6Serial Communications

To interface the Vision 65/75 with a home theater automation/control system or a PC running terminal emulation software:

1.Connect it to your control system or PC as shown in Figure 3-14.

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

3.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.

4.Type a command from among those listed in Table 6-1.For example, to select the Component 1 input, type X133X. Do not send a carriage return after the command.

Serial commands to the Vision 65/75 take the following form:

•Commands are in ASCII format.

•Commands must be in UPPERCASE; for example, X001X, not x001x.

•When you send a valid command, the Vision 65/75 executes it and echoes the command back to the PC or control system. For example, when you send the command X001X, the Vision 65/75 responds with X0_001X<CR>.

•When you enter an invalid command, the Vision 65/75 simply ignores it.

The Vision 65/75 will not accept serial commands for 20 seconds after it is

Note turned on or off.
