QHY16200A
12V power ports
These two ports are connected in parallel, so you can either one of these two as power input
port and use the other one as a power output port for other devices that need 12V power
supply.
USB type-A ports
These two ports are USB expansion ports connected to the built-in USB hub, you can use it to
connect with guide camera or other USB devices. This two ports can output 500 mA current. To
reduce the power load of the internal circuit, it's recommended to reduce the use of current.
QHY A series Cameras have a USB hub board in them. And these two USB type-A ports along with
these two serial ports aforementioned are all branched out by the USB hub board. However, in
some particular condition, it results in conflict and the camera will stop working. For example, in
the condition where there equatorial mount you are using also has a built-in hub or where you
used a USB hub already. In this case, you need to install the USB Hub bypass board (small red-
colored board) included in the package.
For detailed instruction of how to install the USB hub bypass board, please check the content in
the following link.
