After playing with the idea for almost 5 years I think I am now ready to buy an Intercom for my old bike (1984 BMW R100RS).
My intention with the intercom is to be able to speak with the pillion rider of course, but mostly it is to have the ability to use the features of the Himalaya (Qtek 2020), including:
• GSM speech (from both rider and passenger)
• Audio (directions e.t.c.) from the Navigator software (GPS Bluetooth connected – so there are no issues regarding the GPS)
• Audio when using it as an MP3 player
I want to connect the intercom with the 22 pin flat connector, because I also want to charge the phone, and do not want to have the troubles of connecting two connectors (round and flat) at the same time.
I have had a look on the page: http://wiki.xda-developers.com/wiki/Connectors. Instead of going for the DIY Car-handsfree, is it possible to connect the pins from the Himalaya directly to the intercom unit? The intercom unit it prepared for attaching phones.
Audio Connections:
As I read the description (and if it is possible to connect directly into the intercom unit) I would connect it as follows (since the microphone and speakers will be connected to the intercom unit, the following is the “virtual” connections through the cable into the intercom unit and onwards to the mic./speakers in the helmets):
Microphone:
Pin 1 – Line in
Pin 5 – Mic. Ground
Right Speaker:
Pin 3 – Left Speaker
Pin 5 – Speaker Ground
Left Speaker:
Pin 4 – Left Speaker
Pin 5 – Speaker Ground
Question:
I am not sure about pin 19 (CAR_ON#), but as I read it, it must be connected to ground (not the audio ground), in order to have all audio input/output come from/to the intercom. Is that correct?
Charging connections:
I will be using a 5V (7805) regulator, and connect:
Pin 20, 21, 22 – + 5V
Pin 16, 17, 18 – Ground (and maybe pin 19 – se above)
Question:
The “Power hookup” digram shows pin 15 (UDC-) should be connected to the ground, along with pin 17 and 18 – but not pin 16.
Pin 19 is connected to +5/6V, but the pin 20 is not.
What is correct in my case – the “DIY Car-handsfree” or the “Power hookup” diagram?
Summary:
Have I overlooked something (forgotten connections/wrong connections)?
Will what I have described work as intended?
Has anyone had any experiences connecting the Himalaya to an MC intercom?
The Intercom:
The intercom I have in mind is an Autocom Active-Rider (kit 3). http://www.autocom.co.uk/
Thanks in advance for your help.
