[转帖]关于Celestron, Meade手柄和PC连接的串口线制作http://www.bisque.com/help/theskyV6/Telescope/Telescope_Interface_Cables.htm

看来Meade的Autustar和Celestron的Nexstar都采用RJ22的小接口，只是用的引脚不一样。

Signal Pin	To Pin
1	Data Carrier Detect
2	Receive Data (Rx Data)
3	Transmit Data (Tx Data)
4	Data Terminal Ready
5	Signal Ground
6	Data Set Ready
7	Request to Send
8	Clear to Send
9	Ring Indicator

Note: On the ActiveSync cables (mobile devices), pins 2 and 3 are swapped so that the mobile device (which is connected to the RS232 serial port) can send/receive data the COM port.
