4.4 Configuring the Input and Output Parameters
This section describes the configuration of the communication between GAPS and the
external sensors. These parameters are divided in input (4.4.1) and output parameters (4.4.2).
The parameters are in the
INPUTS
and
OUTPUTS
items of
INSTALLATION
menu.
4.4.1
C
ONFIGURING THE
I
NPUTS
The following inputs (
Position
,
UTC
,
Pressure
,
Telemetry
and
Hoisting System
) are
configured here:
Position
Position
data input comprises position, time and date. GPS is plugged directly to the GAPS
antenna or to the BOX. The GPS antenna broadcasts data on Ethernet or serial link.
GPS lever arms are input in the User Interface or in a navigation software but not in both!
UTC
External sensors delivering
UTC
are connected to a serial plug or via the Ethernet network.
Pressure
Pressure
data input allows the computation of immersion (see Appendix H.2). Pressure
comes from a pressure sensor installed on the underwater vehicle or is broadcasted on an
Ethernet or serial link. A pressure offset can be added to the incoming data.
Telemetry
Under
Telemetry
, set the identical configuration than in the equipment that output the
telemetry datagram. Only one protocol
ITS TELEMETRY
is available.
Hoisting Sys.
State of the hoisting system is displayed as antenna status in the
CONTROL
menu.
4.4.1.1
Input Stream Parameters
Below, you find the various parameters that you have to set up:
●
Input
: Choose the
Port
among the
Serial A, B, C, D
and
Ethernet A, B, C, D
ports.
Select
Embedded
(for
Position
and
UTC
) if you use the iXblue GPS. Select
None
if
there is no external sensor.
●
Protocol
: type of
Protocol
sent by the chosen sensor. The protocol may be
accompanied by a synchronized
PPS
(for
UTC
) used to record incoming data. The 4
PPS options are: rising or falling edge, before or after the data .
Timeout
(for
Pressure
) of
the PPS below which it does not operate can also be recorded. see Appendix H.
●
Serial
: (only for GPS) if the chosen link is
Serial
, the link parameters are as follows:
> Parity
: None, Odd, Even
> Stop bits
: 1.0 or 2.0
> Standard
: RS422/485 or RS232
> Baudrate
: selected from a predefined list ranging from 1,200 to 115,200 bauds
●
Ethernet
: if the chosen link is
Ethernet
, the link parameters are as follows:
>
Transport layer
: may be TCP Server, TCP Client or UDP Broadcast (only TCP
Client for the GPS case).
> IP
: the IP address of the target (only for a transport layer
TCP Client
)
> Port
: the number of the port
●
Lever arms
(only for
GPS
): the lever arms represent the distance along the vessel’s three
reference axes between the position of the sensor and the position of the CRP.
●
Forced Mode
(only for
GPS
): the INS inside GAPS takes all GPS positions that come in
input whatever their quality might be. If the GAPS is turned off in forced mode, it will
restart in forced mode.
