NOTE:
A P1 FLN license must be installed in order to use Wireless FLN.
NOTE:
The PXC Compact on P1 is not supported on the Wireless FLN.
The following additional hardware is required to implement the Wireless P1 FLN with
the PXC Compact Series:
● Field Level Network Transceiver (FLNX)
● Field Panel Transceiver (FPX)
See the section Minimum Firmware Revision Required for information on the firmware
revision required to implement Wireless P1 FLN.
PXC Compact on P1
The PXC-16 and the PXC-24 may be configured to reside on the P1 Field Level
Network (FLN). When configured for the FLN, the PXC Compact functions as a
programmable FLN device, which accepts custom applications.
Virtual AEM
Without additional hardware, the Virtual AEM connects an RS-485 APOGEE
Automation Level Network (ALN) or individual RS-485 field panels to a P2 Ethernet
network.
● An additional license is required.
USB Host Port
The USB host port supports a USB printer and connection to a modem through a USB-
to-RS-232 adapter. A USB hub may be used to support both a printer and modem on
the USB host port.
● On a BACnet/IP ALN, the USB Host port provides support for service modems and
line printers.
● On an Ethernet TCP/IP or RS-485 ALN, the USB Host port provides support for
dial-up or service modems and line printers.
TX-I/O Island Bus
The PXC-36 offers the flexibility of expanding the total point count through a self-
forming island bus. With the addition of TX-I/O modules and a TX-I/O Power Supply,
up to 32 points (or four TX-I/O modules) can be supported.
An additional license may be required to enable the Island Bus.
