Remote control interface operation
RS232 interface
This interface is fitted as standard to all units and is accessed via the 9-pin D-type connector on the rear
of the unit. Note that to connect to a computer's COM (serial) port correctly, a one-to-one cable must be
used, and NOT a 'null modem' cable. A 'null modem' cable has the 'transmit' and 'receive' wires swapped
over and will not work.
The RS232 connection is suitable for distances of about a maximum of 25 feet (7.62 m) between the PC
and the unit. If you experience problems with the connections, consider
?selecting a slower baud rate
?selecting the 'Use Acknowledge Cmd' option in AudioCore (see the Remote Menu > RS232
Configuration window)
?running the unit via the RS485 interface
Note than only one unit at a time may be connected to the computer via this interface. Additional units
may be 'daisy-chained' via the RS485 connections from the back of the first one (it acting as a converter for
them), but their RS232 ports are not used.
RS232 Connection (Single Unit)
A typical interface set-up might involve running an RS232 link from laptop or a desktop computer to a
DSP-2060A unit set up as a master unit. The diagram below shows this method of connection, the required
menu options are also given. Note that the RS232 cable must be a 1-1 connection type, NOT a null modem
cable (which has connections crossed internally).
