6 Z-Sensor and Z-Eurocard Operation Manual
[X] External Frequency Reference
The external frequency option [X] allows you to input an external frequency so the
user can synchronize receiver data to an external clock. When enabled, its installation
disables the internal oscillator and use the external frequency input only. This option
is not available for the Z-Eurocard.
This option is not available for firmware version UC00 or older.
[M] Remote Monitoring
The remote monitoring option allows you to use the
REMOTE
.
EXE
to access and
control the receiver via a modem from a remote location.
[F] Fast Data Output
This option enables the receiver to be programmed to output both raw position data
and NMEA messages at user-selectable frequencies up to 10Hz. Without this option,
only frequencies up to 5Hz are available.
[T] Point Positioning
The [T] option allows you to put the receiver into point positioning mode using the
$PASHS,PPO command. Point positioning mode improves the accuracy of an
autonomous position of a static point.
[3] Observables—1, 2, 3
This option determines the observables available in the receiver where:
1—CA code and P-code on L1/L2 (No carrier)
2—CA code and carrier, P-code on L1/L2 (No carrier)
3—CA code and carrier, P-code on L1/L2 and carrier
[J] RTK Rover
The [J] option allows the receiver to act as a rover station that utilizes the carrier
phase differential (both DBEN and RTCM message 18, 19, 20, and 21) data
transmitted from the base to compute differentially corrected positions. This option
requires the observables option to be 3. For RTCM messages type 18, 19, 20, and 21,
the U option is required in addition to the J option.
