As the
DP6i
has been designed primarily for installation purposes, the choice of
which remote interface to use is very important. This section explains the different
interface options and how to choose the best one for your application.
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 25feet
between the PC and the unit. If you experience problems with the connections,
consider
-
selecting a slower baud rate (interface
02
or
04
)
-
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.
The RS232 interface may be used for full remote control and metering/monitoring of
the unit.
