EIA-232 PC Terminal Emulator Cables, RJ-11 6-pin to DB-9

The wiring diagram for an RJ-11 6-pin to DB-9 PC terminal emulator cable is shown in Table 1.

Table 1:  EIA-232 RJ-11 6-pin to DB-9 PC terminal emulator cable

From RJ-11	Signal	Direction	Signal	To DB-9
4	RxD		TxD	3
3	TxD		RxD	2
5	SG		SG	5
1	RTS		CTS	8
6	CTS		RTS	7
2	GND		GND	Shell

NOTES:

• This cable utilizes the RTS signal of the PC terminal emulator for hardware flow control (RTS/CTS).
• Some Unix operating systems require carrier to be present.  If this is the case, the forcedcd parameter will need to be turned on for this port at the host.
• EIA-232 cables cannot exceed 2500pF.  For information about calculating capacitance of your cable, click here.
