USB Device Port [J3]
Do not provide power to DynaWave through both the USB Device Port and UART Port at
the same time. Doing so could present a safety hazard and / or permanently damage the
device and connected equipment. Solution designs should include safeguards against
accidental double connections throughout the device’s lifecycle.
The USB Device port
J3
can be used to provide power and full-speed bidirectional communication with
a USB-capable host. It is a Micro-USB B receptacle designed to mate with a standard connector found on
commercially available Micro-USB B cables. See
on page
for a list of available cables and
accessories MagTek has tested with the device. See section
for further information about cabling.
When powered through the USB port, the device draws a maximum of 350mA in steady state. Solutions
should build in a safety margin that anticipates potential peaks up to 500mA.
Programmers should see section
for cross-references to programming tools
and documentation for communicating via this port.
