Do any RC Servo boards have a pull-up resistor on the signal wire?

Hello Phidgets Forums,

I have a Feetech FT8346M RC servo motor (360° position control).

https://www.feetechrc.com/74v-40-kgcm-d ... -gear.html

On the last page of the datasheet is the Interface Definition, where it shows the below schematic:

It shows a 10 kΩ pull-up resistor to 3.3 - 5 Vdc on the signal wire.

In either the RCC1000_0 or the RCC0004_0 RC servo control boards, is there a pull-up resistor on the signal wire? If yes, is its value 10 kΩ, and is the voltage in 3.3 - 5 Vdc?
