How to use

Attach the NM9MF adapter inline to a straight-through DB9 cable by connecting the male and female ends as needed to form a null modem connection. Once connected, link each end of the cable to the serial ports on the devices to enable direct RS232 communication.

For reliable operation, use the adapter with good-condition DB9 cables and confirm matching serial settings on both devices. Keep connections dry and avoid excessive bending or strain on the cable and adapter.
