Notes:
*1.This rating applies to all parts of the module and should not be exceeded.
*2.The operating temperature only guarantees operation of the circuit. The contrast, response speed and the other
specification related to electro-optical display quality is determined at the room temperature, TOP=25 ℃ Ambient
temperature when the backlight is lit (reference value)
*3.Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional
operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure
to extreme conditions may affect device reliability.

9 Assemble Precaution
安装注意事项
1. Customer front panel opening and thickness for TOPWAY
display module should be fit for its assembling and sealing.
The suggested assemble gap(A) should be about
0.3~0.5mm on each side.
The suggested front panel thickness(B) should be
about 1.5~4.0mm.
客户面板开窗及厚度应适合 TOPWAY 显示模块的安装及密
封 .
建议每边安装间隙 (A) 约为 0.3 ~0.5mm.
建议面板厚度 (B) 约为 1.5~4.0mm.
2. A silicon sealing ring ships with TOPWAY display module.
It should be in place before assembling to the front panel.
TOPWAY 显示模块上的硅胶密封圈在安装时确保嵌入到
位 .
3. It should fix the TOPWAY display module into the front
panel with two steps.
Pre-fixing: Slightly tighten the screws on beam clamp in
sequence as picture on the right side.
Final-fixing: Tighten the fixing screws on beam clamp in
sequence as well with twist torque about 6~8kg.cm
(*1) . and put the beam clamp straight.
Note:
*1. Over tightening might damage the shell and cause bad sealing result.
应分两步将 TOPWAY 显示模块固定在面板上 .
预紧 : 将卡扣螺钉按右图所示顺序稍加预紧 .
紧定 : 再次按顺序用 6~8kg.cm 扭力拧紧卡扣螺钉 (* 1),
并注意卡扣置正无歪斜 .
注 :
*1. 过度拧紧可能会损坏外壳和影响密封效果 .
4. It is strongly suggested to check the seal balancing of the
four-side of the TOPWAY display module.
The suggested after assemble sealed gap(C) should be
about 1.0~1.5mm.
需注意检查 TOPWAY 显示模块四周在安装后保证平衡密封 .
建议组装后的密封间隙 (C) 约为 1.0 ~1.5 mm.
5. Others:
Never hot plug the device! Power off the device before connect or disconnect the display module.
Don't forget to remove the cover protective film for normal operation.
其它 :
视频线禁止带电插拔! 在连接或断开显示模块之前先关闭设备电源 .
使用前请揭去保护膜 .

配置类
说明
功能
<config>
关系定义
relative
- 定义 VP 与 MB 的对应关系
- 当 VP 内容被修改 , 模块会同时拷贝相关内容到 MB
<global>
定义全局的周期性操作
Read
- 读 MB
- 可按条件操作
- 模块会参考 <config>, 同时拷贝相关值到 VP (*1)
Write
- 写 VP
- 可按条件操作
- 模块会参考 <config>, 同时拷贝相关值到 MB(*1)
