FAQs
I am using the Alarm Lock MX1130 USB to RS-232 cable or the AL-PCI2-U kit (includes both the MX1130 cable and an AL-PCI2 serial COM port (DB-9 plug) to banana plug cable). Which of the three drivers available on the Napco Technical Library website (tech.napcosecurity.com) should I install for use with the USB adapters?
Any one of the three drivers will work with your Alarm Lock AL-PCI2 cable and MX1130 cable. However, to ensure you have the latest version driver, we recommend you search the Napco Technical Library website (tech.napcosecurity.com) with the words "USB Drivers for the Alarm Lock USB to RS-232 Serial COM Port Cable" and the web page that appears will contain the latest version.
