GPS In
The 6-pin mini-DIN connector is used for GPS connection. When a valid
GPS source is connected and satellite lock is achieved, ProTraXX will use
the GPS time to set the system clock once an hour. While using GPS to sync
the system clock, make sure the time zone and daylight savings time mode is
properly set on the unit. The ProTraXX accepts a standard NMEA-0183 data
stream at 4800 baud.
Note: NTP time update must be disabled for GPS time updates to occur.
NTP can be enabled/disabled from the front panel menu.
Microphone Input
This is a 5-Pin female XLR connector used to connect a microphone and
push-to-talk(PTT) switch. The ProTraXX can route the microphone input to
any channels or group of channels. See the section on
“Microphone
Paging”
for additional details.
