Top 3 Customer Questions & Concerns �
� Is this a "Null Modem" cable? Unless specifically labeled otherwise, this is a straight-through extension cable. If your application requires a Null Modem (crossover) connection, you would typically use this in conjunction with a Null Modem adapter.
Can I use this for VGA video? No. While the DB9 connector looks similar to a VGA port, standard VGA uses a High-Density 15-pin (HDS15) connector. This cable is strictly for 9-pin serial data.
� Will this work with my modern USB-only laptop? Most modern laptops do not have native DB9 ports. To use this cable, you will need a USB to RS-232 Serial Adapter to bridge the connection between your USB port and this DB9 link.
