Motorola SG2-DRT-3X 用户手册

The SG2-DRT-3X transmitter can operate with three data streams. If you install the 
SG2-DRT-3X in an SG2440 that will remain a combined (1X) or split (2X) return, an additional 
cable is provided to properly load the transmitter. 

To properly cable the SG2-DRT-3X for a combined or split return: 

1 

Verify that the SG2440 return configuration plug-in board is either a redundant (1X) or a 
split (2X) model. 

2 

Insert the provided cable from the redundant transmitter’s D subconnector into RF 

INPUT 

A 

or 

INPUT 

B on the SG2-DRT-3X as illustrated in Figure 8. 

 

3 

Change the 15 dB JXP pad at the XMTR A location to a 5 dB JXP. 

You can equip the SG2000 with a combined or a split-return path module and still be compatible 
with the SG2-DRT-3X. 

On SG2000 nodes equipped with an SG2-RPM/C, you can select any two RF ports for 
segmentation. The two remaining ports will automatically be combined and put on the 
D subconnector beneath the double-wide transmitter. 

On SG2000 nodes equipped with an SG2-RPM/S only, you can segment RF ports 1 and 3. Ports 
2 and 4 are combined and are automatically put on the D subconnector. 

The segmented inputs occupy the ICS plug-in location. If equipped, ICS functionality will be lost 
on these two ports.
