DAB1 DISTRIBUTED AUDIO SYSTEM
RS-232 Command (Outbound Serial Control)
The DAB1 can issue macros containing outbound serial control strings to a device in
the system via its RS-232 connector (see

Figure 14

, on page 17).
To create an RS-232 macro command set the following parameters and then drag the
icon into the MACRO Window (see

Figure 60

):
BBaauudd RRaattee Select the correct baud rate from the drop-down box for the device
being communicated with.
FFoorrmmaatt Select the appropriate format from the drop-down box for the serial line of
the device being communicated with:
88NN11= eight data bits, no parity, one stop bit
77EE11= seven data bits, even parity, one stop bit
77OO11= seven data bits, odd parity, one stop bit
77MM11= seven data bits, mark parity, one stop bit
77SS11= seven data bits, space parity, one stop bit
CCoommmmaanndd SSttrriinngg RS-232 commands can be in either ASCII text or Hex code.
• If you’re typing ASCII text make sure that the HEX MODE button is not selected, then type the command into the STRING window.
If you’re typing a Hex command or importing a Hex command from another device, press the HEX MODE button first and then
type or copy the command into the window.
Once the proper command is in the STRING window drag the icon into the MACRO Window.
TTeerrmmiinnaall PPuullll--DDoowwnn— Select the terminal
(ending character) for the RS-232 command
from the pull-down menu:
\r = Carriage return
\n = Line feed
\k = Hex byte
\e = Escape
\t = Tab
\\ = Backslash
