Receiver Description
Position
Computation
Screen
From the Receiver Identification screen, press the Scroll
button to access the Position Computation screen. This
screen displays the latitude, longitude and ellipsoidal height
of the position currently computed by the receiver. If the
receiver is a base, the displayed coordinates are set ones (not
computed ones) representing the reference position assigned
to the base. See example below for a rover.
The upper line contains the same information as in the upper
line of the General Status screen.
A new press on the Scroll button will take you to the ATL
Recording screen (see below). If however the receiver is fitted
with a radio receiver or is connected to an external radio
transmitter, an additional display screen will show up before
pressing the Scroll button takes you back to the ATL
Recording screen.
The possible two screens show the current radio settings:
• First line: Serial port used, “Rx” for radio receiver or “Tx”
for radio transmitter, radio type (U-Link, PDL, etc.). Extra-
parameter for “Rx”: Power status
• Second line: Channel number, carrier frequency
• Third line: Protocol used (Transparent, Trimtalk, DSNP,
etc.), airlink speed
• Fourth line: Squelch setting (medium, low, high). Extra-
parameters for Rx if a Pacific Crest: “FEC” if forward error
correction enabled, “SCR” if scrambling enabled.
Modulation type (GMSK, 4FSK). The fourth line will be
slowly scrolled to the right if four parameters have to be
displayed in the line.
