3.2.4 Remote LEDs and Recovery Switch
The Canopy 150/300 PIDU provides a facility to connect remote LEDs and Recovery switch
allowing the 150/300 PIDU to be mounted inside an enclosure. At the left hand end of the
150/300 PIDU under the ODU connection cover can be found a PCB header and three
jumpers. Jumpers J906 and J907 should be removed and connection to the remote LEDs and
Recovery switch made to J908 as shown in Figure 10 .
