Serial controlSerial control
The HDMA-4000 can be controlled from a device connected to the serial port.
The HDMA-4000 has two serial command modes: Pioneer LD/DVD mode, which is
more compatible with a Pioneer CD/DVD, and HDMA-4000(Ver.1.1x) mode, which
is a traditional serial control command mode.
These modes can be changed via a Web browser’s settings page. (See Reference 4).
Note
Synchronized playback of the HDMA-4000 is only available in the Pioneer
LD/DVD mode.
- Connection
Connect a device which has a RS-232C port to the HDMA-4000 with a serial
cable (to connect to a PC, use a cross-over cable).
- Network transmission setting
The default settings are: 9600bps, 8bits, no parity, stop bits 1. The settings can
be modified with a WEB browser (See Reference 4).
- Command
The two characters, <CR>(0x0d) are required at the end of the command line.
When the connection and the settings are done properly, R<CR> is returned. If
an error occurs, xx<CR>* is returned.
* xx Substitutes for the error number.
Multiple commands can occur on a line (Up to 25 characters).
In command controls, do not issue further commands until a response has been
received to the previous one.
When network serial control is enabled on the Web console, the HDMA-4000
can be controlled with the same commands via the network. (Connect a device
to a specified port, 12000 is the default setting, with terminal communication
software such as Telnet.)
Note
In serial control mode, files with the extension m2p, m2t or mpg are
recognized as content files.
