Relay Stations - Worth Data 7100 RF Terminal Series Owner's Manual

If the Base Station is powered up, walk to the area where you want to perform your first test (start at 50 ft. or greater). When in
position, stop and look at the RF Terminal display. It should read:
Press Enter When Ready
or F1 to Exit
Press the ENTER key to start the test. During the test (about 10 seconds), hold still during the test – moving around can result in
inaccurate results. During the test the RF Terminal is transmitting many messages and waiting for acknowledgement from the
Base Station. During the test the following message displays on the RF Terminal screen:
Site Testing in Progress,
Please Wait..............
Please Wait... will display on your screen until the test is finished. If it takes more than a few seconds, there is something
wrong. When the test is finished, you will see the results displayed in the following format:
st
1
nd
2
Press Enter When Ready
or F1 to Exit
The first line shows the percent of successful transmissions. As long as you are getting at least 90%, you will have excellent results in the
location tested. You can still get decent performance with results around 50% but there will be some slight delays due to re-
transmissions.
If you don't get the minimum results shown above:
1. Try hanging the Base Station upside down or tilted toward the area of usage – this alone can double the effective
range.
2. Try locating the Base Station closer to the area of difficulty. Remember that moving the Base Station will require
you to recheck the other locations already tested.
3. If none of the above works, you will have to consider using a Relay.

Relay Stations

Since the range of the 7100 Terminal is quite large you probably won't need a relay unless you must have coverage in more than
one location that is difficult to cover with a single base. An example of this would be inside two or more metal buildings where a
base would be in one building and a relay in the other. Relays work like a remote antenna, passing data to the Base Station via ca-
ble instead of radio frequency. Base Stations are used as Relay Stations by changing the jumpers inside. See Appendix A for de-
tails.
Relay Stations are attached to the Base Station using a cable that connects from the Base's RELAY port to the Relays' RELAY
port. When you order a Relay Station, you receive a 3-foot test cable with it. Although Relay Stations will increase your range of
operation, they will also add about ½ second to the response time.
How Relay Stations work...
It helps to know how Relay Stations work before you add them to your system. Although Relays increase your operational
range, they also slow the response time of your system. In order to use Relays, the Terminal must be configured to
acknowledge that Relays are present. This is done using the Relay Existence setup parameter. By default, the RF Terminal is
not configured to look for Relays. See Chapter 2; RF Terminal Setup for details.
