Section 1. Using This Guide
This guide describes how to install and use a WavePhore Intelligent Data Receiver™
V1000 (IDR V1000). The IDR V1000s comprise a family of satellite receivers that
receive, demodulate, and process data streams over high-speed carriers. These data
streams supply real-time news, market information, and other subscription services to
businesses.
The IDR V1000 family includes four models. The models are virtually identical in
appearance and basic operation, but they each provide a unique set of data handling or
connectivity options:
•The basic model (1235) provides the basic receiver capabilities with one
asynchronous, serial output port.
•The 4-port model (1236) includes the optional 4-port serial daughtercard for
multiple serial output connections.
•The Reed-Solomon model (1216) includes the integrated Reed-Solomon Forward
Error Correction capability along with the additional 4-port serial output ports.
•The Ethernet model (1233) includes the optional Ethernet daughtercard for
connection to Local Area Network (LAN) devices.

Safety
Issues
Following some basic, common-sense procedures will protect you and will help keep
the IDR V1000 operating without disruption.
Do:
•Unplug power before changing external cables.
This reduces the chance of electrical shorts that could damage the receiver.
•Protect the IDR V1000 from liquids and excessive heat, humidity, or dust.
These elements can damage or wear electrical components.
•Connect the IDR V1000 to grounded power outlets.
Do Not:
•Open the casework.
Nothing inside the IDR V1000 is field-repairable.
NOTE: Opening the casework for any reason is prohibited and will void the
warranty.
•Stack the receivers.
Vents in the receiver’s casework are designed to provide the necessary ventilation
to the components. While the foot pads on the receiver may help provide
sufficient space for ventilation, stacking is not recommended.

MS-4900, Rev. A 2–1
Section 2. Installing the IDR V1000
The installation process covers the following steps:
1. Ensuring all cables are properly connected.
2. Tuning the IDR V1000 to its maximum achievable levels for that site
3. Notifying the network operator that installation is complete and to download the
appropriate services as necessary.
For more descriptive detail on the screen displays, refer to Sections 3 and 4.
Before You
Begin:
First, verify the current conditions:
1. A suitable satellite dish (with lightning protection) is already installed
2. Coaxial cable is already run from the dish to the receiver location. (RG-6 cable
is recommended, length not to exceed 500 feet.)
3. RF coaxial cable shield is connected to earth ground with a #10 gauge (or
heavier) solid copper wire at the point of entry to the building.
4. Output data cables are shielded, with shield wire attached to connector shell at
both ends of the cable.
5. Power module is not yet connected to the IDR V1000.
CAUTION: To prevent accidental shorts from causing circuit damage, the power
module should always be disconnected during installation or
whenever cables are being changed.
In addition:
•You should know the expected Eb/N0reading and AGC levels for the site.
Contact the network operator now if you do not have this information.
•Read through the safety issues in Section 1.
CAUTION: Rain, snow, high winds, or extreme cloudiness can attenuate the
signal. Do not attempt to install the receiver during inclement
weather.

Installing the IDR V1000
2–2 MS-4900, Rev. A
Step 1:
Connect
The Cables
1. Connect the coaxial cable to the RF Input connector
2. Connect data cables between the serial or Ethernet outputs on the IDR V1000
and the external devices. See Figures 2-1 and 2-2.
3. Connect the power module to the IDR V1000 power input and to the power
source.

Installing the IDR V1000
MS-4900, Rev. A 2-3
Step 2:
Verify
Initial Lock
On Carrier
As soon as power is supplied to the IDR V1000, an automatic self-test runs. The IDR
V1000 then locates and “locks” onto the preset frequency. When this completes
successfully, the following identification screen appears (Figure 2-3).
Figure 2-3. WavePhore Identification Screen
If you do not see the identification screen within two minutes of powering on, or if you
see a character other than the “L”after a minute or two of the screen being displayed,
refer to Section 4 to troubleshoot the cause.
Step 3:
Check
Eb/N0and
AGC
Readings
After the receiver has achieved initial lock on the carrier, you should try to “peak,”
or maximize both the Eb/N0 and AGC numbers. You can see both readings in the
Show Status screen (Figure 2-4).
NOTE: Refer to Section 3 for instructions on using the front panel buttons to
display screens.
Figure 2-4. Show Status Screen: AGC and Eb/N0 Readings
1. The AGC level indicates that cabling is complete and the LNB is powered.
Ideally, the reading should be near 200. If the number is under 100, check the
coaxial cable connections and the LNB on the satellite dish.
2. The Eb/N0reading indicates signal quality; it is possible to fine tune that
reading by slightly adjusting the positioning of the satellite dish. The Eb/N0
should be at least 5.0, usually higher. (The site will have specific
requirements.)

Step 4:
Call the
Network
Operator
Once the Eb/N0 and AGC readings are at the expected levels and the Eb/N0 has been
maximized by adjusting the dish alignment, notify the network operator that the
receiver has been installed and is ready to be downloaded.
The operator may provide you additional instructions following the download.
NOTE: If the IDR V1000 was pre-configured at the factory, the necessary
settings may already be established and do not need to be downloaded.
Verify this with your site coordinator.
Step 5:
Maintain
the
Equipment
Satellite transmission can be adversely affected by bad weather. High winds can
knock a satellite dish out of alignment, and heavy snows, rain, or cloud cover can
severely diminish signal quality. You, or another designated individual at the site,
should attend to the following:
•Check satellite dish alignment (by monitoring the Eb/N0 reading) following
heavy or gusty winds.
•Remove snow from satellite dish using a stiff whisk broom.
•Make sure snow doesn’t accumulate on the dish and that the LNB window is
clear.

Section 3. Using the Front Panel
This section describes how to use the front panel of the IDR V1000 to view or modify
receiver settings. This information includes the following:
•Displaying and deleting messages
•Viewing and modifying configuration parameters
•Changing screen locks, password access, and local time
Configuration parameters typically are preset at the factory or are downloaded by the
network operator. The 2-line, 24-character LCD display on the front panel of the IDR
V1000 provides useful access to view these parameters, along with current activity
and status messages. You may be asked to monitor some of these displays routinely,
or you may be asked by telephone support personnel to describe the current settings.
Appendix C is an illustration of the entire screen display structure. Refer to Section 4
to interpret the displays.
Viewing
the Main
Topics
The eight screens shown in Figure 3-1 are the main topics of the screen display
hierarchy. (The identification screen is not one of the main topic screens, but it is the
