Learning About the 9181 Base Radio Unit
The 9181 Base Radio Unit (BRU) links the Model 200 Controller or another
Intermec network controller to the Intermec 900 MHz RF data collection
network. It broadcasts information from the controller to the Intermec RF
devices and receives RF signals from the devices, passing the information back
to the controller.
Note: The only physical connection to the BRU, other than the power cord, is to a
serial port on the controller. The antenna attaches to a connector on the front panel,
either directly or through a coax cable.
Understanding the BRU Components
This figure shows the components for the BRU. The communications port
connector, status LEDs, antenna connector, and power cord are all on the front
panel.

Understanding the BRU Status LEDs
The front panel of the base radio unit contains three LEDs that continuously
display the status of the unit. During power up and self tests, all LEDs are on
and then they turn off. If all tests pass, the LEDs will show the status described
in this table.
LED Description
Power Indicates the BRU is receiving power.
Radio Rx/Tx Lights when BRU is receiving or transmitting a packet through
the radio.
RFNC Rx/Tx Lights when the BRU is receiving or transmitting a packet of
information with the controller.
Note: When the 9181 is connected to a controller, the controller sends out a packet
every second. This causes the Radio Rx/Tx and the RFNC Rx/Tx LEDs to blink once a
second.
Installing the BRU
To install the BRU, make sure that you use cables that are appropriate for the
distance between the BRU and the controller. Then, use one of these
procedures.
Mounting to Drywall Surfaces
If mounting the unit to drywall (sheetrock), make sure it is mounted on a
ceiling joist. Plastic anchors in drywall will not safely support the BRU.
Mounting to Wood Surfaces
If mounting the unit to wood, the minimum thickness must be 0.5 inch (12.7
mm). Use 5/16-inch sheetmetal or wood screws.
9181 Base Radio Unit

Mounting to Metal Surfaces
If mounting the unit to a metal surface, the minimum unreinforced thickness
must be 14 gauge (steel).
To install the BRU
1. Locate the BRU within 4 feet (1.22 m) of a power outlet.
2. Bolt the BRU to the rafters so the antenna points down. The front panel
LEDs should be visible from the ground.
3. You may want to review the section “Terminating the Cable at the BRU”
carefully before you continue.
Route the cable between the BRU and the controller and secure with plastic
tie wraps or cable clamps. At the end of the cable near the BRU, create a 7-
inch drip loop to prevent water from leaking into the connector. Leave a
similar loop in the power cord.
4. Attach the antenna to the BRU so it points down. Make sure it is at the
lowest point of the ceiling and reaches below all beams, pipes, and ducts.

Connecting the BRU to the Model 200 Controller
To connect the BRU and the Model 200 Controller, you need to know if you
have a 2-port or 4-port RF controller card in the controller. You will also need:
• Intermec cable kit (Intermec P/N 055003) or equivalent. Each kit contains
two sets of connectors and pins: one for the controller and one for the BRU.
• Belden 89688 cable (Intermec P/N 583326) or equivalent. The BRU and the
controller may be separated by as much as 2,000 feet (650 meters) with a
data rate of 64 Kbps.
To connect the BRU to the Model 200 Controller
1. Refer to “Terminating the Cable at the BRU” and “Terminating the Cable at
the Controller End” later in this chapter for important information on
terminating the cable before you connect the BRU and controller.
2. Connect the 9-socket end of the cable to the controller.
• If you have a 2-port RF controller card, connect one end of the Belden
cable to one of the ports on the card.
• If you have a 4-port card, Intermec provides you with a 4-port interface
cable. Insert the controller end of the interface cable into the port on the
RF controller card. Connect one end of the Belden cable to one of the
downline connectors (DNLN 1, DNLN 2, DNLN 3, or DNLN 4).
3. Connect the other end of the cable to the BRU.
Connecting the BRU to the 9180 Controller
To connect the BRU and the 9180 Network Controller, you need:
• Intermec cable kit (Intermec P/N 055003) or equivalent. Each kit contains
two sets of connectors and pins: one for the controller and one for the BRU.
• Belden 89688 cable (Intermec P/N 583326) or equivalent. The BRU and the
controller may be separated by as much as 2,000 feet (650 meters) with a
data rate of 64 Kbps.

2. Connect the 9-socket end of the cable to one of the downline connectors
(DNLN 1 or DNLN 2) on the controller. Refer to the table on the next page
for DNLN port pin assignments.
3. Connect the other end of the cable to the BRU. Refer to the table on the next
page for BRU pin assignments.

Terminating the Cable at the BRU
The conductor and cable shield for the BRU must be terminated properly. Do
not terminate the cable with any other connector than the ones that Intermec
recommends. Placing a DB-9 or any other connector at the BRU end of the cable
and then running a short cable to the BRU connector is not acceptable and will
result in poor performance.
Note: If you are attaching the connector to the cable before running the cable along the
ceiling, make sure the cable will not have to pass through any small holes or other
obstructions that will not let the connector through.
You may want to test or Ohm out the cable for shorts before connecting it to
either the BRU or the controller.
Connectors That Require a Banding Tool
Follow the instructions that come with the cable carefully. The bands that
secure the cable shield to the BRU connector backshell is a standard shell (0.25
inch) and can be tightened with any automotive CV joint boot banding tool.
Note: Do not overtighten the band or it will cut through both the shield and the
internal wires.
Once the shield band is installed, make sure you heat the waterproof heat
shrink in place to protect the back of the connector.
Clamp-Type Connectors
Note: If you are using the clamp-type BRU connector, assemble the BRU connector kit
onto the end of the cable. Make sure the cable shield is properly terminated in the
connector backshell.

Terminating the Cable at the Controller End
Once the BRU is mounted and the cable is routed and secured to the controller,
size up the cable and provide plenty of extra cable length before you cut the
cable.
Cut the cable and terminate it with the 9-pin D shell connector from the kit.
Note: It is very important that you connect the cable shield to the backshell of the
connector.
Troubleshooting the BRU
During power up and the self tests, all LEDs are on. If any of the self tests fail,
the LEDs will blink. The LED blink patterns are listed in this table.
Fault Radio Rx/Tx LED RFNC Rx/Tx LED
ROM Test rapid blinking rapid blinking
RAM Test rapid blinking off
CPU Test off rapid blinking
Note: Do not confuse the rapid blinking in the self tests with the blinking (every
second) that occurs when the controller sends out status packets. To verify which
blinking is occurring, disconnect the BRU from the controller.
