Header Pin-out

<P style="MARGIN: 0px">Can anybody help me with the identification of the Pin-out and some information on the headers that accept the Encoder Module on the AX2250.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">(1) Is this information available anywhere?
<P style="MARGIN: 0px">(2) Is there a Functionality Description of each pin on those Headers?
<P style="MARGIN: 0px">(3) How does one identify what is pin (1) and pin (10) on each header?
<P style="MARGIN: 0px">(4) Is one of the Headers used for mechanical support rather than providing connectivity to an Encoder module?

<P style="MARGIN: 0px">Is there anybody in Tech Support who can help?
<P style="MARGIN: 0px">I have had no response from my direct enquiry to Tech Support. I would be happy with a response that said "we do not know!" or this is "information that we do not wish to publish" accompanied with an acceptable reason!

<P style="MARGIN: 0px">All the information regarding the connector pin-outs, is in the user's manual. Manual is at <A href="dev.roboteq.com/dev1/download/ax2550man17-020105.pdf" target=_blank>dev.roboteq.com/dev1/download/ax2550man17-020105.pdf

<P style="MARGIN: 0px">Pratically any optical encoder can be used. We recommend the US Digital products (<A href="www.usdigital.com" target=_blank>www.usdigital.com)

<P style="MARGIN: 0px">Many thanks for your response!
<P style="MARGIN: 0px">The manual gives the pin-out for the 8-Pin RJ45 connector.
<P style="MARGIN: 0px">This with regret is not the information I need.
<P style="MARGIN: 0px">It is the pin-out (pin-in) information on the two "internal" ten pin header pin connnectors on which the optical encoder is mounted that am interested in!
<P style="MARGIN: 0px">I now understand that the 10 pin header that has the apparently through-pin header pins on the Encoder Module is probably the internal firmware programming header!
<P style="MARGIN: 0px">I guess my interest would now be in the second 10 pin header on which the Encoder Module is mounted and connects within the AX2250.

<P style="MARGIN: 0px">If there has been any ambiguity or lack of clarity in my original request, I indeed apologise.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">If there are problems with the provision of this information please communicate with me directly by email. It is important as I have three AX2250s that I wish to utilise ASAP.

<P style="MARGIN: 0px">Sorry for the misunderstanding.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">There are two 10-pin headers on the AX2550 mainboard. They mate in two connectors on the Encoder module.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">The pinout of these connectors is not published and in any case should be of of little help to you.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">The headers bring power, clock and an I2C communication bus to the MCU that is on the encoder module. The I2C is used to get the encoder values from the Encoder module to the main board's MCU.

<P style="MARGIN: 0px">Hi COSMA,
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">Many thanks for this information!
<P style="MARGIN: 0px">By mentioning the I2C Bus you have simplified matters, resolved and answered my query. We have always steered clear of the I2C Bus in our academic developments as we favour a more direct connection - historically hung up on bandwidth I guess.....
<P style="MARGIN: 0px">I have sent you a message and am most grateful for all your help to date.
