Frequently asked questions
Does a gender changer alter the pin-to-pin wiring?
A standard gender changer is a straight-through adapter, so each pin connects to the same pin number on the other side. Check the wiring if you need a crossover or null-modem connection.
Can it be used for RS-232 serial communication?
Yes, DB9 is the common connector for RS-232 serial ports. Confirm the signal mapping of your cable before connecting it to a device, because some equipment uses a different pinout.
