$7.99 In stock

Use these handy adapters to join serial devices together. These adapters "cross over" the transmit (TX), receive (RX), and control lines to allow the RS-232 ports of two serial devices to communicate with each other. You will need this if you have any DTE or DCE incompatibilities. The compact size of these adapters makes them ideal for tight spaces. These are available as Male-Female adapters, the pin configuration is as follows:

Signal	DB9 male	DB9 female	Signal
Receive	2	3	Transmit
Transmit	3	2	Receive
DTR (Data Terminal Ready)	4	6, 1	DSR (Data Set Ready), Carrier Detect
Ground	5	5	Ground
DSR (Data Set Ready), Carrier Detect	6, 1	4	DTR (Data Terminal Ready)
RTS (Request to Send)	7	8	CTS (Clear to Send)
CTS (Clear to Send)	8	7	RTS (Request to Send)
