Please help me solve this

I have a 24V power supply, a transmitter, and a 250-ohm resistor. How should I connect them so that I can use the 375 handheld controller to read the transmitter’s parameters? It would be ideal to draw a diagram! Thank you so much! ! !
The positive terminal of the 24V power supply is connected to a 250-ohm resistor, which is then connected to the positive terminal of the transmitter; the negative terminal of the 24V power supply is directly connected to the transmitter’s terminal. Once the transmitter has started up, simply hang the hand controller on the terminal designated for it on the transmitter
Haha, what a coincidence – this is a rough sketch I drew for a colleague this morning
First, you need to check whether the transmitter supports Hart – don’t get too excited yet!

Connect one end of the resistor to the positive terminal of the power supply, the other end of the resistor to the positive terminal of the transmitter, and the negative terminal of the power supply directly to the negative terminal of the transmitter. 375 directly on the positive and negative electrodes.
Power supply, resistor, and transmitter connected in series; 475 is connected to the transmitter’s terminal
Connect the positive terminal of the power supply to the resistor, and then to the positive terminal of the transmitter; the negative terminal of the transmitter should be connected to the negative terminal of the power supply. In other words, simply connect the power supply, the resistor, and the transmitter in series. The two clamps of the handheld device can be used to connect across the resistor
