Ecler CA200z - Manual (Page 9)

The total volume of each output is a result of the concatenation of the
MASTER volume, adjusted with the rotary encoder knob on the CA200z's front
panel or with the infrared remote control, and the REMOTE volume, adjusted with
each associated panel, if any.
When actuated, the remote panel volume is displayed for a few moments on
the front panel's LCD screen with the text REMOTE VOL 1 or 2 and a volume bar.
In ZONES mode, this volume is only displayed if the zone associated with the
panel in question has been selected on the screen.
Note: See section 4.2 Special setup mode for instructions on how the operating modes of the
ports REMOTE1 and REMOTE2 are programmed.
Note: Configure the internal jumpers on the WPmVOL or WPmVOL-SR panels in 10V/Alog mode
for the CA200z to operate correctly
 MUTE port: the MUTE connector on the rear panel makes it possible to connect
an potential-free external contact closure to totally silence the CA200z if an
external device actuates on it (example: a centralised emergency and evacuation
warning system). For the MUTE port to be active, ports REMOTE1 or REMOTE2
can not be deactivated (OFF position)
o The REMOTE1 port must be active (other than OFF) for the MUTE port
to be able to silence both of the unit's outputs when it receives an
external contact closure in STEREO, MONO or BRIDGE modes
o When the port receives a single external contact closure in ZONES
mode, the REMOTE1 port must be active (other than OFF) for the
MUTE port to be able to silence output A, whereas the REMOTE2 port
must be active (other than OFF) for the MUTE port to be able to silence
output B
Note: See section 4.2 Special setup mode for instructions on programming the operating modes
of ports REMOTE1 and REMOTE2 to enable the silence function associated with the MUTE port
 RS-232 port: the serial communication port RS-232 allows remote management of
the CA200z from a computer or external control system supporting the CA-NET
protocol. See the CA-NET protocol manual for detailed information on connection
and the syntaxes of the supported commands. The serial connection specifications
are as follows:
o Baud rate: 9600 (fixed, without auto-negotiation)
o Data bits: 8
o Parity: None
o Stop bits: 1
o Flow control: None
o Cable: standard RS-232 DB9-DB9 (pin to pin)
 IR receiver: the integrated IR receptor enables controlling the CA200z with the
remote control that comes with the unit:
o Zone selection keys (ZONE A / B). Enables selecting the output zone
that will be adjusted afterwards. After pressing the A or B key it will be
possible to adjust the MASTER volume, use the MUTE control, select
audio sources, etc. It is possible to change the selected zone on the
unit's front panel by briefly pressing the front rotary encoder knob (only
in ZONES mode).
