Null Modem Cable is used to connect through a serial connection to the routerboard console using a utility like minicom or hyperterminal. These cables are not widely available in retail stores so you will most probably have to hack a standard serial cable into a null one by opening up both connectors and rearranging the cable connections to one of them.
Tips:
- The best way to do it is by soldering the wires to the connector. So most of the tips apply to this case.
- All serial connectors have their pins numbered in both sides. This is really useful when you rearrange the wires, because thinking of the connector schematic can be really confusing.
- Careful with the ground wire! Don't forget to put the insulating cover!
- Don't heat up to much the connector pins because you may damage the connector.
