Q-750d Ultra Series Installation/Operation Manual 87

In addition to using the DHD Controller front-panel keypad or remote control unit, there
are three methods of controlling the Q-750d Ultra and DHD Controller externally:
• Using a serial (RS-232) link to send ASCII commands and receive responses to those
commands.
• Using discrete infrared (IR) codes to program a third-party remote control unit.
• Using an HDMI connection to send Consumer Electronics Control (CEC) commands
from a BD player or other source component that supports CEC.
The following sections describe these methods.
6.1
Serial Communications
The DHD Controller uses a simple text-based control protocol to take requests from
control devices and to provide responses to such devices. This section describes how to
send control messages over a serial link between the DHD Controller and an
automation/control system or a PC running terminal emulation software.
RS-232 Connection and
Port Configuration
To interface the Q-750d Ultra with an automation/control system or a PC running terminal
emulation software, connect it to the Display Control output of the DHD Controller as
shown in Figure 3-10 and Figure 3-11. Connect your control system or PC to the RS-232
input of the DHD Controller as shown in Figure 3-18.
Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop
bit and no flow control. Set the baud rate to 19200, to match that of the DHD Controller
RS-232 port.
Command FormatCommands sent from an automation/control system or PC to the DHD Controller must
have the following format:
(www:xyz) [CR]
Where:
• ( and ) indicate the start and end of the command data. If these characters are
present, the DHD Controller assumes that valid command data is present in the
command string. Otherwise, the DHD Controller ignores the command.
• www indicates the command code. This field is case insensitive; for example, PWR, pwr
and PwR are all equivalent.
• :x is the destination parameter. This is an optional parameter that indicates which
memory the command is referencing. This parameter is reserved for future use.
6. External Control
The serial communication protocol described here replaces the
serial protocol used by legacy Runco products (manufactured prior
to September 2011) that include the DHD Controller.
Runco recommends using this new protocol, as it is more concise
and provides greater control than the old one. However, to maintain
backward compatibility with existing automation/control system
modules, the legacy Runco serial protocol is also supported.
