A Terminator node can easily be converted into a Collector node by: 

(1)  adding a reverse optical transmitter 
(2)  disconnecting Port 1’s RG 179 cable from the launch amplifier’s reverse output SMB connector 
(3)  installing a RG 179 cable between the launch amplifier’s reverse output SMB connector and the optical 

interface board’s reverse input SMB connector 

 
A Collector node can easily be converted into a Terminator node by: 

(1)  removing the RG 179 cable that connects the launch amplifier’s reverse RF output to the optical interface 

board’s reverse input 

(2)  connecting Port 1’s RG 179 cable to the launch amplifier’s reverse output SMB connector 
(3)  removing the reverse optical transmitter
