ROLINE Serial Link Cable 11.01.9018 connects two PCs through their serial interfaces, with the cable acting as a null modem. It is intended for serial links that need this crossed signal arrangement.
The cable is 1.8 m long and has a 9-pin D-Sub female socket at each end. Both connectors have hand-locking screws, and the grey cable is screened to help limit electromagnetic interference.
The moulded plastic connector housings help reduce strain on the cable at the ends. The pin mapping differs between the two sockets to support its null-modem function.
