”How secure is my JHub System? Could anyone “hack” into it?” style=”style3″]

The JHub is fitted with a unique control node (ControlNode101) that is designed to pair with your tablet only. For any device to gain access to this control node they would need to have access to the unique Bluetooth code provided to you. PLEASE KEEP YOUR CODE IN A SAFE SECURE PLACE.


[accordion title=”I have deleted the JHub App by mistake – What now?” style=”style3″]

Information coming soon


[accordion title=”Which media cards are compatible with the JHub Tablet?” style=”style3″]

Micro SD cards up to 64GB. FAT32, NTFS & exFat format.


[accordion title=”How do I add more apps to the JHub Tablet? ” style=”style3″]

Applications are available via the GooglePlay Store or Apple iTunes.


[accordion title=”Can I load files onto my JHub Tablet?” style=”style3″]
Connecting via USB

  • Connect the JHub Tablet’s USB charging cable to a spare USB port on your laptop or PC. *Note that the JHub Tablet mayl not work with Apple products.
  • Connect the other end of the cable to the USB port on the JHub Tablet.
  • If the JHub Tablet is powered-off, the screen will display a charging icon. If the JHub Tablet is powered-on, the battery icon in the top right corner of the screen will display a charging symbol.
  • Once connected you will be able to navigate to ‘My Computer’ and view the tablet as a removable device, from here you will be able to drag and drop files.


[accordion title=”Can I operate the van’s controls from the ‘Control’ screen as well as the ‘Home’ screen? ” style=”style3″]

Yes, you can access all of the controls from both screens.


[accordion title=”Am I getting charged for all this data?” style=”style3″]

The JHub App does not use data, everything is controlled and displayed via Bluetooth. Consequently, your JHub Tablet is not connected to a SIM card or mobile contract, relying solely on Wi-Fi to access any internet functions.


[accordion title=”Can I connect to available Wi-Fi connections using the JHub Tablet? ” style=”style3″]

Yes, the tablet has an inbuilt Wi-Fi adaptor.


[accordion title=”How close do I need to be to the caravan for the Bluetooth to work? ” style=”style3″]

Since the Bluetooth connection is going thru a few walls deally you should be within 20mtrs or less of your device.


[accordion title=”Does the tablet need to be secured prior to any trip? ” style=”style3″]

The JHub’s dock is designed for travel. But in the case you find yourself on a very bumpy road, perhaps you’ll want to take it down and secure as you would with any other valuables.


[accordion title=”Who do I contact for Customer Service issues relating to my JHub & J35 System? ” style=”style3″]

You should contact the service department at the place you purchased your caravan.




[h3a]Jayco FAQs [/h3a]

[accordion title=”Is the ST35 a Smart charger?” style=”style3″]

Yes, the ST35 is a smart charger and maintains batteries through float, equalise, store and trickle modes


[accordion title=”Can I add a generator?” style=”style3″]

The type of generator used will impact on how the ST35 works. Consult your dealer for approved generators


[accordion title=”Is the ST  User settable (for example trickle charge rate)?” style=”style3″]

The ST Series has been custom designed according to manufacturing specifications and as such is not user settable.


[accordion title=”ST – Battery plugged in when not in use – Is it safe to leave my ST plugged into 240 V while not in use, and if I can, would it keep the battery fully charged?” style=”style3″]

Yes it is safe to leave it plugged in to 240 V continuously and yes it does act as a float charger and will not overcharge the battery


[accordion title=”ST – My ST unit is not charging my battery. all 12 volt loads are working well when connected to mains” style=”style3″]

1. Check that any isolation switches installed are not turned on (for example battery switch on the Drifter)
2. Check the fuses
3. Contact us for further support



[h3a]ST Series Tips and Common Questions [/h3a]
[accordion title=”What are the allowed installation orientations?” style=”style3″] Only install with the front vertical as shown – Any other orientation can cause overheating and power supply shut down[/accordion]
[accordion title=”What battery types can I use?” style=”style3″] Only use the types listed in the user manual – Warning: use of other types, such as Calcium Lead, NiMH or Lithium, may not charge or may catch fire[/accordion]
[accordion title=”What happens with poor connections?” style=”style3″] All crimps to Quick Connect (QC) connectors must be done properly – a poor joint can overheat and cause fire. Poor joints will also be unreliable and reduce the voltage to the load[/accordion]
[accordion title=”What generators can I use with the ST35-II/ST20-II?” style=”style3″]

Any generator capable of generating a sinusoidal output at 240 Volts and 50 Hz. The generator manual must be read and it must be capable of delivering 560 Watts / 330 Watts at PF of 0.7 for ST35-II/ST20-II. As an example, a 2000 Watts inverter generator that we have checked was only capable of delivering 680 Watts at PF 0.4 to 0.7. This is fine to run the ST35-II/ST20-II, but it would not be able to run anything else at the same time

Generators/Inverters that supply square wave output, will generally have lower peak voltage, this may be too low to run the ST35-II/ST20-II

[accordion title=”What can I connect to the AUX DC in?” style=”style3″] You can connect any DC source that is 14.8 Volts max, 20 Amps max (ST20-II) 35 A (ST-35-II). This input connects via an isolation diode directly to the fuse panel. There is no current limiting provided for this input. Any source connected to this must be current limited to less than the Battery Fuse rating or the battery fuse may blow[/accordion]
[accordion title=”Can I be connected to Mains and have an AUX supply?” style=”style3″]

There should be no problem operating from both 240 Volts and AUX in as long as the AUX in does not exceed the 14.8 Volts limit defined in the manual. The AUX limit of 14.8 Volts must not be exceeded or damage to internal components will occur

It is possible that the power supply will operate in a hiccup mode if the AUX input voltage is above the voltage that the power supply is trying to regulate at, however this should not cause any problem

[accordion title=”Can I connect 2 batteries to the ST35-II/ST20-II?” style=”style3″] The product has not been designed for the connection of 2 batteries in parallel however as long as they are both the same type and state, the ST35-II/ST20-II will see multiple batteries as a single battery[/accordion]
[accordion title=”How long will it take to top up my battery?” style=”style3″]

It usually takes a similar time to charge the first 80% as it does to charge the last 20% of a lead acid battery

The time depends how deeply discharged the battery and charge current. A 120 Amp hrs battery connected to an ST20-II could take around 10 hours to reach 80% charge and another 10 hours to reach 100% full charge. So if it was at 60% full charge, it would take about 2.5 hours to reach 80%, then another 10 hours to reach full charge

Use the Setec BMS-001 battery monitor to keep track of your battery status.

[accordion title=”What battery maintenance do I need to do?” style=”style3″]

Sealed batteries do not require any cell maintenance. Serviceable types require fluid levels to be maintained

All batteries should be regularly inspected to ensure:
• Terminals are clean
• Connections are tight and secure
• The battery is not cracked or deformed

Keeping a battery at 20 °C and not deep cycling (discharge only to 70%) can improve your battery life by up to 5 times longer than high temperatures (40 °C) and deep discharge (below 30%).
Always check battery manufacturers’ maintenance and operations for maximum battery life

[accordion title=”Fuse Replacement” style=”style3″]

Replace fuses only with the recommended fuse rating and type. – Using the wrong fuse can cause over heating of the fuse board

[accordion title=”EMI Considerations” style=”style3″]

• To reduce impact of electrical noise
• Keep wires runs short
• Don’t allow big loops to form,
• Ensure all connections are good quality and wire size used is appropriate.
• Route wires as far away as practical from TV and Radio antennas.
• All wires from and to the power supply can be considered antennas,

Following these simple rules will reduce the size and effectiveness of the antennas
