RS-232 Connection and
Port Configuration

To interface the Vision 110 with a home theater automation/control system or a PC running
terminal emulation software, connect it to your control system or PC as shown in Figure 3-15.
Use a null-modem cable.

If you are using a PC to communicate with the Vision 110:

1.

Start a terminal session on your PC using a terminal-emulation program, such as
HyperTerminal.

2.

Configure the 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 Vision 110 RS-232 port.

3.

Press . You should see a command prompt (>) in the terminal window.

4.

Type a command from among those listed in Table 6-1 and press .

6.2
Serial Command Syntax

Commands are in ASCII format and are not case-sensitive; on and ON are equivalent.

For a command that takes no parameters, type the command followed by a carriage
return; for example, to turn on the system, type ON.

For a command that takes a parameter, type the command, one or more spaces and the
desired value followed by a carriage return; for example, to switch to the S-Video input,
type SSRC 1.

When you enter a valid command, the Vision 110 executes it. When you send an on/off,
input selection, aspect ratio or image preset command, the Vision 110 also responds with
an acknowledgment on the command line. For example, when you issue the command
SAR 2,

the Vision 110 responds with Letterbox on the command line.

When you enter a misspelled or otherwise invalid command, the Vision 110 ignores it and
responds with Invalid Command on the command line.

When you send a command followed by values outside the valid range for that command,
the Vision 110 ignores it and responds with Invalid Parameter on the command
line.

When the Vision 110 receives an OFF command, it will not acknowledge or execute any
commands for approximately 90 seconds afterwards. This is to prevent hot re-strikes of
the lamp, which can damage it.
