INSTALLATION
U4 Receiver Connection
NOTE: At least one Shure U4S or U4D UHF receiver is required to install the UA888 system.
1. Install the UA888 in a 19-inch audio equipment rack. Refer to Appendix A.
2. Using the supplied 1 meter (3 ft.) cable, connect the 25-pin D connector labeled “Receiver A” on the rear
panel of the UA888 to the 25-pin D connector on the rear panel of a U4 receiver. See Figure 3.

Installing UA888 Software
To install the UA888 software on your computer, proceed as follows:
1. Turn the computer and the UA888 Interface Module on.
CAUTION:LeavetheUA888InterfaceModuleturnedonwhileitisphysicallyconnected tothereceivers.
Turning it off while the receivers are connected can affect receiver metering. However, it will not affect
receiver performance.
2. Insert the supplied 3.5 inch diskette into the floppy drive on the computer.
3. If you are using Windows 3.11, click on the “File” heading on the main menu, then click on “Run.”
If you are using Windows 95 or Windows NT, click on the “Start” button at the bottom of the window and
select “Run.”
4. In the “Run” window, type “a:\setup” where “a” is the drive containing the UA888 diskette. The software will
check the computer hardware to ensure that a coprocessor is present and suggest a destination for the
UA888 files on the hard disk. It will also prompt you to type in your name and organizational information.
NOTE: Pleaseregister your software by completingand mailing the enclosed registrationcard. Youmay
also register on line via the Shure web site at http://www.shure.com.
Linking Multiple UA888 Interface Modules
A maximum of 32 Shure UHF receivers (up to 64 channels) can be monitored and controlled from a single
computer by linking multiple UA888 Interface Modules and their associated receivers as follows:
NOTE: Legal and practical rf considerations may limit the actual number of channels used to less than 64.
1. Assign each Interface Module a Device Identification Number (0–3) by sliding the DIP switches on the
rear panel up or down, as shown in Figure 5.

NOTE: The UA888 must be turned off, then turned back on, for the DIP switch settings to take effect.
2. Using the supplied 5-pin DIN cable, connect the Shure Link OUT port of the first UA888 (the one con-
nected directly to the computer) to the Shure Link IN port of the second UA888. See Figure 6.
3. Connect the Shure Link OUT port of the second UA888 to the Shure Link IN port of the third UA888.
4. Connect the Shure Link OUT on the last UA888 to the Shure Link IN on the first UA888. This creates a
communication loop between all networked UA888 Interface Modules and the computer.
NOTE: Although standard MIDI cable can be used, Shure Link is not MIDI compatible.

Answers to Commonly Asked Questions
“I can’t change receiver settings, or even monitor all of them, with the UA888. Is
there something wrong with my system?”
No,there is nothing wrong with your system. Youjusthavesome older U4 receivers. Version1.5xandearlier
require an upgrade before they can support all UA888 monitoring features, or any of the remote control fea-
tures. An Upgrade Kit is available. There are two ways to determine which version of the Shure U4 receiver
you have:
1. Turn the receiver on and hold down the “+” and “–” buttons on the receiver front panel. After a few sec-
onds, the version number will appear on the display.
2. Look for a label on the rear of the receiver that identifies it as “Version 2” or later.
“The rf and audio meters on my U4 receiver are not working properly. Is it pos-
sible for both meters on each receiver to go bad at the same time?”
Itisextremelyunlikelythatbothmeterswouldfailsimultaneouslyonmultliplereceivers.However,theaccura-
cy of the U4 meters can be temporarily affected if the UA888 is turned off while the receivers are still on. Turn
the UA888 Interface Module back on and leave it on.
“Nothing happens when I try to select Open Scene. What should I do?”
You need to connect the UA888 to the U4 receiver(s). Both a hardware and a software connection are re-
quired. You can make these connections as follows:
1. Make sure the U4 receivers are properly connected to the the UA888. An RS-232 cable should run from
the25-pinNetworkInterfaceconnectorontherearpanelofeachU4receivertooneofthe25-pinconnec-
tors on the rear panel of the UA888.
2. Go the the main menu bar on the computer display and click on the ”Set Up” heading. Select “Connect”
from the pull down menu.
“Is there a way to turn off the password protection?”
Yes. Here it is:
1. Cllck and hold on the Security heading in the main menu bar and highlight “Password” and “Deactivate
Password Protection.” Then release the mouse button.
