10.1. Overview
The IDR device is an optional WipLL device that combines the functionality of the
SPR and SDA devices. The IDR has a built-in antenna that provides an interface for
transmission with the base station. In addition, the IDR provides an interface for
10Base-T Ethernet with the subscriber's network. However, unlike the SDA, a
separate power supply unit (power adapter) powers the IDR.
The IDR is available in two models:
! IDR with an internal antenna
! IDR with a TNC connector for connecting to a third-party external antenna

Warning: To avoid electrical or fire hazard, ensure that all connections to the
IDR are performed prior to connecting the power supply.
Note: The digital portion of the transceiver has been tested and found to
comply with the limits for a Class B digital device, pursuant to part 15 of the
FCC rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment on and off, the user is encouraged to try correct the
interference by performing one or more of the following measures:
- Reorientate or relocate the receiving antenna
- Increase separation between the equipment and receiver
- Connect the equipment to an outlet on a circuit different from that to which
the receiver is connected
- Consult the dealer or an experienced radio/TV technician for help

10.3.2. Wall and Pole Mounting
The IDR may be mounted to a wall or to a 5-cm diameter pole. Wall and pole
mounting both use the same mounting brackets and wall hanger plate.
10.3.2.1. Assembling the Bracket and Hanger Plate
The wall hanger plate secures the IDR to a wall or pole. The wall bracket and hanger
plate allows positioning the IDR in the correct orientation. Holes are provided in the
wall hanger plate for both pole and wall mounting options
To assemble the bracket and hanger plate:
1. Insert a 4 mm hex nut into the slot on the tilt arm component
2. Holding the nut in place, attach the tilt arm to the mounting bracket using a 4
mm socket head bolt. Hand tighten the bolt only. See Figure 10-5.
3. Affix the complete mounting assembly to the rear of the IDR using the 4-off
self-tapping screws supplied with the kit.

10.3.2.3. Wall Mounting
Warning: Prior to drilling holes in a wall ensure that there are no hidden
services such as electricity cables or water pipes. A stop must be used on the
power drill to ensure that bored holes do not exceed 35 mm.
To mount the IDR on a wall:
1. Loosen the 2-off M4 socket head screws on the mounting bracket tilt-arm and
remove the wall hanger.
2. Offer up the wall hanger to the wall and scribe through the mounting hole
locations.
3. Drill holes to suit the type of wall fixing.
4. If required insert anchor plugs suited to the wall material.
5. Affix the wall hanger using 4-off screws suited to the anchor plugs and wall
material.
6. Re-attach the IDR mounting bracket to the wall hanger. Finger tighten the
screws.
7. Position the IDR at the desired inclination.
8. Re-tighten the screws to lock the IDR in position.

10.4. Connecting a Third-Party External
Antenna
The IDR provides a TNC-type connector for connecting a third-party antenna to the
IDR. This antenna can be placed on the subscriber’s windowsill to provide better RF
signal reception with the BSR.
Note: Airspan supplies unterminated cables for N-type connectors. Therefore,
refer to the cable crimping procedures for N-type connectors detailed in
Appendix B, “Cable Crimping".
! Connector: TNC-type male
Warning: Before connecting the external antenna, ensure that the IDR is NOT
connected to the power source.

Warnings:
1) It is the responsibility of the person installing the WipLL system to ensure
that when using the outdoor antenna kits in the United States (or where FCC
rules apply), that only those antennas certified with the product are used. The
use of any antenna other than those certified with the product is expressly
forbidden in accordance with FCC rules CFR47 part 15.204. The installer
should configure the output power level of antennas according to country
regulations and per antenna type.
2) Indoor units and antennas should be installed ONLY by experienced installation
professionals who are familiar with the local building and safety codes and are licensed
by the appropriate government authorities.

10.7. Connecting to PC for Serial Configuration
To perform IDR initial configuration, you need to connect the IDR’s RJ-11 port to
the serial port of a PC running the WipLL network management application (i.e.,
WipConfig).
The IDR’s RJ-11 port labeled Serial, located on the front panel, connects to the
serial port of a PC via a cable with an RJ-11 connector on the one end, and a 9-Pin
D-type connector on the other (i.e., a direct serial cable connection-DCC).
! Connectors:
! 6-Pin RJ-11 male to 9-pin D-type female adapter
! 9-Pin D-type male to 9-Pin D-type female adapter
! Cable:
! Straight-through cable with 6-Pin RJ-11 male on one end and 9-Pin D-type
female on the other (connects between IDR and crossover cable)
! Crossover cable with 9-Pin D-type male on one end and 9-Pin D-type
female on the other (connects straight-through cable to PC)

10.8. Connecting Power
The IDR is powered by an external power supply (Triple Output External Adapter).
The IDR connects to the power adapter via the IDR's power port located on the
IDR’s front panel.
The following table lists the external power supply specifications:
Table 10-4: IDR power supply requirements
Power parameter Units
Voltages 110-240 VAC
Frequency 50 to 60Hz
Maximum power
consumption
Less than 15W
Warning: If you are using an external antenna, ensure that you connect the
antenna before connecting the BSR to the power source.
Warning: Ensure that plugs fitted to mains power leads for subscriber
premises equipment are compatible with AC mains sockets. Do not replace
plugs on power leads to suit local requirements without first verifying earthing
practice for the country and equipment in question.
Careful consideration must be given to issues including local wiring
requirements, cable color-coding, and safety earthing and circuit protection
requirements.
Warning: To avoid electrical or fire hazard, ensure that the data connections
to the IDR are made prior to connecting the power supply.The AC mains must
be capable of supplying at least 230 VAC
Prior to connecting to the power outlet, the following pre-connection inspection
should be performed on power sockets:
! Power socket shall be visually inspected to ensure that no other equipment is
connected to the power outlet.
Installing the IDR Hardware Installation Guide
10-24 Airspan Networks Ltd. 02030311-06
! There is no physical sign of damage to the power outlet.
! There should not be any visible sign of water or dampness on or around the
power outlet.
! The plug and socket assemblies are to be firmly secured.
! The power outlet shall be checked using a proprietary plug tester such as a
‘Martindale Ze’ type. Checks are required to verify the earth loop impedance
value and the presence of phase, neutral and earth connections.

To connect the power:
1. Plug the AC power adapter’s 6-pin Molex connector into the IDR’s power port
labeled Power (see Figure 10-15).
2. Plug the AC power plug female, at the one end of the AC power cable, into the
AC power adapter’s socket (see Figure 10-15).
3. Plug the AC power plug male, at the other end of the AC power cable, into the
electrical outlet (see Figure 10-15).
