Is this a "Null Modem" adapter?
No. This is a Straight-Through gender changer. It does not cross the TX/RX lines. If your devices require a Null Modem connection, you would need a specific Null Modem adapter.
Will this work for VGA?
No. While it looks similar, VGA uses 15 pins (HDS15). This is a 9-pin serial adapter.
Can I leave this plugged in permanently?
Yes. The metal shell and screw-locking mechanism make it suitable for permanent installation in industrial environments.
