Note:
For the proper operation of the RS422/485
4-wire, the 2-wire modes, as well as the RS232
mode, a GND (Ground) wire must be connected
between the equipment.
USB Connection
One USB 2.0 HS/FS port with
USB type C connector is
available on the SGX 5150 and
can be configured in two ways:
As a USB device (default
setting) where the SGX 5150
can be powered by a VBUS
5V.
As a USB configurable host
where the SGX 5150 can
provide VBUS 5V 0.5A if
powered by a Lantronix
provided wall adapter or PoE
(hardware optional).
