S.Bus terminal

Product description

The S.Bus > S.Bus terminal as well as the S.Bus > PWM terminal must be pressed onto a 3-wire cable which is connected to the battery backer DPSI 2018 leading into the wings and the fuselage. At one S.Bus cable several S.Bus terminals can be connected, so for operating of several servos e. g. inside the wing only one cable is necessary. The S.Bus terminals can be pressed onto the cable exactly in that place where the servo should be mounted. On each S.Bus > S.Bus terminal a S.Bus servo can be connected, the S.Bus > PWM terminals are designed for connecting conventional PWM servos.

Optical differentiation of terminal types

In addition to the S.bus terminal's label on the topside housing half both S.Bus terminal types can be distinguished by the colored LEDs. When connected to voltage a blue LED lights up on the S.Bus > S.Bus terminal, a red LED lights up on the S.Bus > PWM terminal.

Mounting

A 3-wire S.Bus cable must be runned e. g. inside each wing and inside the fuselage. The S.Bus cables are available in different length, they can also be shortened if necessary. In order not to produce short circuits at the cut off end of the cable, the three wires should be cutted in different lengths.

Then the S.Bus terminals can be pressed onto the cable in that places where the servos should be mounted. The connectors cut the insulator of the cable and press the inner copper strands into the gold plated contacts. Mounting onto the cable must be executed with great care. It is best to use a bench vice. It is important to lock both housing halves simultaneously and in parallel.

Observe polarity before pressing the housing halves together. Black wire = Minus (-), red wire = Plus (+), white wire = pulse. Both housing halves are labeled.

When locking both housing halves, all of the four locks must click hearable. Both housing halves can even be separated again. Therefor use a small screwdriver for carefully open the locks and remove the upper housing half step wise.

If required a mixed operation of S.Bus > S.Bus terminals and S.Bus > PWM terminals on one single S.Bus cable is possible.

Servo connection

After S.Bus terminal mounting S.Bus servos can be connected to the S.Bus > S.Bus terminal, conventional PWM servos can be connected to the S.Bus > PWM terminal.

Channel allocating/Programming

General

Before servos can be operated in the S.Bus system they have to be allocated with the correct channel numbers. S.Bus servos connected to a S.Bus > S.Bus terminal can be programmed directly. PWM servos connected to the S.Bus > PWM terminal cannot be programmed, here programming must be made on the S.Bus > PWM terminal. PWM servos are controlled by a pulse width modulated signal. The S.Bus > PWM terminal generates this signal out of the S.Bus protocol.

For channel allocating the S.Bus channel programmer SBC-1 can be used. In addition to channel allocating paramater such as direction, center position, end positions and servo speed can be programmed with USB adapter CIU-2 and PC-Link software. Alternatively channel allocating and parameter programming can be done with Futaba transmitters T18MZ, FX32 and T10J.

Please see operating manual of specific servo before programming.

Channel allocating with S.Bus channel programmer SBC-1

The S.Bus channel programmer SBC-1 must be connected directly to the S.Bus servo respectively to the S.Bus > PWM terminal. With the programmer only channel allocating is possible. For programming servo parameter USB adapter CIU-2 is suitable.

Find detailed information for channel allocating inside S.Bus channel programmer SBC-1 operating manual.

Channel allocating and programming with USB adapter CIU-2

The USB adapter CIU-2 must be connected to a PC and then plugged to the S.Bus wing cable on which the S.Bus terminals are mounted.

After starting the PC software PC-Link assign the desired address of the S.Bus servo or S.Bus > PWM terminal must be entered to the software. This address is labeled on the servo as well as on the S.Bus > PWM terminal. Due to adressing several S.Bus servos or S.Bus > PWM terminals can be contacted individually. With the software now the desired receiver channel can be transmitted to the S.Bus servo or to the S.Bus > PWM terminal. Furthermore direction, center position, end positions and servo speed can be set for the specific servo (servo matching).

Channel allocating and programming with transmitter

Both channel allocating and programming also can be done with Futaba transmitters T18MZ, FX32 and T10J. Therefor the S.Bus servo or the S.Bus > PWM terminal must be connected to the transmitter's S.Bus socket. Also an external battery for the voltage supply is necessary.
