Rename Zones
Rotary:
Press:
Buttons:
selects character
moves to next character
select Zone
By default, the eight output Zones appear in the display as
Zone 1 to Zone 8. This menu function allows the operator
to rename them (i.e. to allow rapid identication of the
building area).
The eight numeric buttons correspond to the eight Zones;
select that to be renamed.
The procedure used to rename the Zones is otherwise
identical to that described above for Music Inputs.
Rename Groups
Rotary:
Press:
Buttons:
selects character
moves to next character
select Group
By default, the four Zone Groups appear in the display as
Group 1 to Group 4. This menu function allows the
operator to rename them (i.e. to distinguish them more
readily from their component Zones).
The rst four numeric buttons correspond to the four
Groups; select that to be renamed.
The procedure used to rename the Groups is otherwise
identical to that described above for Music Inputs.
Set Key
enter keyButtons:
This menu function enables the DCM-1 Installer Mode key
to be changed from the factory default setting of 1234.
Changing the key from the default to one “less obvious” is
strongly recommended.
The key may be any 4-digit number, but comprised of digits 1
to 8 only.
Enter the new 4-digit key using the eight numeric buttons.
No additional actions are required for the new key to
become active.
RS232 Baud Rate
sets Baud RateRotary:
This menu function sets the data rate (baud rate) of the
DCM-1’s RS232 Control Port. If external control via RS232
does not form part of the system, the setting can be ignored.
Most external control systems are able to operate with a
wide range of baud rates. It may be simpler to set the baud
rate at the controller and leave the DCM-1’s setting at the
default.
The default setting is 9600 baud (displayed as 9600). Use the
rotary control to change the setting. Alternative baud rates
are 300, 1,200, 2,400, 4,800 and 19,200. The baud rate applies
to both data transmit and receive.
The numeric buttons are not used in this function.
RS232 Flow
sets RS232 Flow optionRotary:
Some external control systems require the RS232 ports of
devices under their control to be congured in a certain way,
particularly in regard to the way data ow between the
controller and the device is managed. The two most
common methods of data ow control are Xon/Xoff and
RTS/CTS, alternatively referred to as software control and
hardware control respectively.
The rotary control selects which of these control methods
is applied to the port. A third option, the default, is for no
ow control to be applied.
The numeric buttons are not used in this function.
Note that hardware ow control requires additional pins
on the RS232 port to be connected. See page 52 for more
details.
