External hardware interlock must be configured, and GOT cannot be used as the only device for major security alarms

Backlight failure can cause touch abnormalities, and the failure logic varies among different models

Touch restrictions: GT27 prohibits touch with three or more points, and other models prohibit touch with two or more points simultaneously

Communication interruption can cause monitoring failure, and critical operations must be configured with physical switches

Network usage requires the deployment of firewalls VPN、 Antivirus protection against attacks

2. Attention (CAUTION)

Distance between communication line and power line * * ≥ 100mm**

Prohibit sharp objects from pressing the screen

Key questions and answers

Question 1: What are the mandatory security restrictions for GOT2000 touch operation? What risks will violating lead to?

answer:

GT27: Do not touch 3 or more points simultaneously

GT25/GT23/GT21: Do not touch 2 or more points simultaneously

Risk: Multi touch can cause switch misoperation, output jumping, and device misoperation, which may result in personal injury or equipment damage; When the backlight fails, the screen darkens but the touch is still available, which can easily lead to unconscious operation.

Question 2: How does GOT2000 achieve multi-level permission and security management? What are the core configuration items?

answer:

Adopting a three-level system of administrator, sub administrator, and operator:

Administrator: Fully manage accounts, password policies, and security parameters

Sub administrator: Manage low-level operators with restricted permissions

Operator: Use the screen and functions according to the level (0-15)

Core configuration:

Authentication method: account password/external serial port/USB authentication

Automatic logout: 1-60 minutes

Password validity period: 1-1000 days

Continuous error locking: 3-10 failed locks

IP filtering: Allow/block access to specified addresses

Question 3: What are the three most commonly used functions in GOT2000 maintenance diagnosis? What problems should be solved separately?

answer:

Touch panel calibration

Solution: After long-term use, there are issues with touch offset and inaccurate points, which can be restored to accuracy through four point calibration.

I/O self loop check+Ethernet Ping

Solution: Communication failure, wiring error, parameter error, quickly locate hardware/configuration faults.

Batch self check+system alarm

Solution: Crash, black screen, abnormal restart, abnormal driver, export logs for after-sales analysis.
