8 Dolby ® DP570 Multichannel Audio Tool User’s Manual
Getting Started
2.4.3 Hardware Connection
To connect the DP570 to its remote control device, use a serial cable from your computer to
either the front‐panel
Remote RS-232 port or the rear‐panel Remote RS-485 port. For
connector and pin descriptions, see the Section B.1 and the Section B.8 .
2.4.4 Configuring the Unit for Remote Operation
A DP570 arrives preconfigured to communicate with the remote application at 115,200
baud, using a unit address 8280.
The remote response from the unit is fastest at 115,200 baud, so we recommend using that
rate if possible. The unit does support slower communication rates. The unit address is
only important when more than one DP570 is attached to the same COM port. Contact
Technical Support if you need assistance with unit addressing in that situation.
You can change the default remote operation settings from the unit front panel on the
System Settings
portion of the Setup menu. Follow these steps.
1. At the main status screen, shown in the Figure 3‐3 , press the Setup button.
2. At the main Setup menu, press until the LCD second line reads System
Settings (seven times).
3. Press Enter .
4. Press . The second line reads Baud Rate. Press Enter if you need to change it.
Then press until the baud rate you wish to use appears in the display. Then press
Esc to return to the main system settings menu.
5. Press twice. The second line reads Unit Address. Press Enter if you need to
change it.
6. Enter a new unit address using the procedures for text entry explained in detail in
Section 3.5.2 .
2.4.5 Beginning and Ending Remote Operation
To begin remote operation, on the front panel press and release Shift once so that the button
lights up, then press . While in Remote mode, the front‐panel LED labeled Remote
glows green, and setup commands cannot be made from the unit front panel. The status
menus, discussed in
Section 3.4 , continue to display accurate unit status in Remote mode.
To end remote operation and resume using the front‐panel interface, press Shift then
again.
Note: You can use a USB‐to‐serial adapter to connect the serial cable to a laptop. However,
these adapters occasionally cause enough delay to interfere with data
communications. This problem is mostly likely to occur during firmware upgrades.
Take care to establish the best possible connection before beginning an upgrade.
