Arts (Automatic Range Transponder System) Operation; Dcs Type (Normal/Inverted) - Vertex VXR-1000 Service Manual

among the "standard" CTCSS tone list), the
TONE SELECT window will appear, with
the nearest valid CTCSS frequency pre-se-
lected.
Turning CTCSS ON turns DCS OFF (since
both cannot be ON). CTCSS cannot be se-
lected for use if ARTS is enabled (ARTS uses
DCS only).
Note: Turning on the CTCSS Encoder auto-
matically turns off the DCS Encoder, if it was
on.
5-4: DCS Encoder
(Toggles DCS Encoder ON/OFF, Sets DCS Code #)
Press the SPACE bar to toggle the DCS En-
coder ON or OFF, or press [ENTER] to dis-
play the CODE SELECT window, if you are
not viewing it already); press [ENTER] again
to accept the selected code, or press [ESC]
to cancel.
If you know the three-digit DCS code you
want, you can enter it directly using the 0 -
9 keys. When the desired DCS code is dis-
played, press [ENTER] to accept this value.
If you keyed in an invalid code number (not
among the "standard" DCS code list), the
CODE SELECT window will appear, with
the nearest valid DCS code number pre-se-
lected.
Turning the DCS Encoder ON turns CTCSS
OFF (since both cannot be ON). DCS Encode
and Decode are both required for ARTS
operation.
6. ARTS (Automatic Range Transpon-
der System) Operation
The ARTS feature causes the VXR-1000 to
"shake hands" electronically with the user's
ARTS-compatible portable transceiver. If
the portable fails to shake hands with the
VXR-1000 in two successive handshake cy-
cles, the PWR lamp will begin blinking, so
as to indicate "Out of Range" status for the
portable.
ARTS operation requires that DCS Encode
and Decode be engaged. It will not function
using CTCSS nor carrier-only squelch. The
CE-22 Program Software
portable radio's ARTS Mode must be in
complement in order for ARTS to function
correctly.
6-1: ARTS Mode
ARTS operates in one of four modes, de-
scribed below:
OFF: ARTS is not active on this channel. No
handshaking is performed.
RX: The VXR-1000 receives handshake sig-
nals from the portable, but does not
send handshake signals itself. If an out-
of-range condition occurs, the VXR-
1000 will indicate "Out-of-Range" lo-
cally, but the portable user will not
receive an "Out-of-Range" warning.
TX: The VXR-1000 sends out handshake
signals, but does not act on handshake
signals received. If an out-of-range
condition occurs, the portable user will
receive an "Out-of-Range" warning (if
the portable is properly programmed),
but the VXR-1000 will not indicate an
out-of-range condition locally.
TRX:Both the TX and RX functions de-
scribed above are active.
Press the SPACE bar to select the desired
ARTS Mode.
6-2: ARTS Int (Interval)
The ARTS Interval is the amount of time be-
tween ARTS handshake transmissions is-
sued by the VXR-1000. Two selections are
available: 25 seconds or 55 seconds. The
portable radio's ARTS Interval setting must
match that of the VXR-1000 in order for
ARTS to function correctly.
Press the SPACE bar to select the desired
ARTS Interval.

7. DCS Type (Normal/Inverted)

7-1: DCS Type
This command is effective only when DCS
is chosen for squelch control.
A = "Normal" DCS
B = "Inverted" (complement) DCS
Press the SPACE bar to select the desired
DCS Type.
