Connecting the BSR
Connecting BSR to the BSDU
The BSR's 15-pin D-type port is connected to one of the eight BSDU's rear panel 15-pin D-type
ports (labeled Radio 8-1).
The BSR-to-BSDU cable setup is as follows:
Cable: straight-through 10/100 Base-T Ethernet 4 Pair Cat-5e outdoor type – 22 AWG (100
meters)
Connectors:
o BSR side: 15-pin D-type male (only 8 pins are used)
o BSDU side: 15-pin D-type male (only 8 pins are used)
Connector pinouts:

Notes:
A CAT-5e cable connects to the 15-pin D-type port, therefore, only eight pins are used (i.e.
pins 9 through 15 are not used).
The wire color-coding described in the table (and shown in the figure below) is AS.MAX's
standard for wire color-coding. However, if you implement your company's wire color-coding
scheme, ensure wires are paired and twisted according to pin functions (e.g. Rx+ with Rx-).
When the BSR is connected to an SDA, pins 7 and 8 are not used (i.e. no synchronization).
To connect the BSR to the BSDU:
1. Connect the 15-pin D-type male connector, at one end of the CAT-5e cable, to the BSR's
15-pin D-type port labeled DATA&PWR&SYNC.
2. Connect the 15-pin D-type male connector, at the other end of the CAT-5e cable, to one of
the eight BSDU's 15-pin D-type ports labeled BSR, located at the rear of the BSDU.
