Description
GDA-HLU1 is a USB-to-RS485 adapter(automatic data direction control) for all Gicren's standard devices, whose conversion mechanism is"USB UART(FT232RL) RS485(SP485EEN)", so it can also be used for other general purpose via pin header, such as “USBUART”, “USBRS485” and ”UARTRS485”
Features：
Taking into account security issues, there are only D+ and D- pins connected to SP485EEN. In other words, the front-end circuit and back-end circuit do not share the same ground in the printed circuit board, but it is recommended to connect them manually to avoid excessive common-mode voltage when you are sure the connection is correct.
In addition, the onboard high-quality D-Sub-9Pin-Female, SMT-PH2.0-9Pin, Header-2.54mm-Pitch-9Pin, fuse and selectable matching resistor make this adapter more flexible and reliable.

描述
GDA-HLU1是一個USB轉RS485適配器（自動數據方向控制）的所有Gicren的標準設備，其轉換機制是“USB < - > UART（FT232RL）< - > RS485（SP485EEN）”，所以它也可以是通過排針，如＆ldquo用於其他一般用途; USB < - > UART＆rdquo;，＆ldquo; USB < - > RS485＆rdquo;的和＆rdquo;的UART < - > RS485＆rdquo ;.
特徵：
考慮到安全問題，只有D +和D-引腳連接到SP485EEN。換言之，前端電路和後端電路不共享在印刷電路板相同的理由，但建議將它們手動連接，以避免過度的共模電壓時確定連接是正確的。
此外，板載高品質的D-Sub -9PIN-母頭，SMT-PH2.0-9Pin，頁眉2.54毫米間距僅9針，保險絲和可選的匹配電阻使該適配器更加靈活，可靠。
