3.2.2 Servo data (RX SERVO)

To switch to the servo data display, press the ENTER button repeatedly until RX SERVO appears on the

screen.

Channel select (OUTPUT CH): here you select the desired channel; the remainder of the settings in this

display only affect the channel which you select at this point.

Servo reverse (REVERSE): sests the direction of rotation of the connected servo

Normal: REVERSE OFF

Reverse: REVERSE ON

Servo centre (CENTER): The “CENTRE” line displays the current pulse width in μs of the control channel

selected in the “OUTPUT CH” line. The displayed value varies according to the current position of the

transmitter control which affects this control channel, and also its trim position. A pulse width of 1500 μs

corresponds to the standard centre position, and therefore the usual servo centre setting.

To change this value, select the “CENTRE” line and touch the INC + DEC buttons simultanously. Move the

corresponding transmitter control to the desired position, and touch the INC + DEC buttons again to store the

current transmitter control position. This position is now stored as the new neutral position.

Trim position (TRIM): The purpose of the “TRIM” line is to provide ﬁ ne adjustment of the neutral position of

a servo connected to the control channel selected in the “OUTPUT CH” line. Adjustments are made in 1 μs

increments using the INC or DEC buttons. The value in the “CENTRE” line can be adjusted over the range

+/- 120 μs around the TRIM value set here.
