Convert IU into portable

[WhaT]

Hey guys, the IU unit is connected to the battery of our vehicle. Anyone tried removing it and connecting it to a 6v / 12v battery? I am trying to convert my IU to operate on batteries. Anyone with / without the experience able to help?

How much current does the IU unit take? The actual current that is drawn should be measured when it goes under a gantry. If it's within acceptable limits, we should be able to use a battery holder, the kind seen in clocks and in R/C toys to power the IU.

 

Another concern is that the IU serial number is linked directly to the vehicle registration. Hence by law, it is meant to be a part of the vehicle at all times. Making it portable is going break a number of regulations, no doubt.

 

Also, if you make the IU portable, many people are bound to "forget" to take the IU when they leave home at rush hour. The first few people that the TP catches might get away with that excuse. The later ones may also try the evergreen ones -

 

1) "My dog/cat peed/shat on the IU unit." - You gotta love pets!

2) "My kid/pet-python ate the IU unit" - Just don't keep the cashcard in the IU unit, else it's going to be an expensive meal.

3) "My IU unit was stolen" - The person who steals IU units should be shot for stupidity...

4) "I pawned my IU unit for a couple of tequila shots" - The bar tender should be shot for stupidity.

Btw, TP dont bother where u place ur IU unit...ROV not bothered by it too..Even when i go vicom, they nv mention about it...

[WhaT]

Thx guys for the information.. erm am trying to make it portable for my own convenience. As its kinda troublesome if its mounted on a sports bike.

[PegScraper]

Bro What, I was just joking about it all.

 

One really cool application for the portable IU would be for people who don't pay any ERP on their routes, but still need the IU to enter their season parking lots. When you come to the parking lot, just show the sensor your IU unit, and ride off. Pretty cool. Also if it's in your backpack, it would work under a gantry.

 

All the while keeping your bike looking cool... Good luck bro...

[WhaT]

PegScraper .. no worries. Am okay bout all comments i dun take it to heart. For references only.

 

Any way regarding my post I have already found a solution to it.. thx anyway

the IU has internal batteries, so if the IU is disconnected from the power source for a long period, the internal batteries will be flat. Once they are flat, no amount of charging can resurrect the batteries. I screwed one IU that way too. Now my new IU is also quick connect/disconnect type, but when I remove it from my bike, I connect it to a 12V charger to keep the IU internal batteries happy.

It is not a question of who is bothering who...or whether the authorities didn't say that you specifically cannot remove the IU unit....

 

Using your brains..if there is any...you will realise that if you were to use your two wheeler on Sillypore raods....without the IU unit ..you are simply not being able to travel without restrictions or encumberances that will hamper not only the logical use of your bike but also that it will cause inconvieneces brought upon by yourself by removing the unit!

My IU is under the pillion seat. I rather not risk smashing it to pieces if *touch wood* I crash on track.

 

If your "portable" IU is always connected to a battery pack, then there is no problem. But if you disconnect it from all power sources, then the internal batteries will die.

[Wayang]

so how long can the IU's internal batt last without being connected to a power source ? i've left mine lyin ard for abt a month oredi.. damn~!

Bro [W[hat, care to share your solution???

better get it charge immediately, otherwise you will be $150+GST poorer.

hey bro there is a IU that is using battries. its the big type and got those round tube on the right size of the IU. that one is portable no wire attached! my friend got it at vicom after 3 times of inspection. so the vicom guy exchange with portable ones. i do comfirm with my rov friend then he said you can go down and talk.

The internal is powered by 2 cr123a batts.

 

It's not rechargable.

in tat case.. do i need to do anythin to keep the iu 'alive' ? cos i havent connect it to my bike for abt a month oredi..

[Aalex82]

my bike previous owner take out the iu for a long time..

cos he nv go CBD area or even carpark..

onli for track purpose and touring..

when i take over the bike, i juz install back the iu and it's ready to be use..

since black comet say that the battery is not rechargeable..

even we put it wif a power source, the batt will still go flat..

[BLACK COMET]

U can prevent it from going flat by plugging into a power sources.

 

The 2 cr123a is design to be a secondary power source. The mains being the primary ones.

 

Once it detect the primary power=0, the secondary will come in.

 

It's solder with wires into the circuitry. Lithium once open used, they will have the max life span of 5 years +.

 

So for u guys, If you make it portable, just attach the neccesarry voltage to it. In this case, It's 12 volt.

 

Although it can run at 9V, But at 9 V power at primary, the secondary may or may not on.

 

So, maybe u all standby 2 set battery packs, rechargables one. 1 pack will be in connect all the time. Once flat swap with set 2 and set 1 go recharge lor.

someone mentioned placing the IU inside pillion seat..... How can this be done? How he does it??? Will the IU work if placed inside seat fairings?

It's quite clearly printed that the internal batteries are not "re-chargeable". That is the only batteries inside the IU, and it can last about 5 years. If that's the case, the IU can be detached from it's external power source for up to 5 years, and it will automatically spring back to life when external power is attached. Mine was detached for about 6 months when the IU was about 2 year old, it went dead. Cost me $150+GST for a new one.

 

Just to share.

I did an test with ERP last month. I rode by bike with the IU on but no external power detached. I rode passed a ERP gantry with my cash card inserted, there was no beep or light or camera flash. Within two weeks, I received a registered letter from LTA to send my bike with the cash card for ERP inspection. At the inspection centre, the tech held a portable device to scan my IU (of course the external power is attached now), and he recorded my cash card number on the letter. No fine, don't even have to pay for the toll which I missed.

 

From this test, now I know the internal batteries is sufficient to power the IU to poll with the ERP gantry. With that, the ERP gantry is able to capture the IU's ID.

Actually, you're mistaken. When entering without a power supply connected, the gantry detected a "no IU unit" and snapped a photo of your bike number plate which is what they used to track down to you. The next time, if you have the oppurtunity, take a look at the gantry. You will see a few sets of cameras pointing at your rear number plate.

 

The same method is also used to capture foreign cars without the rental IU entering the restricted zone. They will then be stopped at customs upon exiting Singapore.

If there is no IU, then there will be a $70 fine. I did not get any fine, just a letter for inspection, and not even have to pay the outstanding ERP fee.

haha... my mistake... just found tjis from lta webbie...

 

Qn 35: I have received a Vehicle Inspection Notice (VIN) from LTA, where can I send my IU for inspection?

If you have received a Vehicle Inspection Notice (VIN) from LTA, you would need to send your car to the Appointed Inspection Centres for inspection.

 

VIN will be issued if the gantry detected technical errors due to cash card error, IU error, no supply to IU and communication errors.
