In addition to using the Dimension Digital Controller front-panel keypad or remote control
unit, there are three methods of controlling the SC-30d/SC-35d and Dimension Digital
Controller externally:
• Using a serial (RS-232) or TCP/IP (Ethernet) 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 or TCP/IP
Communications
The Dimension Digital 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 or TCP/IP link between the
Dimension Digital Controller and an automation/control system or a PC running a terminal
emulation or Telnet client program.
RS-232 Connection and
Port Configuration
To interface the SC-30d/SC-35d with an automation/control system or a PC running
terminal emulation software:
1. Connect the projector to the DHD Controller as shown in Figure 3-13.
2. Connect your control system or PC to the RS-232 input of the DHD Controller as
shown in Figure 3-15.
3. If you are using a PC, start a terminal session using a terminal-emulation program, such
as HyperTerminal.
4. Configure the RS-232 controller or PC serial port as follows: 19200 bps, no parity, 8
data bits, 1 stop bit and no flow control.
Using TelnetTo interface the SC-30d/SC-35d with a personal computer running a Telnet client:
1. Connect the projector to the DHD Controller as shown in Figure 3-13.
2. Connect the Ethernet port of the DHD Controller to your network router, hub or
gateway as shown in Figure 3-18.
3. Set the DHD Controller IP Address, Subnet Mask and Default Gateway so that the DHD
Controller and PC are on the same subnet (refer to IP Configuration on page 90).
4. From the PC, start a Telnet session using the IP address you configured in Step 3.
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.
