RS-232 Connection
and Port Configuration
To interface the RS-900/RS1100 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 3-17.
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.
6.2
Serial Command
Syntax
Serial commands to the RS-900/RS1100 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 RS-900/RS1100 performs the following actions:
1. Echoes the command back to the PC or control system, unless the command is
X001X (Power On).
2. Executes the command.
3. Sends a confirmation message in the form X0_[command number]X<CR>. The
confirmation message does not include the leading zeros in the command.
For example, when you send the command X003X, the RS-900/RS1100 responds
with X003XX0_3X<CR>. When you send the command X061X, the RS-900/RS1100
responds with X061XX0_61X<CR>. When you send the command X133X, the
RS-900/RS1100 responds with X133XX0_133X<CR>.
• When you enter an invalid command, the RS-900/RS1100 echoes the command and
does nothing else.
6. Serial Communications
The RS-900/RS1100 will not accept serial commands for 20
