as well as in the FDL-978 Series. The installation configuration data in the PM (if present) is
copied to the FDL-978 Series at power-up. Both the PM and the FDL-978-RX/XVR configuration
data are stored during the installation configuration process. The PM module is optional but
simplifies the process to replace a serviced FDL-978 Series. Section 2.8 details installation of
the PM.
The TC978 Controller (if used in the installation) also contains a back-up copy of the installation
configuration data. If the PM is not installed the TC978 Controller will automatically re-configure
the FDL-978-XVR if it is replaced in the installation. However, if the TC978 Controller is
replaced in an installation without the PM, the FDL-978-XVR MUST be re-configured.
The PM connections are on the following pins:
PIN SIGNAL
J1-14 Vpm
J1-30 GND
J1-43 CLK_PM
J1-44 DATA_PM
The PM has no lightning protection. The wire length between the PM and Power
and I/O connector should be less than 4 in.
