4.22 J24 数据串口 2 Data Serial Port 2
【J24】内置串口 2(单排 2.0mm-方孔为 1脚),默认为 TTL 电平且可配置为 RS-232 或RS-485 电
平(焊接 U62 则为 RS-232 电平、焊接 U67 则为 RS-485 电平); 对应的软件编程设备节点为 ttyS2。
[J24] Built-in Serial Port 2 (SIP 2.0mm-Square pad is pin 1). The output level is TTL by default and it could be
setup to RS-232 if required (RS-232 if U62 mounted, RS-485 if U67 monted). The related software device
node name is ttyS2.

注意:如需将调试串口作为数据串口使用,则请联系供应商获取定制版本软件;在上电的前 5秒
此串口会输出启动信息(上位机或下位机需要处理数据容错)。Note: If you need to use the debugging
serial port as a data serial port, please contact the supplier to obtain the customized software; this serial
port will output the startup information in the first 5 seconds of power on (the upper or lower machine
should handle this kind of data fault tolerance).

【J26】LVDS 驱屏跳线接口(双排 2.0mm-方孔为 1脚)。1和2脚跳线帽短接则 J15 的VLCD 为
12V,3和4脚跳线帽短接则 J15 的VLCD 为5V,5和6脚跳线帽短接则 J15 的VLCD 为3.3V。请根据
实际使用的液晶屏的逻辑电压调整跳线帽位置,注意不要跳错位置否则会造成液晶屏和主板电路的
损坏。
[J26] LVDS Voltage Header (DIP 2.0mm-Square pad is pin 1). If pin 1 and 2 are jumper shorted, the VLCD
of J15 is 12V. If pin 3 and 4 are jumper shorted, the VLCD of J15 is 5V. If pin 5 and 6 are jumper shorted, the
VLCD of J15 is 3.3V. Please adjust the jumper position according to the actual logic voltage of the LCD screen.
