SG 2000 Installation and Operation Manual

If you are using a single DS-SG2-DRT-2X/A transmitter, it must be installed in the optical

transmitter A position. A JXP-5A (5 dB) pad must be installed in the pad facility at the input of both

the A and B transmitter locations. With this transmitter, the SG2 is configured with the return path

module/split (SG2-RPM/S). Return signals from two of the four node ports are fed to one RF input

of the transmitter while the remaining two return signals are fed to the second RF input as illustrated

in Figure 5-11:

Using a DS-SG2-DRT-2X/A transmitter in conjunction with an optional second transmitter (B)

provides return redundancy as illustrated in Figure 5-12. Installing a redundant B transmitter requires

you to remove the JXPs that are installed before the input to the transmitter and replace it with a

special adapter in order to route the signals properly.
