【经验】如何配置USB桥接器件CH9102F固件VID/PID/String参数

时间： 2023-04-01 来源：世强

技术问答

沁恒微电子在连接与控制通信领域，推出USB高速/全速转串口系列芯片，可实现USB转1/2/4/8路串口，支持串口I/O独立供电，支持VCP/HID/CDC/AOA转串口，VCP串口支持硬件流控和高波特率大数据连续传输，部分型号支持VID/PID/String等内容配置，本文将以USB桥接器件 CH9102F为例，介绍通过ch34xSerCfg.exe软件进行VID/PID/String设置。如下图1：

图1.ch9102FVID/PID/String配置图

1、在电脑usb端口连接好CH9102F设备，启动CH34xSerCfg.exe软件，如图1在左边目录选择相应设备，进入软件配置界面。

2、进行VID/PID/String设置，然后点击写入配置。

通过上述操作CH9102F配置VID/PID/String参数后就烧录固件应用即可。
