a. Connect the RS-232 port (RJ-45 connector) on the BRI NSU to a
serial port on the PC.
b. Set up the communications program on COM port 1 or 2 with the
following parameters:
- Baud Rate: 9600
- Data Bits: 8
- Parity: None
- Stop Bits: 1
- Flow Control: XON/XOFF
- Character Set: ASCII
5. Connect power to the BRI NSU.
6. On the PC, program the BRI NSU using a VT100 emulator (see TB

Analog Services Unit
This procedure applies to the ASU, the Universal ASU, and the ASU II
(compatible only with Release 7.0 software). You can connect up to four
Analog Services Units to the controller (two for the MX and 100-user
controllers). Ensure that there is a free CIM port on the controller.
ASU II mounting instructions:
• For rack mounting (rear or front facing), do not install the feet
• For wall mounting, install only the two bottom feet.
1. Mount the ASU. Refer to page 141 for ASU II line card installation
instructions.
2. Connect a Crossover Category 5 cable with RJ-45 connector to the
CIM port on the ASU and a free CIM port on the controller (see
Table 55 on page 269).
Tip: Even though the TB is written for the SX-2000 system, the parameters
described are also applicable to the 3300 BRI NSU.
