4. The output of the transistor model is “open collector”. If Y0/Y1 is set to pulse output,
the output current must be 0.05 ~ 0.5A to ensure normal operation of the model.
a. Diode suppression: Used for lower power applications.
b. Diode + Zener suppression: Used for higher power and frequent ON/OFF
switching applications.

Note: 1. Termination resistors are suggested to both physical ends of the network with 120
Ω
resistors.
2. To ensure communication quality, apply double shielded twisted pair cable (20AWG)
for the wiring.
3. When a voltage drop occurs between the internal ground references of two systems,
connect the systems to a Signal Ground point (SG) for achieving equal potential
between the systems for stable communications.
