Silex technology SX-560 manual DB-9 RS-232 Signal Type, Rts, Cts

DB-9	RS-232 Signal	Type
7	RTS	Output (not supported on Serial Port 3)
8	CTS	Input (not supported on Serial Port 3)
9	NC

Serial Port 1 can also be accessed using logic signals via a 10-pin header located at JP6. If you want to use this header, you must place a jumper on the 2-pin header at JP10 to disable the RS-232 transceiver. The pinouts are as follows:

Table 6 Logical Serial Port 1 Signal Descriptions

Pin	Signal	Input/Output	Pin	Signal	Input/Output
1	DCD	Input	2	DSR	Input
		Enabled via JP9 header			Enabled via JP9 header
3	RXD	Input	4	RTS	Output
5	TXD	Output	6	CTS	Input
7	DTR	Output	8	No
		Enabled via JP9 header		Connect
9	GND		10	3.3V

All signals are 0 to 3.3 V logic signals.

The console port (Serial Port 3) can be also be accessed via the 26-pin I/O header pin headers (pin 19 for TxD and pin 22 for RxD). The console port is normally set to use the DB-9 connector; to use the 26-pin I/O header, remove the jumper on the header at JP11 so that two sources are not driving the RXD2 signal.

Note that Serial Port 3 is dedicated for use as a console port for configuring the SX-560. Serial port 3 is always set for operation at 115.2Kbps, 8 bit character size, no parity, and no flow control.

Serial Port 2 is set by default for console operation at 115.2Kbps, 8-bit characters, no parity, and no flow control. This port can be set as a second I/O port using the SET PORT S2 CONSOLE DISABLE console command.

RS-232 Cable

The supplied DB-9 female-to-female null modem cable is wired as shown below. The pinouts are compatible with a standard PC 9-pin serial connector, so this cable can be used to directly connect a PC to Serial Port 3 for use as a console terminal to configure the SX-560. It can also be used to connect many types of OEM serial devices to Serial Port 1 or Serial Port 2, provided that these devices use PC- compatible 9-pin connectors.
