the RC4 Decoder?
Mylaps RC4 Decoder is based on the RC3 Decoder hardware
but with updated firmware that detects the RC4 data messages sent by the
Harry and Purcy transponders in addition to the data messages sent by the
AMB Rechargeable and Direct Powered transponders. The RC4 Decoder will
detect ALL AMB and Mylaps RC Transponders.
Will the RC4 Decoder detect non AMB/Mylaps
No. As they are not designed or manufactured by AMB/Mylaps
we don't know why.
How do I upgrade to the RC4 Decoder?
If you have a recent RC3 Decoder then all that is
required is a free firmware update. If you have an older RC3 Decoder or the
previous RC Decoder then you can trade in your old decoder for an RC4
Decoder. Further details of this
How does the RC4 Decoder connect to the Timing
Like the RC4 Decoder the connection is either Serial or
Network. There is no USB connection. the RC4 Decoder requires a 12v power
supply. You can use a USB Serial adapter but you still need a 12v power
supply, either 240v or 12v battery.
Will the Harry transponder continue to be
As long as there is a significant demand for the Hybrid
transponder it will be available.
Why isn't Car ID available on the Harry
The Harry transponder can be detected by the AMBrc and
Mylaps RC3 decoders. These decoders are not aware of the Car ID and so would
not be able to report if two different transponders with the same 7 digit
number were in use. As a result it would not be possible to determine if an
apparent lap time was recorded by one or two transponders. This would cast
doubt over the validity of racing results.
If an RC3 Decoder is replaced under warranty will
it be replaced with an RC3 or RC4 Decoder?
The replacement will be the current RC Decoder which is
the RC4 decoder.
What can I do if my AMB/Mylaps transponder becomes
If the transponder is out of the 3 year warranty period
it can be traded in for a new Harry or Purcy. If in Warranty and it has not
been physically damaged it will be replaced at no charge. If it has been
physically damaged, such as been milled by a Spur Gear or the wires broken
at the body it can be traded in for a new Harry or Purcy. Trade ins and
replacements are usually by return of post. It any transponder becomes
intermittent always check that it is plugged into the receiver the correct
way round and the plug is not loose.
Will current Race Software work with the RC4
Provided the Race Software supports serial or network
connection the RC4 Decoder should work with current Race Software. Check
with your Race Software supplier. All bbk Race Software works with the RC4
Decoder. The Car ID Harry transponders will work with RC4 Decoder and
current Race Software. To avoid two transponders being used to simulate a
single car there is a mechanism to prevent a second Car ID transponder from
being detected for a period after the first Car ID transponder with the same
7 digit number. This timeout is initially set to 100 seconds. It can be
changed via the decoder menu. With RC4 compliant software there is no such
mechanism and the transponder passing will be reported together with the Car
ID. An RC4 compliant update to bbkRC will be available during the first
quarter of 2013.
