Troubleshooting

5.1Opening a Device

If the DolbyRemote application is unable to communicate with the unit, check the following:

DP569/DP567

Make sure the unit is in remote mode (press shift-left arrow). The remote LED should be lit.

Make sure that you are either using a RS-232 connection through the front panel or a RS-485 (RS422 for DP567) connection through the rear panel.

Verify that the baud rate and device address of the unit to be controlled match the parameters given to the DolbyRemote application in the Open Device window. On the unit, these parameters are found in the Operating Mode section of the encoder setup menu.

DP561

Make sure the unit is in remote mode; press shift-C on the keyboard. The VGA screen should show that the unit is in remote mode. It is possible to program the DP561 to always boot up into remote mode. Consult the product manual for details.

Make sure you are using a RS-232 connection into COM 1 of the DP561. This must be made using a null modem cable.

General

It is possible that hardware constraints on the controlling PC can cause problems with the remote connection. Both devices transfer data continuously to update dynamic information such as meter values. If the port is using a shared IRQ with another device then it is possible that the connection may be lost. In this case using another COM port can solve the problem.

If the connection is lost the unit will continue to operate with the current set of parameters contained immediately before the connection was broken, however it is not advisable to use the unit in this way if this problem persists.
