NXU-2B Operations Manual
3-8
Radio 1 COR becomes deactivated, so the Radio 2 switches out of the TX mode and
activates its COR output momentarily. This momentary Radio 2 active COR signal
causes Radio 1 to switch momentarily to TX mode, and when it quickly drops back out
of the TX mode its own COR output is momentarily activated. This will once again put
Radio 2 in the TX mode, causing an endlessly repeated cycle where the radios “ping-
pong” back and forth and in and out the TX mode.
The COR Inhibit feature prevents this problem by ignoring any active COR input that occurs just
after the NXU’s TX output command is de-activated. The unit ignores the COR input (whether
hardwired or VOX) only in the specified interval immediately following the inactivation of its
PTT output. The COR inhibit time should be set as long as required to prevent the “ping-pong
effect”, but no longer, or the beginning of a valid audio signal being transferred might be lost.

NXU-2B Dispatch Option
This setting allows the optional WAIS Dispatch capability to be enabled. This is an extra cost
option. Upon purchase, JPS will provide an authentication code which will enable the option
when entered. The code will work only for the MAC address it was created for. Clicking on
Enable will show the unit’s MAC Address. Contact JPS for more information.
