Key issues

Question 1: What is the difference between setting the PGD controller address to 0 and a regular address? What scenarios are they used in?

answer:

Address=0: Using point-to-point protocol, not connected to pLAN network, only communicating with directly connected pCO, suitable for single machine control.

Address=1~63: Using pLAN network protocol, multiple handheld devices and controllers can be networked, suitable for centralized monitoring systems.

Question 2: What are the wiring methods and maximum distances between the PGD controller and the pCO motherboard?

answer:

Direct connection method: using RJ12 telephone line, with a maximum distance of 50 meters.

PLAN networking method: using AWG22 shielded twisted pair, maximum distance of 500 meters, branch ≤ 5 meters.

Question 3: The PGD handheld device itself does not have buttons. How to set parameters, modify addresses, and adjust contrast?

answer:

Address/Network Configuration: Use the built-in combination key ←↑↵ on the handheld device to enter.

Contrast adjustment: Long press+Prg with ←/↑ adjustment.

Daily operation: An 8-key membrane keyboard can be connected externally to achieve complete operation.
