2 .4 . USB Ope r a t ion
Note that when a Mini-USB cable is plugged into the 900HP RF Modem, communication to and
from the RS-232 interface and the RS-485/422 is halted. USB communications take precedence
over all other interfaces when you plug it in. To restore communication with other interfaces, the
USB cable should be unplugged.
**The Mini-B USB Connector is intended as a configuration port. The RF Modem should not
transmit data when the Mini USB cable is connected.
