[求助]雅培C16000数据传输问题

国内刚刚安装了一台c16000，链接lis（瑞美），不知怎么的就是没有数据信号的传输。

c16000所用的数据传输线盒串口线和以前其他的设备也不一样，现在为25母转9母，其线序为：

9针母头 25针母头

2—— 2

3—— 3

4—— 6

5—— 7

6—— 20

7—— 5

8—— 4

不知道是哪里的问题，关于比特率等通讯参数设置都按照要求，希望有经验的同行给予解答

1600的串口线是非标的。

这是主机25针的接口，自己查找对应计算机9针串口就是。

Pin 1: Chassis Ground
Pin 2: Selectable at installation as either Data to Host or Data to System  TXD
Pin 3: Selectable at installation as either Data to Host or Data to System RXD
Pin 4: Selectable at installation as either Request to Send (RTS output) or Open
Pin 5: Selectable at installation as either Clear to Send (CTS input) or Loop through to Pin 20 or High or Open
Pin 6: Selectable at installation as either Data Carrier Detect (DCD input) or Loop through to Pin 8 or High or Open
Pin 7: Signal Ground
Pin 8: Selectable at installation as either Data Carrier Detect (DCD input) or Loop through to Pin 6 or High or Open
Pin 20: Selectable at installation as either Clear to Send (CTS input) or Loop through to Pin 5 or High or Open

 

有些可连可不连。连接好后用超级终端测试一下就知道了。

9针串口	MF 25针
2	2
3	3
5	7
4短接6	4短接5
7短接8	6短接20

 

可以试试这种连接
