Microsoft DLL Files
If you have an older version of Windows® 95, you may see an error message about
Oleaut32.dll when you launch DolbyRemote. If this occurs, download and install the
Windows Library Update from Microsoft (
www.microsoft.com/windows95/downloads ).
1.5 Cable Installation
There are two types of serial interface used on Dolby products, RS-232 and RS- 485.
It is important to use the correct type of interface and the correct cable to ensure a
reliable connection.
Each RS-232 port on a PC must be connected to a single device, however, the
application can control many RS-232 ports. For example, with five free RS-232 ports
on a computer, five devices may be controlled with a single instance of the
DolbyRemote application.
A single RS-485 computer port may connect to several devices, provided the devices
all have an RS-485 connection.
DolbyRemote is shipped with a cable for RS-232 connection between a PC and the
front panel of a DP567/DP569 encoder. Connection to a PC RS-232 communications
port is made with the D-9 end of the cable. The other end of the cable connects to the
Remote port on the front panel of the encoder. Additional cables may be purchased
from Dolby Laboratories.
RS-485 connection for the DP567/DP569 requires a separate cable, not provided.
This connects to the rear panel serial port of the unit. Consult the product's users
manual for RS-485 support information.
Connection between a PC and a DP561 encoder requires a standard null modem
cable. The DP561 has only an RS-232 connection.
