Blackhawk USB560m (need help with missing DC Adapter)

ZiYi Chen

Hi All,

I apologize that this question is not strictly/entirely related to CCS. I ran out of places to ask this question.

I have a used Blackhawk USB560m which I would like to use with my BBB. However it is missing a DC Adapter. Could someone please tell me what is the center polarity of the barrel connector? Is it center positive?

I was unable to find this in the Blackhawk documentation, but I have been using a used Blackhawk USB560m with a replacement center positive power supply.

[I had the same problem in that the original Blackhawk DC Adapter was missing]

Hi,

I can confirm Chester's remark. The adapter I have for a BH-USB560m is center positive.

IIRC it is an EIAJ-II (terribly difficult to find). Reference:
en.wikipedia.org/.../Coaxial_power_connector

Philmore also manufactures them as DC Power Plug model 240.
