10.4. Futaba S.Bus2
The GPS-Logger 2
can also
be used with the Robbe / Futaba FASSTest telemetry as
an
S.BUS2 sensor
.
The GPS-Logger 2 is in this case connected like any other sensor to the
S.BUS2 slot of the receiver.
Currently the GPS-Logger 2 is not yet registered in the transmitters
, so it
uses already
existing sensor protocols. We tested the integration with the T14SG firmware v1.4
,
and the
T18MZ Firmware v2.3.1 with the receivers and R7008SB R7003SB
.
Older firmware versions
support the integration but possibly incomplete.
With S.BUS2 Servo data sensor values can be connected to the same data line. But since the servo
data is far more important than the sensor values we strongly recommend that you make a strict
separation. All servos go to the S.BUS1 connection of the receiver, all the sensors on the S.BUS2.
Thus, in the event of an error, a sensor can never interfere with the data for the servos. If
nevertheless the
GPS-Logger
2 is to be operated together with the servos on S.BUS2, is absolutely
mandatory that a connection cable No. 9110 is used between
GPS-Logger
2 and S.BUS2! Thus the
sensor is decoupled from the bus so far that any influence on the servo data is impossible.
10.4.1. Registration on the Transmitter
To use the GPS-Logger 2 with the S.BUS2, it must like all S.BUS2 sensors be first
registered on the transmitter. Us
e the “Llink" connector on the GPS-Logger 2 on a V cable
with the "SI / F" connector on the transmitter and a receiver battery connected for the power
supply . The GPS-Logger 2 behaves like a Robbe / Futaba sensor and is thus closely
integrated into the system. Please also refer to the transmitter instructions.
However, the
GPS-Logger
2 currently uses three Robbe / Futaba sensor values to represent all
measured values. Some values cannot be mapped to the correct unit. Here one must remember the
assignment with theT14SG, in the T18MZ you can rename the sensors and thus the assignment is
easier to understand.
The example of the T18MZ here follows the steps of the application
:
If the
GPS-Logger
2 is connected to
the transmitter and is supplied with
power, it is invoked in the sensor
menu item "Login". In this way the
sensor is registered in the
transmitter and assigned free slots.
The sensor and transmitter save
this assignment.
To be able to represent all values the menu item "Login" on the transmitter must necessarily be
called three times. The message "OK" will appear four times, at the fifth time the message is "sensor
already exists".
