BATS AND PORTABLE BATS OPERATION

Setup  Attitude Sensor Setup
This is the System Level Attitude Sensor setup. (Same
as clicking on the Attitude Sensor line in the Project
Tree.)
The pitch and roll signals compensate target position
for vessel motion. The analog inputs [Trackpoint
(USBL)] can accept voltages up to +/-10 VDC. The
normal vessel motion for a positive (+) Voltage pitch is
BOW UP and the normal vessel motion for a positive
(+) Voltage roll is PORT UP. The polarity of the analog
input signals into the TP3 can be reversed and compen-
sated for in the USBL ATTITUDE SENSOR POLARITY
dialog box. Normal polarity for pitching bow up is (+)
and for rolling port side up is (+). The VRU
scaling can also be modified under the USBL
ATTITUDE SENSOR menu. Normal scaling is
0.2 V/degree (+/- 10VDC = +/-50°). This dia-
log also allows the selection of the Compass
Sensor Input to be either from Trackman (PC)
or (TrackPoint (USBL)).
NOTE: For a Remote VRU the normal Voltage
polarity for pitching BOW UP is [+]. The nor-
mal voltage polarity for rolling PORT UP is [+].
The RS232 Format STD W/PR (standard for-
mat with pitch and roll at end of data string)
also outputs data with this same protocol. The
RS232 Format NMEA ORE (NMEA 0183 type
format string that is proprietary to EdgeTech
and includes pitch and roll data at end of
string) is different in that it outputs data in the
same polarity as its incoming voltage. This al-
lows pass-through of signals from remote VRU
to integrated navigation system without modification of polarities.
For the Trackpoint (USBL) “BATS“ there are three types of Attitude Sensors that can be inter-
faced to the system are; Internal, Analog or Serial.
The INTERNAL selection is not valid with BATS at this time.
