Windows 95/98/NT Users

If you find yourself squeezed for room at the bottom of

the screen, you can modify the Task Bar so it only appears
when you move the mouse pointer below the bottom of the
screen.

To do this,

1. Right-Click on a blank spot on the task bar.
2. Select

Properties

3. Enable

Auto Hide

4. Press

OK.

While operating the Site Control Panel in Windows 95 or

98, there is no button-box for the system menu on the title
bar. There is, however, a Close-Window button-box.

As expected, the Close-Window button-box does exit the

Site Control Panel, but unfortunately, it also quits
RW 232.

To get back to edit mode, Right-Click the mouse on the

Site Control Panel title bar. This will open the menu allowing
you to return to Device Edit mode or exit the program
altogether. As usual, a password is required for either option.

TROUBLESHOOTING

POWER LED is Off:

Check POWER connection on rear panel, and that the remote

supply is connected to a live AC source.

No communication between the unit and the com-
puter:

Set the DEVICE ADDRESS to a unique small number,

and try polling for units in RaneWare (under

Device >

Select, Poll

). The unit should be found quickly. If more than

16 units are daisy-chained from one serial port, communica-
tion to the furthest units may be unreliable.

Check that the COM port selected in RaneWare (under

Setup > System Setup

) is the one on your computer that is

connected to the unit.

Check that the cable is a standard RS-232 cable (not a null

modem type). If an adaptor is used,

it must not be null

modem

. The cable must be connected to the RW 232 INPUT

jack on the rear of the unit.

Bypass can't be turned off:

The unit is probably waiting for the computer to download

firmware. Removing and reapplying power to the unit will
prompt it to revert to the last firmware.

Audio hum or noise:

Try Muting the unit. If this helps significantly, the

problem may be with the Input connection, or the equipment
driving the Input. If Muting has little effect, the problem is
likely either the Output connection, or equipment driven by
the Output.

The RPE 228d is intended to connect with equipment with

balanced audio I/O and chassis-grounded shield/common.
This kind of audio interconnection should maximize audio
quality. Connecting equipment with signal grounded shields
or unbalanced connections may result in hum or noise due to
induced currents in the signal path. It may be possible to
reduce or eliminate these problems, although some experi-
mentation may be required:

Try disconnecting the audio cable shields at one end,

particularly between chassis grounded and signal grounded
equipment.

Try combinations of lifting grounds on units supplied with

ground lift switches (or links).

Verify that all chassis are tied to a good earth ground.
Units with outboard power supplies do

not

ground the

chassis through the line cord. Make sure these units are
grounded by tying the Chassis Ground Point to a known earth
ground. A star washer guarantees proper contact.

For more information on balanced interconnection and

grounding, please refer to RaneNote 110, “Sound System
Interconnection”(next section).
