Frequently Asked
Questions
ARSE
Does the antenna have a connector
on it so the seat can be removed from the bike with minimal
difficulties?
The antenna has a 4ft long RG174 coax lead. That should be sufficient in
most cases to allow the seat to be removed and laid alongside the bike
for service operations. If the ARSE control module is placed in an
accessible place on the bike, then the antenna can be unscrewed from it.
An alternative plan would be to use an SMA or SMB connector somewhere on
the coax to give the coax an easy screw or pull a part separation point.
Since every application is different we cannot place an SMA or SMB
connector on the coax because we won't know the optimum position. It is
probably best in most cases to just leave the long factory lead on the
antenna for cost and convenience. If you wish to purchase a connector
for this purpose the critical requirements for the connector are: RG174
coax, 50 ohm. Connectors can be purchased online at companies such as
www.Digikey.com.
You might also need a crimper that can handle RG174 size coax.
Does the antenna have to be inserted inside the seat or can it be
located just under?
This product works using Radio Frequency (RF). Metal acts as a shield
against RF and also distorts RF fields. Placing the antenna close to a
metal plane, such as a fender or metal seat pan, will lower the
transponder read range. If you were to just put it on top of the metal
seat pan the RF range could be reduced as much as 85-95% by distortion.
If placed under a metal seat pan the effective range would probably be
zero due to the shielding effect. On most custom V-Twin applications the
antenna must be inside the seat foam, just below the surface because the
fenders and seat pan are usual made of steel. The antenna needs at least
2 inches of foam between itself and a metal backplane to have decent
range. On some bikes this won't be possible. Oh well, too bad,
uncomfortable seat = no ARSE. Fortunately the majority of bikes have
ample padding. On Sport bikes and most stock Harleys, shielding and
distortion are not usually a problem since the seats are plastic and the
sub-frame is light and small. You could probably get away with just
gluing the antenna under the seat foam of a Sport bike or stock Harley.
The best way to decide is to mock up the antenna placement first and try
it out. If it works, then make it permanent.
I have several bikes; can I have one key work for all of them?
Yes, absolutely. This will need to be done as a custom order but it does
not cost any thing additional. The only trouble with this is if you sell
one of your bikes. That person will now have the key to all your other
bikes. You need to carefully consider this before having this done.
I put both of my ARSE keys in my wallet and now the bike won’t start,
what’s up with that?
The two card key transponders are interfering with each other. When the
control module on the bike activates the transponders, both transponders
are transmitting at the same time causing interference. It’s analogous
to trying to stick two keys in a lock at the same time. They won’t fit.
In this case the card key transponders are both talking at the same time
and the control module can’t decide which one to listen to. It just
sounds like chatter so it ignores both cards. Just place one card key
transponder in your wallet. Leave the other in a safe place in case you
lose one.
What is the range of the card transponder?
There are a lot of factors that determine the range of this device. In
general with 2” of foam between the antenna and any metal, you should
get about a 12” dome from the center of the antenna. There two very good
reasons for our short range system: Safety and Security. If we provided
several feet of range, there is a possibility that a small child could
be playing with the motorcycle controls while a parent has their back
turned and accidentally start the engine. Or someone could quickly hop
on your bike and take off on it before you had a chance to react. We
created a system where the operator needs to be seated and in control of
the motorcycle before it can be started. You can always lay your wallet
or card key transponder on the seat and start the bike when performing
maintenance, tuning or service.
If I get off my bike with my card, will the bike shut off?
No, the transponder card is only used to start the bike. The bike will
stay running if you get off and walk away. As long as you do not use the
kill switch to kill the motor, you will not need the card to start the
bike again. Once you hit that kill switch the bike is immobilized. It
can only be started once again with the correct transponder card
present.
What if I lose my card?
If you’ve lost your card, you’ve probably lost your wallet too! In that
case you’ve got bigger problems than just starting your bike. At least
the ARSE has let you know to head back in the bar and find your wallet.
If that’s not the case, then you can either use your spare card to start
your bike or you can call BulletProof Electronics at (941) 708-3444 to
have a replacement card sent overnight to you. Replacement cards are $80
retail plus shipping and handling. You’ll need to have filled out your
customer registration and sent it in to BulletProof or know the serial
number of your unit. Each unit has a different ID code so we’ll need
some way to identify you or the bike. We will not send out replacement
cards unless we can directly identify you as the owner.
