*1: The cables connected to the analog input terminals should be kept separate from other
power cables and cables which generate noise.
*2: If the text panel is connected to a current signal, the terminals V3+ and I3+ must be
short-circuited.
*3: If the ripple in the input voltage results in the noise interference with the wiring, please
connect the text panel to the capacitor having a capacitance in the range of 0.1 μF to 0.47 μF
with a working voltage of 25 V.
*4: Please connect the ground terminal on a power supply module and the analog input terminal
FE to the system ground, and then ground the system ground or connect the system ground
to a distribution box.

Terminal resistor
Note: 1. The terminal resistor should be connected to the master station and the last slave
station. The resistance of the terminal resistor should be 120.
2. To ensure communication quality, it is suggested that users should use double shielded
twisted pair cables (20AWG) for wiring.
 Communication Connection
TP04P may connect to a PC by using USB adaptor cable.
Please use an AM/BM USB adaptor cable.
