on the USB-Link, you must cycle the power to the
USB-Link by disconnecting and reconnecting the
USB power supply cable.

trollers on a loop without a CommLink or a MiniLink wired
to the communications loop.
Network - MiniLink or CommLink connection - The slide
switch on the USB-Link should be set to “Network” any time
there is a CommLink or MiniLink wired to the communications
loop.
