7.8 i-BUS Setup
7.7 i-BUS2 Setup
This function is used to set up the i-BUS expansion module.
The i-BUS function is mainly used for servo expansion. If a cable is too short or the number of servos exceeds the
outputs for the receiver, the i-BUS module provides a convenient option for expansion. When using the i-BUS
receiver, make sure that it is powered separately to ensure that servos have sufficient power.
This function is used to set up the i-BUS2 devices, such as FS-iBH07 Hub or servos with i-BUS2 protocol.
• Firstly at the transmitter side, set the receiver interface connected to the hub to i-BUS2 via [RX interface
protocol] function.
• Currently, it is only available for FS-iBH07 HUB.

Setup:
1. Turn on the transmitter, enter [SYSTEM], touch [Channel Number Definition], and
select the number of channels to be set (optional 2、4、6、8、10、12、18 channels,
the system defaults to 8 channels).
2. Go to [RX SET] and bind the transmitter and receiver (see user manual for more
information).
3. Touch [RX Interface Protocol] and select “i-BUS” (if “Sensor” is selected, the i-BUS
port on the receiver cannot be used for channel expansion).
4. Connect the FS-CEV04 to the FGr8B/FGr4B receivers "i-BUS out" port.
5. Touch "i-BUS Setup" and select the channel to be assigned, (touch "channel X",
the system display a "Assigning channel X, Press the corresponding key on the serial
BUS receiver to assign") Use the appropriate tool to press the K1, K2, K3 or K4 button
on the FS-CEV04 to assign the selected channel to C1, C2, C3 or C4. If successful, the
transmitter will display: "Channel assigned to interface X / Servo X".
6. Connect the servo to the corresponding port and check if it is working as expected.
7. Repeat the above steps as needed.

FS-iBH07 Extender
When the transmitter detects the i-BUS2 HUB device, the i-BUS2 HUB device can be set
as a PWM converter or reset it back to the i-BUS2 HUB device via this function.
Setup:
1. Click [i-BUS2 Setup] to enter the setting menu.
2. Tap [i-BH07 Extender NPA], then click [Set to PWM converter]. After click [OK] in the
pop-up window, tap [PWM Coverter NPA].
3. Tap [Set to i-BUS2 Extender] to set it back to HUB. Click a channel to set as the output
channel of the converter.
4. Tap to return, a propmt pop-up window comes along with it "Whether to set the
frequency of PWM converter synchronous", then click [YES] or [NO] to exit. If you select
YES, it will be synchronous, otherwise,it's in the contrary.
• The voltage returned from the extender can be displayed in real time in the [Sensor]
menu.
• When a servo is connected to the interface set to i-BUS2 protocol, it will display the
servo type and the interface in [i-BUS2 Setup] menu.
