HARRIS CORPORATION M7200VTAC 사용자 설명서
MM-011553-001
The VTAC will transition from XCOV(-TG) operation to the Mobile Radio mode of operation if:
•
The distance traveled by the VTAC exceeds a maximum permissible distance from a reference point.
The maximum distance is configured via programming.
The maximum distance is configured via programming.
The reference point is the location of the V-TAC based on latitude/longitude provided
by the GPS when the V-TAC first transitions into XCOV(-TG), either directly at
power-up, from V-TAC Mobile Radio mode, or from VTAC SOI mode.

Distance traveled is the current location of the VTAC, based on the latitude/longitude
provided by the GPS, from the reference point.
provided by the GPS, from the reference point.
•
The velocity of the VTAC exceeds a maximum velocity threshold in miles/hour. The maximum
velocity threshold is configured through programming.
velocity threshold is configured through programming.
Velocity is based on the velocity information provided by the GPS.
If location and velocity information is not provided by the GPS and the VTAC is in XCOV(-TG) mode,
VTAC GPS Interlock processing is suspended. When location and velocity information is provided by the
GPS, VTAC GPS Interlock processing is resumed, taking the first valid GPS position coordinates as the
location reference point and acting immediately on GPS provided velocity.

This is intended to cover the situation where the GPS is not operational. If the GPS is out of coverage, the
last location and velocity information provided by the GPS and will be deemed useable.

When the VTAC transitions from XCOV(-TG) mode to Mobile Radio mode the VTAC will disconnect
all connected clients.
all connected clients.
When the VTAC transitions from XCOV(-TG) mode to Mobile Radio mode, an audio and visual
indication is provided to the operator. This indication is identical to the indication of the mode transition
based on the external event switch.

based on the external event switch.
When the VTAC is in Mobile Radio mode, the VTAC can return to XCOV(-TG) mode only by the
external event switch or manually via the control head menu.

If the VTAC is in XCOV(-TG) mode and the VTAC transitions to Mobile Radio due to exceeding the
distance and velocity thresholds, the VTAC will not transition back into XCOV(-TG) mode when it falls
back within the distance or velocity thresholds.

Scene-Of-Incident Mode (“SOI”)
SOI mode is user-selectable using the V-TAC’s the “Vmode Menu.” SOI mode provides a local repeater
function with no network connection. It supports two concurrent voice calls, and it supports
communication between other mobiles and portables.
function with no network connection. It supports two concurrent voice calls, and it supports
communication between other mobiles and portables.
When using the SOI mode, both the V-TAC and any connected portable or
mobile radios (the clients) are off the OpenSky network. Therefore,
communications with radios and dispatch personnel on the network is not
possible.

Frequency selection is performed manually from a list of pre-defined channels using the V-TAC’s
“Vchan Menu.” The radio indicates the FCC channel number for each in addition to its alpha-numeric
identifier.
