General Characteristics

RS-232 connector

This male DB-9 connector is an RS-232 serial port that can be used for controlling the signal generator remotely. It is functionally equivalent to the GPIB connector. The following table shows the description of the pinouts. The pin configuration is shown below.

Pin number			Signal description		Signal name
1			No connection
2			Receive data		RECV
3			Transmit data		XMIT
4			+5 V
5			Ground, 0 V
6			No connection
7			Request to send		RTS
8			Clear to send		CTS
9			No connection
