Used DMP 462N - pulled from working installation during upgrade. Not tested. Board only.

The 462N Network Interface Card allows the XR500 Series and XR2500F Command Processor™ Panels to communicate
alarm, trouble, and system reports to the central station over existing computer data networks. The 462N allows you
to configure the baud rate settings to match the network interface, and provides Transmit and Receive LEDs to verify
network communication.

The 462N card also provides a supervised, power limited 4-wire LX-Bus™ to expand connection capacity of the panel
LX-Bus so you may attach any combination of LX-Bus devices.
